unable to access drive access is denied

1. start -> run
2. type regedit to open registry
3. go to HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\MountPoint2\
4 now you can see keys like
{4bdd4abb-fe4b-11d5-8453-806d6172696f}
{4bdd4abe-fe4b-11d5-8453-806d6172696f}
5. if you see any sub folder in it like Shell
6. delete Shell folder
7. now open windows explorer and double click on your d or e drive
8. enjoy...


I don't have any knowledge on this stuff but as for my problem, I could solve by doing this:

1. Follow all the steps given
2. then right click on "MountPoints2"....go to "permissions..." in which u find a list in "group or username"
3. check on "deny" "full control" for each and every name (including the administrator)....
4. exit regedit.
5. now this problem should not persist even after restart i guess...
