When logged in as a particular user (an Administrator) on a Windows Vista machine I cannot rename new or existing folders under Windows anywhere on the system, including external USB drives, NAS etc.
When I try to rename a folder it just reverts back to its original name. No error message is displayed. No system events / errors are logged - the system event viewer shows nothing unusual.
Bizarrely I can create new folders, which simply appear as the default "New Folder". Trying to rename the folder at the time of creation just reverts back to "New Folder". I can also delete new and existing folders.
I can create/rename files OK.
This obviously causes all sorts of problems when trying to install new software. Incidentally, the user account in question is only used for installing Windows Updates and new software.
The two 'standard' users on the system can rename folders OK.
I had this exact same problem (on the same machine) a year ago. At the time the only fix that worked (I tried numerous registry fixes as I recall) was to simply create a new Administrator user and delete the old! But it has happened again.
What can cause this problem? How is it better solved?
The system appears to be virus/malware free having scanned using Avast!, Spybot Search & Destroy and Windows Defender. HijackThis does not throw up any nasties as far as I can tell either.
I can rename folders from the command prompt (cmd.exe)! It is just within Windows I can't!
As requested by @wullx... HT-logfile and running-process-list:
Exported registry-settings under HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\ 1,142KB (too big for pastebin):
UPDATE (2011-05-06): I ended up deleting the troublesome 'administrator' user account (as I did last year!) and creating a new 'administrator' account and the system now appears to be working fine. The only caveat with deleting the user account as far as I can see is that the 'standard' users on the machine have lost the majority of their desktop shortcuts. I assume the majority of these shortcuts were created as a result of installing software whilst logged in as the deleted 'administrator' account!?
