Hi Thomas Cherry,
Thank you for reaching out to Microsoft Q&A forum. I understand how concerning it can be when your Surface Pro is locked, especially if you suspect a hacking attempt.
To assist you better, could you please share the exact error message or code displayed on your screen? This will help us identify the issue and provide the most accurate solution.
In the meantime, here are some steps you can try for each situation:
If you are still able to log in to your surface, start by running a security scan. Go to Settings (Windows logo key + I) > Privacy & security > Windows Security > Virus & threat protection > Quick Scan to check for any threats. Once that’s done, make sure Windows and your apps are fully updated. I also recommend changing your passwords and turning on Two-Factor Authentication (2FA) for extra protection.
If you cannot access your device, first disconnect from Wi-Fi to prevent any further unauthorized activity. Next, restart the device in Safe Mode by holding Shift while selecting Restart, then choose Troubleshoot > Advanced options > Startup Settings > Restart > Safe Mode. Once in Safe Mode, run a full malware scan to remove any potential threats.
Please reply with the error details or let me know if you need help with any of these steps. I'm here to support.
