Windows 10: Computer locked. Is this a scam? What should I do?

I called 888.236.0923 phone was not answered as Microsoft. I have not clicked or called any other number.

A popup scam locked up my laptop computer.

That's a fake so-called Tech Support scam alert/warning which you are seeing in your browser.

"Remember that real error messages from Microsoft, or other big tech companies, never include phone numbers for you to call them.

If your screen suddenly fills with scary pop-ups you should immediately close your browser (try pressing ALT+F4 if you can't do it with your mouse). If you can’t close your browser try restarting your computer."

Other methods to get out of such fake Tech Support scam browser warnings are listed here:: Thread "Blocked computer" page 1: _AW_'s reply on January 21, 2023

Random Auto-Locking of Computer Screen

Nobody suggested checking out Event Viewer? When your computer randomly locks, search for, and open: Event Viewer Under Windows Logs, Check out: • Application • Security, and • System See if you can find something that states anything that could be related to your computer locking. The newest events are listed at the top of each section, so finding an event log would be pretty easy to find. Hopefully we can find what is causing the computer to lock.
