Welcome William Pappas,
I know how frustrating it can be when your Windows 10 desktop PC appears to be compromised and is now locked, preventing normal access.
Before proceeding further, I need to narrow this down a bit to ensure the correct guidance is provided:
- When you say “locked” do you see a Windows sign‑in screen, or a message demanding payment or instructions from an unknown source?
- Are you signing in with a Microsoft account or a local Windows account on this PC?
I look forward to your reply so we can continue working together to address the issue.
