Blue screen says to activate windows pop up every few hours

This is how it look like :



This is in my country language but it doesn't matter (btw its says :"go to settings to activate windows"), anyway any idea how to prevent it pop up? if I don't want to activate windows...

Thanks!

You will continue to get that pop-up until you actually activate Windows. I learned about that back when installing Windows and the activation process was first introduced [several years and versions ago].

Ah ok. But any idea why when I try to open the "Activate Windows" it opening blue window for a second and close it self.

I don't think you've bought Windows in the store, do you? :/

I'm not sure what the course of events are after the grace period ends but it should allow you to input a key to activate. Something may have screwed your licensing files - have you used any piracy stuff on there?

I have this PC pretty long time and from what I remember my windows was activated before the last time I formatted it.
I have tried to use some activators to activate it back, maybe that what caused to the problem?
