RC 1 small problems with disk cleaner and shortcut hotkeys

DEP (Data Execution Prevention) shuts down cleanmgr.exe if I attempt to run
it on drive C. It runs fine on my USB harddrive. I thought it might be
problems with the disk so ran scandisk and it did find minor errors and
fixed them, but it made no difference. The box about DEP comes up and says
I can deactivate it for programs that are not compatible; however, this
Windows app should be compatible. Anyone have any ideas. Is this a bug?

I find that ccleaner.exe 1.33, which I was using on XP was not disabled so
it apparently runs, but it doesn't seem to be as effective as before. Have
cookies and stuff moved on Vista?
