Unexpected date change on PC with Windows 11

[Gege52]

Hi. !

Please help me. I don't understand these random date changes. The PC went to 2049 for about 3 hours, then returned to the normal date. You can see the details in the two attachments. What could have caused this date change? When the date was changed, the Microsoft 365 Pack was installed on the PC in 2049. It is still installed on this date. I noticed fraudulent attempts to access my Microsoft account. An "Unusual Account Activity" message appeared the day after the date change. Suspecting hacking, I changed my Microsoft password, but I'm still having problems with Outlook, especially with Windows files dated 2049. Could the "Unusual Account Activity" message be related to the date change? Sincerely,

First date change, from 2025 to 2049

Second date change, from 2049 to 2025
