Hello,
Thank you for posting in Q&A forum.
To resolve this problem, use another screen saver program (such as Logon.scr) that is installed locally on the system or that is not corrupted.
- Start Registry Editor (Regedt32.exe).
- Locate the Scrnsave.exe value under the following registry key: HKEY_USERS.Default\Control Panel\Desktop
- On the Edit menu, click String, type logon.scr, and then click OK.
- Locate the ScreenSaverIsSecure value.
- On the Edit menu, click String, type 0, and then click OK.
- Quit Registry Editor.
Note If you modify the registry incorrectly, you can cause serious problems. Therefore, follow these steps carefully. For additional protection, back up the registry before you modify it. For more information about how to back up and restore the registry, see How to back up and restore the registry in Windows.
I hope the information above is helpful.
Best regards
Zunhui
