I came across this nice update released for Windows 7 SP1: http://support.microsoft.com/kb/2852386 that adds the ability to Windows 7 (like Windows 8) to delete outdated/superseded Windows updates by using a new option in the Disk Cleanup wizard.

Edit: Looks like MagicAndre knows about it already: http://blogs.technet.com/b/askpfeplat/archive/2013/10/07/breaking-news-reduce-the-size-of-the-winsxs-directory-and-free-up-disk-space-with-a-new-update-for-windows-7-sp1-clients.aspx

Its interesting. I just hope that it works well enough and doesn't cause any problems that can't be easily reverted.

yes, I already know this

And it has bugs and doesn't compress WinSxS like Win8.

The latest beta version of IObit Uninstaller gets this feature too, deleting Windows updates.
