Hey, I was just wondering what a WU Temp folder was and why it was on my hard drive. I've deleted it on my C: drive and my secondary (Z: ) drive, but it came back on the Z:. It's got a .cab file and a few other files in there and I have no idea what they are or where they came from. They only take up 71Kb, but I really don't like it there. I made it hidden so I wouldn't have to see it's ugly face every time I opened explorer, but I still don't want it there.

What's up with this? Any ideas on how to remove it and not make it come back?

Thanks guys

I believe the "WUTemp" folder is created by Windows Update, which it uses to copy and extract *.cab/installation files to and such (basically a working temp folder). AFAIK the temp folder should be present, but empty...in that after Windows Update installs the update(s), it deletes the installation files it's extracted. IMO, Windows Update probably just didn't clean out the folder thoroughly after completing the installation of a particular update(s). ;)

i see that folder occasionally aswell. it bugs me when programs can't clean up after themselves.
