Windows 10 has gone into restricted use mode
 

After the latest update, my Windows 10 has disabled some features, requiring activation. I haven't had such problems before. Is this something temporary or do I need to buy a new key?

I had a similar story, after updating Windows 10 the system lost activation. I tried the usual methods, checked if the old key was saved somewhere, rebooted the system, but nothing helped. Then I started looking for a solution, and many advised using windows 10 kms activator. I decided to try, since I did not want to buy a new key, installed the activator and the system worked again without restrictions.

I’ve heard a lot of people mention activators in these kinds of situations, they seem to be a go-to for many when all else fails. It’s always a good idea to double-check the source and ensure your system stays secure. Hopefully, your Windows stays stable now, and you don’t run into any more activation issues.
