Why don't running programs show in my taskbar

Once upon a time there was a task bar. (You know-that bar at the bottom of your screen that has the "start" button at one end and the time at the other end). You used to be able to see your task bar. You used to be able to see running programs in your taskbar. You could even click on those items and switch between programs. And then a dreadful thing happened.

They disappeared!

Quad core processors - the future is here!

You've always been fairly on top of things in the way of technology. You were one of the first people to buy and use a cell phone on a consistent basis. You've always been eager to experiment with new technology as soon as it arrives. Everything from digital cameras to black berries, to laptop computers and plasma screen TVs-you've tried it all!

And when you heard about dual core processors, you were one of the first to jump on it. As a serious gamer, it seemed like the natural thing to do, and all your friends and co-workers were in awe of your super fast and efficient computer. After all, a dual core processor is pretty sweet. Who wouldn't want the benefits it offers?

How do I move my old computer's hard drive to a new computer?

Adding a new hard drive device to your PC is a quick and simple process. However, there is not just one way to do it, no one size fits all. It can vary based on the type of computer you have and the type of hard disk. Adding a hard drive will mean opening up your PC and connecting the old drive in the right way to the right place. If you've never opened your computer before, fear not! Computer hardware may look intimidating, but the reality of it is that it is fairly user-friendly even for the most inexperienced techies. We will go through the basic steps involved with adding your hard drive

How important are computer clock speeds?

The importance of computer clock speeds depends on the applications the computer will be designated to run. General office work makes little difference about clock speeds. If you are trying to do high-end graphics or gaming, then it could be considered more beneficial.

Clock speed is a measure of how quickly a computer completes basic computations and operations. Therefore, the importance of the computer clock speeds relies on several factors.

How do I disconnect the touchpad on my laptop?

Most laptops with a touchpad have the ability to turn them off. However, each may have a slightly different method to turn them off. This article will cover a few of these methods and where to look for your specific computer.

You may find that using the touchpad when you are on the go can be very useful. However, when you are in a more permanent place, it may be easier to connect a `normal' mouse and use that instead of the touch pad. Touch pad technology has improved greatly from the first laptops, but they still take a little practice to get used to them.

Dual core processors - are they worth it?

Are dual core processors worth getting? Do you want to spend the time and money finding the right processor for your computer? Are dual core processors worth buying at this point in technology? Will they be compatible with my computer?

For you, the answer may be yes, it's definitely worth your time and money to get dual core processors. For others, the answer is no. It may not be worth it to get a dual core processor at this point. Whether or not it is worth getting depends on your purpose and computer use. A person who only uses their computer for word processing may find it is not worth it, while the person whose whole life is on the computer will find it more worthwhile.

AMD versus Pentium

So you've decided that you want a dual core processor. You've already asked yourself all the necessary questions to consider before getting one. Questions like "are dual core processors worth getting? Are dual core processors worth buying at this point in technology? Will they be compatible with my computer?" But you've decided that, yes, you do indeed want a dual core processor. Maybe you're a serious gamer and want to improve your game speed. Maybe you always have one thousand and one programs running on your computer and it can't handle it anymore and so you decide to get a dual core processor.

Whatever your reason is, you've made a good decision. Dual core processors offer great advantages over a single core processor. They can increase the speed of your computer, increase the efficiency of your computer (including making it more energy efficient!) and don't even use more power to run.

I have no C drive but some programs insist on it. What can I do?

You may or may not have a C: drive on your computer. You don't have to have one. However, some programs want to be installed on the C: drive only. In these cases we can create a virtual C: drive on the hard drive that you do have.

The C: hard drive is assumed to be the boot drive. However, any drive could be assigned to be the boot drive. The boot drive is where all of the start up programs are held. Most computers have the C: drive as the boot drive so some programs insist on being loaded in that directory. If this is the case, you can make a virtual drive to act as the C: drive.

You do not want to reassign the drive of your existing boot drive to C: if it is currently F: or G: or any other letter. This would create more problems than you already have. You may not even be able to get your machine to boot. If you reassign letters, the software settings will still be pointing to the original drive and will not look for the newly assigned C: drive.

How can I connect to my home computer from work?

You may have a need or desire to connect to your home computer from work. There are several factors that you must consider before trying to connect. Most importantly, will your work allow it and if it does will they help support it.

Your best method to find access to home would be to approach your IT department and see if they have software that supports access. Many companies realize that employees work at home and offer support to access files at home. Other companies feel that accessing home computers put their networks at risk because they can't control the security of home computers. If home computers are hacked by thieves then they could potentially gain access to the company through the home computer.

Tips for buying refurbished computers

Buying anything big is always a huge task. You want to make sure you buy the best product out there. You want to make sure that you aren't spending tons of money too. You want to make sure it's going to last and not break the first time you drop it. When you buy a computer, you have to think about all these things too. But if you are buying a refurbished computer, there are a few more things you have to look for and be warned about.

New computer technology

Ever since the computer was invented, our world has been changing. We have gone from doing simple things with a computer, like creating a program to write what we are saying, to things so complex you wouldn't even believe it was possible. Let's look at some of those things that seemed so impossible even five years ago, that we are doing today.

Turning on and off pop up blockers

If you spend much time on the internet, chances are you've come across some pop-up ads. These are most often advertisements for other websites or for various places. In some cases, they are ever inappropriate in nature and can display photos and ads for websites you don't want to visit. Other times, clicking on the ads can in turn put spyware and other malware on your computer.

However, there are a number of ways you can turn off these pop-up ads. You can download or buy software that will block pop-ups for you, or you can simply use the settings on your internet browser.

My computer tells me that a file does not have a program associated with it, what do I do?

Most of us love our computers. We need them for so many things. Emailing, blogging, looking up all that helpful information on the internet, and writing. These are just a few things that you can do with your machine. Most business these days requires that you use a computer. How would you function without a computer? Although we love these machines we know that they are extremely complicated. When they break most of us have no idea as to what to do. We spend lots of money to have a professional come and take a look at our machines even though we know that we could probably find out what is wrong fairly quickly. Without the training and without the time we need others to fix these sorts of problems. Technology is truly a mixed blessing. Perhaps you have found yourself standing and staring blankly at a computer screen, not sure what to do with a particular problem.

My computer is slowing down - what should I do?

Most of us rely on a computer for almost everything. We need a computer that will work quickly and efficiently to provide us with the information we need. Most business today has something to do with computers, and most of our personal lives rely on communications run through computers. Not having a computer can seriously handicapp you and keep you from important opportunities. If you don't have one you probably know what this means. Computers are great tools, but they are also extremely complicated and require a fair amount of knowledge to maintain and use. When something goes wrong with your computer you are probably in a panic.

You think you will not be able to fix the machine because it is so complicated, or because it will cost so much to do so. In many cases this might be the case, but many problems are the result of software malfunctions or settings and not some sort of harware issue. Of course, if you drop your computer out a third story window you might be in trouble. However, many routine issues can be taken care of by yourself, or perhaps quickly by a professional. Before you spend hundreds or thousands of dollars at a computer store, see if there is an easy way to fix your machine yourself. One common problem that many computer users complain of is that there computer is slowing down. This might occur after several years, or even just months of use. How will you possibly fix this problem, and what causes it?

How does the recycle bin work and how should I use it

There's a recycle bin with every computer. The recycle bin can also be called trash, garbage, or refuse. How does the recycle bin and work and how should you use it then? Let's talk.

The recycle bin is where all your deleted files go in order to make room on your hard drive for other files. Anytime you delete something from your computer be it a favorite website, any word documents or pictures that you have deleted. The recycle bin is easily found by the tiny little trash icon that represents it. Macintosh has had the trash can as part of the Mac operating system since the beginning and Microsoft introduced the recycle bin with Windows 95.

how do I make my computer run faster

Most people today have to work with computers in some way or another. Wether you are trying to send emails, do complicated mathematical formulas or any number of other functions, a computer is absolutely essential these days. This is especially true with our reliance on the internet. We buy and sell online, design businesses, and enact serious transactions. All of this is done with the simple click of a mouse on a computer. Given that these machines are so serious for our well being and our futures, it is obviously important that all of us have decent computers.

A bad machine or a cheep one can suddenly break down or loose precious files. A lost file could mean the end of business, or at least a very serious and embarasing mistake. The problems that can come from a bad computer are endless and very grave. However, another problem we have probably all had to put up with is that our computers can be very slow. With all of the different types of programs available, and with their wide spread availability, many computers have so much going on that they cannot handle it all. With several processes going at once they can only move slowly. When you watch a movie, read email, write a paper, and compose an Excell file you might run into a slow down. This might only seem like an annoyance, but a major slow down could mean that your machine will not be able to fulfill its basic functions and purposes. So how can you make your computer run faster? This can be a difficult question to answer, but there are a few basic steps you can take that should help.

How do I generate a SSH public key

If you are looking at accessing a computer over a secure channel you may need to generate a SSH public key. SSH uses a private/public key pair for identification purposes. The key pair is generated on your local machine or the client while the public key is then copied to the remote server or the host. The use of a SSH public key is a very secure way of administering a server.

Since SSH public keys are a good idea for security how then do you generate a SSH public key?
Here are some basic direction on how to generate a SSH public key.

how do I delete my google search history

The internet is one of the best things to come along in quite some time. If you are like most of us you know how useful this thing is, how absolutely important it is to business and to many people's personal lives. We shop online, send emails, and write blogs. Many of us like to spend our free time just surfing around the web in order to find some sort of ammusing video or piece of interesting information. Many of us like to get rid of extra time at work while surfing the web. We spend hours a day looking at web pages. There is nothing wrong with this as long as it doesn't affect our lives in a negative way.

So while it can be interesting and fun to find lots of interesting websites, many of us would not like other people to know which sites we look at. Just as you might not want others to know what TV shows you watch, what food you eat, what radio stations you listen to, and who you call on the phone, you might also not want them know which email sites you look at. Naturally you can only figure out which sites people look at by going to their computer and looking at something called a browser history. A browser history keeps track of all the different sites you have visited while surfing the net. It keeps track of the actual site address for each one. So how will you get rid of this trail of information left everytime you look at a website on the internet? And how will you do so if you use google, one of the most popular internet search engines?

how do I delete my browsing history

We all love the internet. It is such a cool toy for surfing and getting information. Conversely, it is also a remarkable business machine that can allow us to make millions of dollars. The internet is here to stay and there is nothing that we can do about it. With so much information coming over the net, how do you keep yourself safe? You share very personal information when you send emails or go to certain websites. You would not want someone knowing what books you read or who you call on the phone. You would not want anyone to know what television shows you watch or what radio stations you listen to. The world wide web creates similar dangers.

There is a record on your internet server that keeps track of all the websites you visit. This can be a great tool because it allows you to go back and find the sites you have recently visited. If you want to find the cool antique car site you looked at three hourse ago you can do so easily. The only problem is that anyone else with accsess to your computer can see the same thing. They can also go back and find all the sites you visited and look at what you have been looking at. How does that make you feel? For some of us this does not matter, but there might be something private you do not want other people to know about. Because this is only your business, and if you do not want anyone else knowing about what sites you visit, you need to learn how to eliminate your browsing history.

What to do when your computer video won't power up

Perhaps you have a big computer project due or simply need to sit down and get caught up on paying bills. You turn on your computer and the worse happens your computer video won't power up. While your first instinct may be to panic there are things to do if your computer displays no video. This can affect virtually every type of computer both Portable Computers and Desktop Computers. But the bottom line is if your computer won't display video, you will have to troubleshoot it. Please keep in mind that although your computer may display similar symptoms that prevent it from turning on, this article discusses what to do only if the computer won't display video, meaning the following symptoms happen when you press the power button:



• You may hear a startup chime


•  You may hear fan or drive noise


•  You may see the power light on the computer light up

If your computer does not turn on, when you press the power button:

What is lsass.exe and what should I do about it?

Local Security Authority Subsystem Service (LSASS), is a process in Microsoft Windows operating systems that is responsible for enforcing any of the security policy on the system. It verifies users logging on to a Windows computer or server, handles any password changes, and creates access tokens. Lsass.exe (the working program of LSASS) also writes to the Windows Security Log.

Perhaps the most common and important task that lsass.exe oversees is the access to the computer or server. Lsass.exe recognizes any restrictions on access to any information on the hard drive or the server, and will make sure that only recognized access codes or other login credentials will allow persons to interact with those data files. This means that lsass.exe comes into play each time someone logs into the server, or uses a desktop computer and gains access to password protected files. Forcible termination of the lsass.exe will result in the Welcome screen losing its accounts. Lsass.exe can also allow administrators or any user that is granted the proper privileges to make changes and updates to passwords and user profiles. For example, it is through lsass.exe that any authorized personnel may delete, change, or create new passwords and user files. Any and all changes that are made are noted in the Windows Security Log. This will prompt a restart of the machine; therefore lsass.exe should not be considered the Sasser worm.

How do I backup my PC

Anyone who owns a computer has heard how important it is to backup your PC otherwise known as your personal computer. When you make a backup of your PC or the files on your PC you are keeping that information safe in a place other than your computer. If your PC would ever crash or those files become corrupted the backup will help you to restore the files you need or want.

There are different ways to backup your PC. You can backup your files by burning them onto a CD or simply putting them on a memory stick. You can also backup your PC on your own time schedule.

It doesn't matter whether you have Windows, Linux, or a Mac you will be able to find information on the internet on how to back up each operating system. There is also plenty of software available that is specifically made for backup on a PC. Most of this software will guide you through the process of backing up your data and other pertinent information. There is free software you can use for backup and some you can pay for.

Best registry cleaner

Your Windows registry is considered to be an integral part of your computer. Many people do not realize that if their computer ever freezes, crashes, shows errors, does not load applications, has a "blue screen" error, or even runs slower than before, there's a very good chance that they need their system registry cleaned. Unfortunately, fixing your registry can be a difficult task, (which should only be undertaken by a professional). It is important to know that just one tiny mistake can cause a permanent, irreparable error on your PC which would require a complete reformat.

But the good news is that you do not need to take your PC back to the store for expensive repair bills just yet! Now you can use specialized software known as "registry cleaners" which can safely detect registry errors and repair them automatically. There are several Registry Cleaner Reviews. You can consult the registry and compare products so you are sure to find the right application for you. Computer experts do recommend checking the date of the registry since new products are introduced all the time. Below you will find a review of some of the most popular registry cleaners. Here is what you need to know about finding the best registry cleaner:

How can I access a Remote Desktop on XP Professional

There are two versions of Windows XP, XP Professional and XP Home Edition. The two editions are a little bit different than each other. When it comes to Remote Desktop, both versions have Remote Assistance. This is used as support technology to assist the help desk or the system administrator to remotely connect to a particular desktop for troubleshooting purposes. Only XP Professional can be the server with Remote Desktop and XP Home can only act as the "client."

What is a Remote Desktop

A remote desktop may sound confusing, but the explanation of what a remote desktop actually is is actually quite simple. A remote desktop allows a person to control the entire contents of a desktop of a computer from a whole other machine. To do this a person just needs a software application. This software application turns one computer into the manager of one or several other computers.

Do I need a registry cleaner?

If you want your computer to run better then yes you do need a registry cleaner. Your computer will run better if you occasionally clean your Windows system registry. However, if you do not know what you are doing you should not use a registry cleaner, ever.

The Windows registry is supposed to keep track of all your Windows settings including the hardware configuration, user preferences, file association, system policies, and installed software. The Windows registry is then the database in which Windows can keep track of the relationships between the hardware, software and the operating system of your computer.
Problems with your registry can make a Windows system slower, less reliable, and unbootable. In extreme cases it can only be fixed by reinstalling the whole operating system. Because of these problems that can arise from your Windows registry it is a really good idea to have a registry cleaner.

Cleaning up your computer for better performance

If you want your computer to run as quickly and efficiently as possible, it's important to clean your computer up every once in awhile. This includes deleting old files, running virus scans, and freeing up disk space.

The following are some ways you can clean up your computer for better performance.

Install a virus checker and use it regularly.
A virus checker, such as Norton or McAfee, can keep your computer safe from viruses and other things that could harm the files and other things on your computer, increasing your computer's performance. While most of these run automatically on your computer to scan for threats and viruses, you should run a scan at least once a week.

How to choose the right amount of computer memory for your business needs

Wondering how much memory you need for your computer, your laptop, or your iPod? How much memory do I need for computer, iPod, laptop, etc.? Determining the amount of memory that you need for any of your electronic devices depends on what you will be using your computer for and the type of computer or electronic device that you need.

How to choose the right desktop computer

Shopping for a desk top computer can be daunting. With so many things to take into consideration, it's difficult to know how to find the right computer to fit your needs.

Touch screen monitors

A touch screen is a device that allows users to operate a PC by touching the display screen. Touch input is fitting for a wide variety of computing applications. A touch screen can be used with most PC systems as easily as other input devices such as touch pads. Touch screen monitors have grown to be not only highly accessible, but also very convenient.

How does it work?
A touch screen has three main parts: a touch sensor, a controller, and a software driver. The touch screen is an input device, so it needs to be joined with a display and a PC or other device to make a complete touch system. Here are the main functions of the touch sensor, a controller, and software driver:

A touch screen sensor is a clear glass panel with a touch response surface. The touch sensor or panel is placed over a display screen so that the responsive area of the panel covers the viewable area of the screen. There are several different touch sensor technologies on the market and each use a different method to detect touch input.

The controller is a small PC card that connects between the touch sensor and the PC. It takes the information from the touch sensor and translates it into information that the PC can understand.

The benefits of micros systems for restaurants

Micros systems have been around since 1977. In recent years, though, they have become increasingly used in restaurants. There are many benefits of micros systems for restaurants, which make them a great asset to any restaurant, no matter how big or small.

One of the key benefits to micros systems in restaurants is that they are fairly easy to learn and use. The micros systems are mostly touchscreen computers. Generally, touchscreen computers are more accessible, allowing users of every skill and knowledge level to use them. The touchscreen, because it is fairly simple to use, will probably require less employee training since it, in a way, walks the user through the various services offered by the system.

Their straightforward design allows workers in a restaurant to see and point at exactly what they want. For example, a server can easily place an order to be sent back to the kitchen. The server finds the ordered item on the computer and touches the screen. This will usually bring up another screen or menu, asking for specifics (like quantity or if some part or ingredient needs to be omitted or if extra is wanted). Not only does the touchscreen micros system make this easy, but it can also be done quickly. Just a few touches here and there and the order is sent.

Should you go to digitized docs?

Companies make sure to backup their digital information regularly, but often they just store their paper documents in storage boxes or clunky, metal filing cabinets. However, in many cases, these printed documents can be just as important as anything on your computer. Usually, the papers in filing cabinets or storage have important signatures on them - which is reason enough to digitize your documents. Depending on what your business has stored, how many important printed documents you have, you should consider whether or not you should digitize your docs.

Storing important paper documents in a box has its disadvantages. First of all, it's not convenient. You may have a sort of filing system (though, for most people, that means a date or some identifying word written on the outside in maker), but sometimes it can be difficult to get to or sort through. Even if you have an organized filing cabinet, it still takes up unnecessary space. A stack of CD's takes up a lot less space. With digitized docs, once you have the information scanned into your computer and possibly burned onto a CD, then you can organize the documents in an orderly way that is easy to access.

Executing data migration in a cost effective way

Data migration is something that companies will have to do at some time. There are many challenges and factors that go into data migration and how it is done. Because it can be quite a time-consuming and sometimes overwhelming process, the cost of data migration can be high. However, once these challenges of data migration are understood, companies and organizations will do a better job executing data migration in a cost effective way.

Before understanding the challenges companies face when undertaking such a task, it important to have a clear understanding of what data migration entails. Data migration is, to put it simply, the transferring of data to a different computer, format, or system. This is typically done with programming, however it is also sometimes done manually (if someone does do your data migration manually, expect a hefty pricetag due to the tedious nature of the job and the long hours).

Best computer screens to improve your employee health

When choosing the best computer screens to improve your employee health, there are certain factors to consider. By choosing the right computer screens for your business, your employees will be more productive, instead of suffering from eye strain and eye fatigue.

Some of the factors to consider include the size of the monitor, the type or shape of it, and the way it performs. If these factors are not paid attention to, business owners may face unhappy, unproductive employees and rising health care costs required to help such eye strain and fatigue. It is really in the best interest of the business to find the best possible screens for their employees.

The size of the monitor is an important factor in choosing the best computer screen for employee eye health. If the screen is too small, the font on the computer will be also. This leads to a lot of squinting or it may lead to the employee getting too close to the screen in order to see better. Both can lead to eye strain and dryness - even minor eye strain can affect an employees ability to work. Constantly rubbing at one's eyes, putting in eye drops, and taking longer breaks from the computer not only is distracting, but it affects the quality and quantity of their work.
