In trying to free up and clean up some space on my PC I was doing a defrag and the report listed the file Windows\Debug\UserMode\usernenv.log as not being able to be defragmented. I found the file and it is 4GB big! I looked online to see if I could delete the file, but I didn't find anyone saying it was ok to delete it. Can I actually delete this file? I guess it has a bunch of group policy info it in, but I can't even open the file in wordpad/word/etc to see what is in it. Can I delete this file w/o harming my PC, or am I just gonna have to live with it on my HD?
