Ok, so you can't access these folders ever or just after boot up(like it works later?)?
If it just started I would try using dial a fix (just run everything by pressing the green checkmarks then go) and if that doesn't work I would try a system restore.
Your saying that you can't open any folders at all right?
Humpty, I'll know for sure if your suggestion has done the trick after a few days, but so far re-checking those options has made opening folders with windows explorer a lot faster, and no hangups yet.

Sorry its been a long day.
At the end of an angst ridden day , and in the middle of a stressed out post , there was a little gem.
Dial-a-fix.
Just remembered that, and appear to have cured the problem at last by checking only "Registration Centre > Explorer/IE/OE/Shell/WMP".
