Learn More about Windows Errors

Windows errors commonly show up with the "Blue Screen of Death" but you could also get error messages on your screen. The problem is that these messages often detail files that you have never heard of. It is likely that these messages are occurring due to the registries in your system that need cleaning or other files causing a problem; files that help the everyday running of your computer.

Associated Issues with Windows Errors

Windows errors will cause problems on your computer, so it's important to save all your work. You can never be too sure when one of these errors will occur. Here are some of the more common issues that occur if you don't maintain your operating system:

  • Computer won't restart - depending on the problem, sometimes your PC will not startup. Usually a problem within the registry is connected to the booting system. This can be fixed by running the startup process through Safe Mode.
  • Programs will not work as you expected - there are times that the software will start but not run correctly. This not only gets annoying but means that you cannot use the program. Problem is that you will not always get a message saying what Windows errors have occurred.
  • Slow computer - this may be in the startup of the PC or it may be while you are trying to run processes. A slow PC can also lead to files not saving correctly, web pages timing out and other issues on your computer.

The first thing to do is see if you have any Windows updates in the lower right-hand corner. If there is a white flag popping up telling you to update, you should. Having update warnings running in the background can also make your computer slow.

Sometimes a Windows update doesn't completely install. In which case, you may want to contact their support office. This doesn't happen often, but it can be an error on their side. Windows XP experienced this several years ago.

In some cases, you might not be able to update your Windows OS because they aren't available to you. Windows XP no longer offers support, as well as some other operating systems.

It's important to note that Windows doesn't actually offer support on fixing a registry file or key. Instead, they advise to get a registry cleaner. (Even Windows admits that there are registry problems.)
