Hi Sandra Cooper,
Thank you for reaching out to Microsoft Q&A forum. I understand how alarming this situation can feel, especially when access to your computer is blocked.
Besides, I see that some steps have already been shared, so I’ll pull them together here and add a few more recommendations:
First, let’s stop any further activity. Please disconnect the PC from the internet right away by turning off Wi‑Fi and unpluging any Ethernet cable. If the screen won’t let you click anything, hold the power button for about five seconds to shut the computer down. This is a standard first step and helps prevent the issue from spreading or getting worse.
Next, please don’t interact with the message on the screen. Don’t pay, don’t call any phone numbers, and don’t scan QR codes. Also avoid entering passwords, card details, or any personal information. These messages are designed to create panic, and paying doesn’t guarantee recovery.
Once the PC is powered off, we’ll start it in a safe, limited mode. Turn the computer on and, as Windows starts to load, hold the power button to force it off. Repeat that power‑on and force‑off cycle about three times. On the next startup, you should see Preparing Automatic Repair. From there, choose Advanced options > Troubleshoot > Startup Settings > Restart, then press F4 for Safe Mode.
While in Safe Mode, run a full security scan using Windows Security. Open Windows Security, go to Virus & threat protection, choose Scan options, and run a Full scan. If anything is found, remove or quarantine it as recommended and let the scan finish completely.
After the scan completes, restart the PC normally and check whether the lock screen is gone. If everything looks normal, you’re all set.
If the lock screen comes back or the system still doesn’t feel right, the safest option is to reset Windows. This removes anything hidden and gives you a clean system again. Go to Settings > Update & Security > Recovery > Reset this PC, choose Keep my files, then follow the prompts. This keeps your personal files but removes apps and fully cleans the system.
Please take it one step at a time and let me know how it goes or if you get stuck at any point. I'm here to help.
