Hi All: Windows 7 sent out an update in October which I just became aware of....Disk Cleanup Wizard addon lets users delete outdated Windows updates on Windows 7 SP1. I was doing a routine "disk cleanup" and discovered that when I ran it a second time and selected the "clean-up system files" tab, that it listed over 4 GBs of obsolete Windows updates that could be cleaned up! That's a pretty good hunk of space to put back to use. I then checked on all my Win7 pc's and all had over 4 GBs of old windows updates that could be removed. To see the Microsoft site article go to: http://support.microsoft.com/kb/2852386
Sounds like this could be especially useful for people who use a SSD as their system drive. While 4GB may not matter when using a modern hard drive, it is still a substantial chunk of space relative to the size of most SSDs.
