Does Microsoft have a fix for the common issue with laptop keyboards not working after Windows 11 Updates

Patrick Richey 30

I have had multiple laptops, multiple brands, having their keyboards stop working after doing Windows 11 Updates. So far, the only temporary fix I have found is to delete the Standard Keyboard Driver, reboot, then the keyboard will work again until the next shutdown. Then I have to repeat the process. Does anyone have a real and actual fix for this issue? I've been through dozens found with Google, none of them actually work though. I'm used to having issues in Windows and I can usually figure out a fix for them, but this one actually has me stumped! I've already updated the BIOS to the latest version, performed all the latest Windows Updates, Disabled the Filter Keys, Reinstalled the Keyboard Driver, Ran SFC and DISM, and some other things I found online. FYI, I can plug in an external USB Keyboard and it will work, even after shutting down and restarting. This has happened on HP, Dell, Lenovo, and ASUS laptops. The only common denominators I have found so far is Windows 11 and the Standard Keyboard Driver. Currently it is happening on one with a fresh install of Windows 11 Pro using the Standard 101/102-Key or Microsoft Natural PS/2 Keyboard for HP Hotkey
Support. I'm looking forward to receiving positive input on this issue.

I have noticed the same issue as of late. I have seen around 6 or so laptops, 1 AIO desktop, and recently 1 full desktop where mouse and keyboard are not working at all till we restart the computer or delete drivers then restart anyways. So far I have only seen the issue on the most up to date computers. Hopefully this issue can be investigated and we can have a concrete acknowledgement of this issue soon.

Hi Patrick Richey,

Thank you for reaching out to the Microsoft Q&A Forum! You’ve already done a lot of the right troubleshooting steps, so let’s focus on what usually resolves this issue permanently.

The behavior you described (internal keyboard stops working after Windows 11 updates, works again only after uninstalling the Standard PS/2 driver, external USB keyboard always works) points to two common causes:

Fast Startup restoring a bad driver state after shutdown.
OEM hotkey filter drivers (from HP, Dell, Lenovo, ASUS) interfering with the keyboard class in Windows.

Here is my suggested solution on what you can do to fix it:

Disable Fast Startup

Go to Settings → System → Power → Additional power settings → Choose what the power buttons do → Change settings that are currently unavailable, then uncheck “Turn on fast startup” and save.
- Or run this command in an Admin terminal: powercfg /h off
Then perform a full shutdown to test: shutdown /s /t 0

I'm having the exact same issue with 2 x Dell Laptops. I have disappeared down a number of rabbit holes with this one, including getting Dell to replace the keyboard on one of the laptops, with the issues still remaining. I've tried all the steps in the original posters comments and also turning fast startup off, none have worked!!!!!

Any other suggestions Microsoft? This definitely looks like a windows issue

reg query HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318}
reg add HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} /v UpperFilters /t REG_MULTI_SZ /d kbdclass /f
reg delete HKLM\SYSTEM\CurrentControlSet\Control\Class\{4D36E96B-E325-11CE-BFC1-08002BE10318} /v LowerFilters /f

Hi - Thanks for getting back to us. I have carried out the actions that you suggested and can confirm that the issues is still present.

Microsoft Windows [Version 10.0.26200.6901]

The operation completed successfully.

The operation completed successfully.

ERROR: The system was unable to find the specified registry key or value.

C:\Windows\System32>reg add HKLM\SYSTEM\CurrentControlSet\Services\i8042prt /v Start /t REG_DWORD /d 1 /f

The operation completed successfully.

C:\Windows\System32>powercfg /h off

After issuing the last command to shutdown, the laptop turned off and upon reboot it did actually work first time. However following a 'Sign Out' and attempt to login in again the issues was still present.

To recap the issue occurs when you turn the laptops on from being powered off. At the login screen the keyboard is unresponsive, this also occurs with external USB connected keyboards.

To get the keyboard working you have to restart the laptop at which point it will work, you can login and use the device happily. That is until you either sign out or shutdown, at which point it stops working. It is completely reproduceable.

This is happening of 2 x Dell laptops that I have, the original poster suggested that they had seen this on different vendor laptops. One of the laptops, the first that this happened on, is less than 12 months old. The other laptop is a few years old not, but this did not exhibit the issue until it recently did a windows update to 25H2. I note from the update history that the newer laptop updated around 10/10/25 which is roughly when we first saw our issue. I have tried to roll back 25H2 but this did not fix the issue.

FYI I'm experiencing exactly the same, repeatable, issue, on a Lenovo ThinkPad X1 Carbon 9th Gen.

Thank you, this seemed to resolve the issue for me on this particular laptop. I'll try it on a couple more to see if it works on them as well. I greatly appreciate your assistance.

It was helpful to run these commands from command prompt. All keys functions restored except for spacebar, spacebar key still nonfunctional.

I've had the same problem since installing a Windows update about a month ago - so I fix it, and it occurs again every time I install a windows update. I have an Acer laptop. The fix I use is - restart/go into BIOS [F2 at start] and restore system defaults [F9]/Then "Exit" Save and close. Then reboot. It works till the next Windows update.

We have been seeing the same issue on Dell and Lenovo PC's. After uninstalling the keyboard driver in Device manager, restarting the laptop it would work briely. If you restarted the laptop again it would stop working. we have even come accross the mouse failing as well.

Uninstalling update KB5066835 helped with one device. Then after a repoot issue kicked in again.

Just hope Microsoft have identified this and look to get a fix in place soon.
