Windows 11 24H2 killed keyboards

Hello, Jay Eversman

Welcome to the Microsoft Community.

Thank you very much for your feedback. I have carefully read the information and problem description you provided. You mentioned that after updating to 24H2, your computer no longer works when connected to the keyboard.

I understand the trouble this problem causes you. I noticed that you have tried many methods, but the problem still persists, which is indeed frustrating.

I noticed that you have tried three ways to connect the keyboard and tried to reinstall Windows, but the keyboard still does not work. This may mean that you need to restore the system or uninstall the update to fix the problem. This may be a compatibility issue with the latest system version.

I suggest you try the following method to perform the above operations.

After three consecutive forced restarts (holding down the power button until the computer shuts down during Windows startup), the system will automatically enter WinRE.

After entering WinRE, you will see a selection screen.

Select the Troubleshoot option.

In the Troubleshoot interface, select Advanced options.

In Advanced options, select System Restore. This will start the system restore function.

The system restore tool will display the available restore points. Select a restore point with a date before the problem occurred.

Click Next and follow the prompts to complete the restore process.

At the same time, you can also try to uninstall the update to test whether the black screen problem still exists. The steps are as follows.

In Advanced Options, select Uninstall Updates.

You will see two options: Uninstall the latest quality update and Uninstall the latest feature update.

If you choose Uninstall the latest quality update, the system will roll back to the state before the last quality update was installed.

If you choose Uninstall the latest feature update, the system will roll back to the version before the feature update.

Best regards

Hi, I hope I can help you all with this response.

None of the solutions offered here will work for you although, this one might.

Assuming your mouse is still working, plug the keyboard into any free USB port.

Right click on the Windows Start Button and left click on device manager.

Left click on the arrow along side Keyboards and you should see an 'unknown device' that has issues.

Right Click on the 'Unknown device' and left click on 'Update Driver'.

Select, Browse my Computer for Drivers'.

Select, 'Let me pick from a list of available drivers on my computer'

Select 'HID Keyboard' from the list of Compatible hardware and click Next.

Allow the driver to install then retest keyboard.

You will probably have to repeat this same process for all USB ports on the front and back of your computer.

Best of luck.

Hello Michael,

The problem you are experiencing is not related to this thread. Keyboards normally fail with keys in a diagonal pattern. I would suggest that this is just coincidence if the fault followed Microsoft update.

I would recommend that you borrow a USB Keyboard and plug it into the laptop. If all keys function correctly then, you need to obtain a new Keyboard or Keyboard with Palmrest for your laptop.

I hope this is helpful.

Hello Brian,

I don't believe that anything from the users can help, as the problem is clearly due to a BUG in Win11 24H2 !

I use an old Microsoft Internet Keyboard (Standard PS/2 keyboard) connected with USB using Microsoft driver 10.0.26100.1882.

No problem since about 20 years in Windows 7/8/8.1/10/11, neither with standard keyboard layouts (DE-CH, FR-CH) nor with my own keyboard layout based on DE-CH with multiple additional symbols (Microsoft Keyboard Layout Creator Version 1.4).

Since Win11Pro×64 24H2, the first two standard keyboards still work, but the latter produces garbage when entering textboxes with the mouse, especially in the browser (Firefox) or in Microsoft Office 2019 Pro (Access). Garbage means that additional special characters appear when I type a first character into the textbox.

For example, after creating a new empty record in an Access form (only with mouse clicks and vba), the cursor being in the first textbox by default:

- when I type 'a' , I get 'Гa'  (U+0413 U+00E1); Г is coded by typing [

- when I type 'v' , I get '↕' (U+2195); ↕ is coded by typing [

- and so on… (my modified keyboard layout uses

This suggests that at this point, the keyboard buffer contains some data (likely

Private Sub NewRecord_Click()
DoCmd.GoToRecord , , A_NEWREC
SendKeys "{BACKSPACE}"
End Sub

After the additional command SendKeys, I get correctly 'a' or 'v'.

This proves that the keyboard buffer is indeed not empty. Mouse clicks obviously affect the keyboard buffer.

Independently from what happens or not upon typing the first character, the next ones always follow normally.

Just in case this could help, please note that for my particular keyboard layout, GetKeyboardLayoutList returns the negative pointer value '-255850489' (Hex value FFFFFFFFF0C00807).

This makes it impossible to switch keyboard layout programatically as usual according to their Hex value; instead, I have to use the pointers themselves (what works perfectly for both positive and negative pointers):

Function Tastatur() As LongPtr
Tastatur = GetKeyboardLayout(ByVal 0&)
End Function

…
Call ActivateKeyboardLayout(Tastatur, True) ' e.g. Tastatur = -255850489

I suspect that the keyboard buffer is likely insufficiently protected in 24H2 – or maybe just not large enough for all keyboards. If you have any means to contact Microsoft, please forward this info to them.

Best regards, Henri

Please note that the keyboard bug is not related to the latest Office version: I use an Office version elder than Win11 24H2 because of the latest Office version's crazy bug that Form_MouseWheel() always returns 0. The keyboard bug also happens not only in Access but in the browser, too.

I have three Lenovo E580s, and since upgrading to 24H2 the keyboard doesn't respond at all in Windows from a cold boot. If I then restart using the mouse, the keyboard will then work.

Very strange, but it's definitely down to 24H2.

Thanks, this confirms that the bug is indeed due to W11_24H2, not to my hardware.

My PC ist self-assembled from high quality components: Intel i7-10700 2.9GHz processor and ASUS TUF GAMING Z490-PLUS mainboard. Only the keyboard is a simple, old Microsoft Internet Keyboard (PS/2 standard).

I would immediately restore the previous W11_23H2 if I had been satisfied with it. However, it was buggy, too: awaking from sleep or even from screen off required almost (!) each time

Unfortunately the problem does come back but updating the device driver as previously stated, should resolve issue.

I would check to make sure you are running the latest Motherboard BIOS version and chipset drivers.

I think this is another Microsoft 'roll it out and wait for the flack' scenario. We could be waiting a while for a permanent fix.

Rawly's problem is different from mine, which is clearly a 24H2 bug: when entering a form, the keyboard buffer is not empty but contains

I could resolve the problem by moving the dead key to

I had exactly the same problem on my laptop, my keyboard didn't work in windows, but it worked in the BIOS, so I knew the keyboard was not broken.

I tried everything i found on the internet... regedit, game mode, filter etc.... nothing worked until I restablished to WINDOWS 23H2.... I hope they can fix it because i tried everything
