Its usually better not to mess up with deleting these files manually, and instead leave this task to either windows disk-cleanup, or other disk cleaning tools. The one I personally use and can recommend you is the ccleaner (http://www.piriform.com/ccleaner).

CCleaner can help you automatically find obsolete files in a program and deletes them for you.
