| Data type | Range | Default value |
|---|---|---|
| REG_DWORD | 0 | 1 | 0 |
Prevents users from locking the system.
This entry stores the setting of the Disable Lock Computer Group Policy. Group Policy adds this entry to the registry with a value of 1 when you enable the policy. If you disable the policy or set it to Not configured, Group Policy deletes the entry from the registry and the system behaves as though the value is 0.
| Value | Meaning |
|---|---|
| 0 (or not in registry) | The policy is disabled or not configured. Users can lock the computer. |
| 1 | The policy is enabled. Users cannot lock the computer. |
While locked, the desktop is hidden and the system cannot be used. Only the user who locked the system or the system administrator can unlock it.
To change the value of this entry, use Group Policy. This entry corresponds to the Disable Lock Computer policy (User Configuration\Administrative Templates\System\Logon/Logoff).
Tip
To lock a computer without configuring a policy, press Ctrl+Alt+Delete, and then click Lock Computer.
