How to Remove WindowsActivationError Pop-up Manually?

Hello. I have a serious computer issue. My computer has been locked by the WindowsActivationError Pop-up. Back then, I just finished installing a media player. A message popped up and said that installation was done. I clicked on “Close”. Suddenly, a window appeared and asked me to enter a product key. So, I did as it required. However, it said product key missing. To fix the problem, I was supposed to call the Windows support for help. I was not sure if it was a right choice, so I left the problem and turned off my computer, waiting to see what would happen the next day. Unfortunately, the pop-up is still there. Should I trust the support and call the number? Are they able to fix my problem? Is there a way to fix my computer without calling them? What do I do? Any advice would be appreciated.
