Well that's an old overused IMO tip that holds less and less weight with newer and faster computers and drives. Stop using it and you'll never miss it till you need it.

But you can tidy up your drive through Disk Cleanup...and remove all the minor restore points that have accumulated, leaving only the last point. A good practice is to create a restore point when everything is fine...then do a Disk Cleanup and remove the rest.

Another tip....Install CCleaner and use it. It cleans up everything in 1 click.

Then defrag. (I have a simple batch file I wrote that calls Windows Defrager and defrags only the partitions I specified in the file WITHOUT the Windows defrag app appearing on the desktop. This all happens in a dos box and the advantage is that I click an icon and it starts defragging immediately and closes when it's done. It's very fast this way)
