I have folders in the root directory (c:\) of my servers that I have been told are left overs from WSUS updates. One of these folders is 8620cfccbb5c84badcf25c9c4c7c49. They are taking up huge amounts of disk space. I have them on my Windows 7 machine also and have always been able to just delete them, but these are on a Windows 2008 R2 virtual server and I don't know if the can be safely deleted. Does anyone know the answer to this question?
