I'm in agreement with dodgecity Maybe you've got a "stuck" folder or system file which will refuse to work. But will report "working Ok" despite checks

I get these too.
How to get them right?
Couple of options open to you...
Run a System file check or a error check (chkdsk)on your Hard drive ,just type "chkdsk" in the Start Run box press "OK" it stops at a file click to fix it(I think thats the way?

rusty on it XP does it automatically)
also type "Cleanmgr" in the same box to run the Window Cleanup program .
Alternatively go to
www.ccleaner.com download the program run it tick all the boxes less the Cookies,History files on the first check list press "Analyse" then "Run cleaner" after it display the results next click the
"Issues" icon..then click the "scan for issues">"Run cleaner" buttons in that order and delete all the findings (finds an awful lot more than the Windows Cleaner)

These are Registry items which are redundant or pointing nowhere (quite safe)
This program frees up a lot of space

I think it might clear the "block"
Your computer will run faster after running this Like a mini Defrag...Though I found if I do a Defrag afterwards, it takes a lot less time than it normally does Does not have to move as much files about.Jobs done for it already
