One of our Windows 2003 servers has a fairly small C-partition, which is approaching full. I've had a quick look round using [Disktective](http://www.disktective.com/) as to where the space has gone, and a fair bit of it seems to be taken up with `C:\WINDOWS\SoftwareDistribution\Download`

I think this folder is used as a temporary storage for Windows Update, but as all the pending Windows updates have now been installed, is it OK to delete the contents of this folder?
