How To Clear Windows 7 Cache

From the technical point of view there are three types of caches in Windows 7, which you can flush easily – Memory Cache, DNS Cache, and Thumbnails Cache. Clearing the Memory Cache can free up some system memory, clearing the Thumbnail Cache can free up space in your hard disk, and clearing the DNS Cache can fix your internet connection problem.

You can also clear Internet Explorer 8 Cache, but it not part of Windows 7 by default in Europe.
