Windows cannot access the specified device, . . .

Windows Vista35
After displaying "Preparing your desktop" for quite sometimes, then

error message as below followed.



Windows cannot access the specified device, path, or file. You may not

have the appropriate permission to access the item.



I restored the backup but the same message returned. Reinstalling the

system is only way out I can think of. Is there a way to solve the

problem without reinstalling? Any suggestion will be appreciated.
