Solution 2. Open Regedit and Change Registry Key

Directly jump to the second solution when you found no switch at all on the flash disk. This way is somewhat harder and needs to be done carefully.

  • Press Windows + R keys at the same time to open the Run box. Type regedit and click "OK".
  • Now, you've opened the "Registry Editor". Find the path there: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies
