The temp folder found in C:WindowsTemp often contains files that have no reason to exist any longer.
You can use the ‘Disk Cleanup Wizard’ that comes with windows to sort out your temp folder by
clicking on the
Start menu -> Programs -> Accessories -> System Tools -> Disk Cleanup.
Select the drive you wish to clean (usually C:) and then after a while of loading a dialog
box will appear with options or recommendations.
Then go on make your PC faster.
