Windows 8.1 asking for activation key?

Hello,

My Windows 8.1 PC is asking for an activation key when I have already put it in a few months ago?

I turned on my PC, and it booted up normally, I knew it was activated as the Start screen was changed, but when I went to change my desktop background the PC restarted and now it wants me to activate windows?

Any suggestions on what to do?

Thanks,

Ryan
