This issue occurs when NTFS permissions management is disabled in File Explorer or blocked via Windows Registry / Group Policy.

To restore the Security tab, follow these steps:

  1. Press Win + R, type regedit, and press Enter.
  2. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer
  3. Look for a DWORD value named Nosecuritytab. If it exists, double-click it and change its value data to 0 (or delete the key entirely).
  4. (Optional) Check the same location under HKEY_LOCAL_MACHINE and set Nosecuritytab to 0.
  5. Restart File Explorer via Task Manager or reboot your PC for changes to take effect.
