Windows 7: very large file in c:\windows

Windows 7 Ultimate x64
 
 
very large file in c:\windows

I noticed my C: almost filled up so I used my handy WinDirstat to figure out what happened. It looks like 10 days ago a huge file was created in my c:\windows directory. The filename looks like some HEX registry key of some sort. The curly braces are actually in the filename. I did some quick googling and didn't see anything like this. Any ideas what this could be? I tried moving it to my D: but the file is in use by "System". I'm currently at 3GB free out of 150, so I really need to clear this file out if it is not needed. I thought maybe it might be some corrupted swap file, but I have mine set to my D:

This is Windows 7 Ultimate 64bit

Go into safe mode, and rename it. Reboot normally. If your windows loads fine, then just delete the file.

I don't know what that file is either. If it was my computer I would do a little more investigation on what that file is before removing it. Do you have a duel boot? When you are sure you want to remove it send it to a c/d or dvd.

No point digging into it unless you have the time to waste. Just get rid of it.
