The Windows Registry Editor (Regedit) is a graphical tool in the Windows operating system that allows authorized users to view the Windows registry and make changes.

Step 1. Connect your pen drive to your computer.

Step 2. Press Windows + R keys and bring up the Run box. Type "regedit" in the empty box and hit Enter.

Step 5. Check whether there is a key named "Storage Device Policies" to change the digit in the "DWORD value" box into "0" and press "OK" to save the change. 

Note: if you cannot find the key named "Storage Device Policies", you are supposed to create one: right-click "Control" to create a new key and name it as "Storage Device Policies"=> right-click this new key to open "DWORD Value" and name it as "write protect"=> Double click it to change the number.
