Windows 7 is bugged

[sombramain22]

a few months ago i brought a cheap copy of windows 7 of amazon, at first i was suspicious and thought it would be a fake, but recently check and found out its a legitimate copy of windows. However I've been having loads of weird bugs with it, like the some setting not saving or action center messages that keep popping up over and over again, just wondering if this is normal? or is my windows or PC bugged?

thanks

Windows license is a key.
Your copy may be modded, but you can always download clean windows and use your key

Have you installed it on a modern computer because new ones don't support Windows 7 very well.
