That looks like a fake CAPTCHA / social-engineering scam, not a real reCAPTCHA.
Why it’s suspicious
It tells you to press Win + X, open Terminal, paste something, and press Enter.
Real CAPTCHAs do not ask you to run OS commands.
This is a common trick to get users to paste malicious commands.
What to do
Do not press any keys or paste anything.
Close the tab immediately.
If you already interacted with it:
Disconnect from the internet for a moment.
Check for suspicious downloads, browser extensions, or new apps.
Run a trusted antivirus scan.
On Windows, review:
Startup apps
Installed programs
Browser extensions
If you want to report it
You can report the site to your browser’s safe browsing / phishing reporting tool.
If this came from a link, treat the source as suspicious too.
If you want, I can also help you analyze the URL and tell you whether it looks like a phishing domain.
