Lock drives

Locking Drives:
I don’t prefer to lock our drives, but sometimes it becomes OUR Need. Say for instance you might have stored your office documents in D:\ and you don’t want your kids to access it, in such case this technique can be useful for you. Please don’t try this tweak with your root drive (usually C:\ is the root drive) since root drives are not intended to be locked because they are mandatory for the system and application programs.
* Start & Run and type Regedit to open Registry editor* Browse HKEY_CURRENT_USER\Software\M*cro$oft\Windows\Curre ntVersion\Policies\Explorer* Create a new DWORD value NoViewOnDrive and set its value as
2^ (Alpha Number of Drive Letter-1) where Alpha number are simple counting of alphabets from A to Z as 1 - 26
For example: to lock D:\, Alpha number of d is 4 so 2^ (4-1) = 6 (decimal value)
* To lock more drives, calculate the value of each drive and then set sum of those numbers as value* To unlock your drive just delete the key from theregistry.
