Windows 11 low fps

When you bought your laptop with Windows 10 the Key would have been imbedded into the OS. Depending on the store you purchased the laptop from you may have a sticker with the Key listed on the laptop. Once you installed the non-legal OS it would have over-written the original Key so if you cannot find it I'm afraid you're going to have to purchase one.

Well, you definitely have a non-legal copy then if you downloaded it from there.

As to "where can I download the original version of Windows 11 or windows 10 without a key": You can download Windows but, without a key, it won't be a legal copy. It sounds to me as if you want Windows but don't want to pay for it which is something we aren't allowed to discuss on here

I bought a laptop with the system (windows 10) but I don't know what the key is. I do not want to use an illegal copy, so is it possible to check the activation key somehow?

When you say you installed the system from a different person do you mean that you're using an OS that is not entirely legit? If so that's the issue you're having.

I had the original version but I wanted to install a newer version for the beta channel and I had the dev channel. So I installed it manually from youtube. in the system, however, it says that the system has been activated with the key.

Yep, that's the issue then. I'm afraid you would need to have a legal copy of the OS. Any cracked version would not be able to work as is intended as was stated above by Nursemorph

It was downloaded from youtube (Mediafire) so well .. I'd rather get rid of it. where can I download the original version of Windows 11 or windows 10 without a key because I do not know it myself (unless you can check it) On the other hand, the performance is the same everywhere except for the strange drops in FPS when moving. It seems to me that I should get fps because this is the version in which the performance of AMD processors is fixed. So back - where can I download the original version and should I download Windows 10 or Windows 11?

Sorry to hear it. I've seen others having the same issue as you are now. Please make sure that your graphics card drivers have been updated as well. If that fails you may need to try a fresh install of the OS to get it working properly
