Windows Explorer hangs

[PatrickECleary]

After running the gui version, I noticed that explorer windows are hanging for 10-20 seconds every time a new window opens. This includes "Save As", "Open...", and even just "Computer".

I'd be happy to do some digging on my end, but I don't really know where to start. I can't find anything egregious in the error logs... Considering this is my main machine, it's a pretty big deal for me right now.

(I know, I know... I should've done a system restore point first...)

Can somebody please help point me in the right direction to fix this?
