Alt key seems to get stuck since latest update (19042.985)

Hello @ricecrispies,

Since the latest Windows update (build 19042.985, version number 20H2) yesterday, I have had the same problem happen on two different computers. In both cases, the Alt key seems to get stuck so that, for instance, when I press Esc, I end up cycling through my windows and when I press Backspace, deleted characters are restored. Locking and then unlocking the screen seems to fix it, but I'm wondering what's going on because it's a bit annoying.

First of all, can you please provide the following information . . .

 System Specifications - Quick Information for Posting

I wrote this to run in CMD Prompt.

Copy & Paste the below command into the CMD Prompt and press <Enter>. It's very quick, post the results . . .

Code:

PowerShell Get-ComputerInfo ^| select OsName, WindowsProductName, WindowsEditionId, WindowsVersion, OsVersion, OsBuildNumber, OsHardwareAbstractionLayer, CsSystemType, OsLocale

These results are from an old machine I have to give you an idea . . .

Code:

OsName                     : Microsoft Windows 10 Pro
WindowsProductName         : Windows 10 Pro
WindowsEditionId           : Professional
WindowsVersion             : 1909
OsVersion                  : 10.0.18363
OsBuildNumber              : 18363
OsHardwareAbstractionLayer : 10.0.18362.387
CsSystemType               : x64-based PC
OsLocale                   : en-GB

Thanks.

Hello @ricecrispies,

Are there ANY Yellow triangles in the Device Manager => Control Panel > Device Manager?

Strange that the problem is on BOTH computers, which means it is more likely to be a OS problem [ WU ] as opposed to a Hardware problem though. There is also this option if you are unable to find an answer . . .

I hope this helps.

Thanks for your responses so far. For some reason it seems to have stopped happening. If it happens again, I'll go through the procedures you have recommended and paste the results.

I've checked in Device Manager and there are no yellow triangles.

That is typical computers for you!

By all means come back if the problem reoccurs.
