Hi Bob,
Thank you for posting on the Microsoft Q&A Forum and sharing the details. I understand that you're encountering the issue where your keyboard freezes at the Lock screen after powering on, but works fine after a restart.
Instead of restarting your computer, you can click the Ease of Access icon on the Lock screen and use the On-Screen Keyboard to sign in.
Then you can try the steps below to resolve this issue:
- Go to Control Panel → Power Options → Choose what the power buttons do
- Click Change settings that are currently unavailable
- Uncheck Turn on fast startup
- Save changes and shut down your PC to test.
I look forward to receiving your update. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
