A. To disable EFS, perform the following steps:

  1. Start a registry editor (e.g., regedit.exe).
  2. Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EFS subkey.
  3. From the Edit menu, select New, DWORD Value.
  4. Enter a name of EfsConfiguration and press Enter.
  5. Double-click the new value, set it to 1 to disable EFS, then click OK.
  6. Close the registry editor.
  7. Reboot the machine.

This change will affect all users: When users try to encrypt a file, they'll receive an error. You can set the registry value to 0 to enable EFS, but this value doesn't exist by default.
