That darn WinSXS black hole!

As you may know, every Windows installation starting with Vista has a winsxs directory that takes up a lot of space... not a problem when you have a 500GB volume... but a big problem when you have a VPS with only 40GB of space and the winsxs is taking up 12GB!

Just ran across a post on that finally actually works for reducing the winsxs directory.

dism /online /cleanup-image /spsuperseded /hidesp 

I can verify that this command works Windows Server 2008R2 and Windows 7.  I don't have a Windows 8 installation yet.  

When I ran this command on my Windows VPS, the server's winsxs directory reduced from 12GB to about 8.5GB now... 

Whew... space feels good!
