Dear Jill,
Thank you for your question and for sharing the details into Microsoft Q&A Forum.
I’m sorry to hear the external full‑size keyboard stopped working right after a Windows update, that can be disruptive, especially if it previously worked reliably. At this point, I recommend that you review and try the steps provided in the Independent Advisor’s answer on your thread. That reply typically include the most relevant checks for this scenario. To help narrow this down further, could you please share a few details:
- Your Windows 11 OS build (Press Win + R, type
winver). - The keyboard make/model and connection type (wired USB / wireless with USB receiver / Bluetooth).
- Your device model and if you use a USB hub/dock/adapter, its make/model too.
- In Device Manager (Keyboards / Human Interface Devices / USB controllers), do you see any Unknown device or warning icon when the keyboard is connected?
In the meantime, here are additional steps that you can try:
- Accessibility settings
- Settings > Accessibility > Keyboard
- Turn Off: Sticky Keys, Toggle Keys, and Filter Keys.
- Test typing again.
- USB power settings
- Device Manager > Universal Serial Bus controllers >For each USB Root Hub, Generic USB Hub, and USB Host Controller > Properties > Power Management > uncheck “Allow the computer to turn off this device to save power.”
- Then go to Control Panel > Power Options > Change plan settings > Change advanced power settings > USB settings > USB selective suspend > set to Disabled (for both battery & plugged‑in if applicable).
- Restart and test.
- Turn off Fast Startup
- Control Panel > Power Options > Choose what the power buttons do > Change settings that are currently unavailable
- Uncheck Turn on fast startup > Save > Restart.
- System file health check
- Open Command Prompt (run as Administrator) or Windows Terminal (run as Administrator) and run each:
sfc /scannowandDISM /Online /Cleanup-Image /RestoreHealth - Restart and test once both complete.
While my initial response may not fully resolve the issue, I truly appreciate your cooperation as we work together toward identifying the most effective solution. Thank you so much for your understanding.
I hope these checks help restore your external keyboard functionality promptly and minimize any interruption to your work. Wishing you a smooth Windows 11 experience ahead.
