HOW TO LOCK DRIVES IN WINDOWS 7,8, AND 10?

 Say for instance you might have stored your office document 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 programs.

• Start & Run and type Regedit to open Registry editor
• Brouse HKEY_CURRENT_USERSoftwareMicrosoftWindowsCurrentVersionPoliciesExplorer
• 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 look C:, Alpha number of C is 3 so 2^(3-1) = 4(decimal value)

• To lock more drives, calculate the values of each drive and then set sum of those number as value 
• To unlock your drive just delete the key from the registry.
