      Using latest update for Windows 10. Could not find any listing in registry for “StorageDevicePoi” or anything similar. Anybody got a link to a method for fixing a microSD card that CLAIMS to be write protected and will not allow deletion of files or formatting with SDFormatter, Windows 10 formatter, or the free HP SD card formatter?

  1. None of these seem to relate to W`10…..Storage Device Poi can’t find this so is as far as can get…Help

  2. Its meant to be HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies.
    But it doesn’t exist in Windows 10.

  3. I have no such thing as “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\StorageDevicePolicies” on windows 7. It won’t let me format going through “manage drives”. Brand new device. Any ideas?

  4. Had 2 micro SD cards saying ‘write protected’. Done all I was advised to do and nothing worked until I put the micro SD cards in a different adapter and they formatted and let me copy and paste pics onto them!!! So the error was with the adapter not the SD card.

    1. Having the same issue on a new micro SD 200GB Card

      Tried everything I have found on the net and the EaseUS Partition Master software couldn’t do anything either.

  5. Click on “OK. ” Your computer will then format your SD card and remove the write-protection status from the disk.
