BRUNEI - A common complaint we hear from computer users is that "my computer is slow", "it takes a while for my computer to start up", "it take ages for a file to open", and many others.
When one uses a computer over a period of time these complaints become obvious and this could be for several reasons. Mostly it is due to a virus or a malicious software running in a computer which takes up most of your computers processing power as well as other resources. At other times it could be due to low disk space, low memory, low processing power, fragmented files, and too many startup programs and services, among many others.
On the other hand there are issues such as corrupted files, computer driver software issues, and inconsistent software updates.
In Microsoft Windows 8.1 there are many built-in features to identify and troubleshoot most of these issues. Some of these features are Restore your "PC", "PC Refresh" and "PC Reset". Although Restore your PC was there in Windows 7 and earlier, the PC Refresh and PC Reset were introduced in Windows 8.
Restoring your PC is a way to undo recent system changes you've made. If there is an issue with an app software driver that was recently installed which is causing problems with your PC, you can restore back to an earlier point in time, called a "restore point". Be aware that system restore is not a replacement for computer backup. This feature is not available in Windows RT 8.1.
The PC Refresh helps a user to reinstall Windows without affecting or deleting any of the personal files or changing the system settings. It will retain all the data of the user as it is and reinstall Windows. One can use this when his computer is not performing as well as it once did and don't know why.
Resetting your PC will wipe everything in your computer and reinstall Windows. This will not retain your personal files, folders or settings. This would be similar to factory reset or a complete format of your computer and reinstallation of Windows.
All of these setting can be accessed from the PC settings window in Windows 8.1
