Method 5: Edit the registry
The fifth and final step you can take is to edit the registry. As mentioned earlier, the registry is a database that stores all the settings and preferences of your operating system. If there are incorrect or corrupted registry entries that are related to Ctrl+Alt+Del, then this function may not run properly. You can edit the registry in the following ways:
- Open Run by pressing Windows R on your keyboard, then type regedit and press Enter.
- In the Registry Editor window, navigate to the following location:
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\System
- Locate and double-click on the entry named DisableTaskMgr. If this entry does not exist, then you can create it by right-clicking on a space in the right pane, then selecting New > DWORD (32-bit) Value and naming it DisableTaskMgr.
- Change the value of this entry data to 0 and click on OK.
- Close Registry Editor and restart your computer.
After your computer restarts, try pressing Ctrl+Alt+Del again and see if the problem is resolved. If not, then you may need to contact Microsoft technical support or your computer manufacturer for further assistance.
