I'm guessing you got this as a outdated response from a AI chatbot as it has not been Option/Preferences for a rather long time now as it is under Settings whether on Windows, macOS, or Linux.

I cannot receive a page from the copyright office because they say I have a popup blocker preventing it. How do I find it to turn it off. It is not in the system settings when searched. Help please.

Had the same thing happen! It’s usually your browser blocking it, not Windows. If you’re using Chrome, go to Settings > Privacy & Security > Site Settings > Pop-ups and redirects, then add the copyright office site to the “Allowed” list. That should do it!
