Windows 11 activation

[SaltedCream]

So I had been using a genuine copy of windows 10 on my PC without entering a product key. I have recently updated my system to Windows 11, and it shows that the OS is activated. I tried the run commads and found out that it has been activated with a KMS license which will expire after 45 days. My question is how did windows get activated in the first place without my permission; is it like a trial period or something? Will I be able to run my PC after the expiration of the license?

As far as I remember, I was using one a couple of years back, but since then I've compeletely changed my CPU, Motherboard, Ram and also did a fresh install of windows 10 which was an unactivated one.
