    I have download Enable_write_access_to_removable_disks_for_all_users

    Shouldn't the last line which is "Deny_Write"=-, be "Deny_Write"=dword:00000000

    When I ran it it did not create the key.

    If I run Disable_write_access_to_removable_disks_for_all_users it does create the key.

    I then changed the value from 00000001 to 00000000 and restarted Windows 10, but I still get USB is write-protected.

    Any thoughts?

    Thanks

    Hello @ctslive, and welcome to Ten Forums.

    Access to removable disks is enabled by default.

    The group policy is normally used for disabling access by adding the key and Deny_Write DWORD value set to 1.

    Deleting the DWORD is the same as setting the group policy to "Not Configured" which will allow access again.


    You have a different situation with a write protected error though. If the USB drive is failing, it can be write protected in an attempt to prevent data loss allowing you to copy the data to another drive before the drive completely fails. You might check using the tutorial below for now to see if it may help.
