Windons independently began to go into reboot. What to do?

Question

Windows

Install a new build of Windows now
Your build of Windows has expired, so your PC will restart regularly after a few hours and stop starting at some point. More information can be found online.

Today when I played, the Windows started to swear, I thought so be it. It turned out he wasn’t joking, went into a reboot during the game, oh, and then I cursed #windowsball
How is it treated? Will a fresh install help?

Answer 1

Alas). Update to new build

Answer 2

Such an error with an expired or failed activation. As advised by SyavaSyava - install the official release. Or "activate" the existing version.
