deny all

About this tag
The 'deny all' permission setting in Windows NTFS can lock out even administrator accounts from accessing drives or folders. Users who accidentally apply 'deny all' to system groups like 'Users' or 'Everyone' often find themselves unable to access their own data, including external hard drives. Common symptoms include missing Security tabs in drive properties and Windows reporting zero data despite files being present. Recovery methods discussed include booting into Safe Mode, taking ownership via command-line tools like takeown and icacls, or connecting the drive to another system with different permissions. These threads focus on troubleshooting and regaining access after misapplied deny permissions.
