Windows 10: Why are Shift + Ctrl + Alt keys not working?

One day the 'shift and alt' key stopped working on my laptop keyboard. Then, the 'ctrl' key stopped'. I connected an external keyboard, and the 'shift' key works but the 'alt and ctrl' keys don't work. Also, while reading other posts about using the 'Windows key' + a letter e.g. Q, X, R, the 'Windows key' no longer works. I tried uninstalling the keyboard via Device Manager, Sticky Keys is off, and ran a few other troubleshooting tips. Any ideas??? I am running Windows 11 and all updates are current.

CTRL+SHIFT+8 and some others not working

Okay thanks. Didn't know that tool.
It does list Ctrl+Shift+, 3 & 8. But it doesn't say what they're registered to. (And nothing seems to happen when I press them.)

The tool turns up a very short list, by the way, compared to the screenshots on that site. Just these three plus:
Hot Key : Alt+Ctrl+Delete
Hot Key : Alt+Ctrl+J (I know what this is from)
Hot Key : Alt+Ctrl+K (Kindle)
Hot Key : Alt+F4

 

Ctrl Shift Win Alt keys not working

Hi,

Just as the title suggests my shift, ctrl, win alt keys are not working. I have tried turning off sticky keys and other solutions online but the issue remains the same. This is the second time it happened, the first time was resolved when I had a BIOS firmware update but now this also didn't work.

RD Client app broken since Windows 10 Anniversary Update: Shift, Ctrl, and Alt keys not working

I was using the Windows RD Client (App Store version) with Windows 10 uneventfully with perfect functionality right up until the Anniversary Update automatically installed on my machine about a week ago. Now, the Shift, Ctrl, and Alt keys do not work properly
anymore within the remote desktop window. The keys all work fine on my local machine/desktop so it's not a hardware issue.

Here are the detailed behaviors of the various meta keys:

• The Shift and Ctrl keys don't work with the RD client window maximized, but the Alt key does work (- Shift, - Ctrl, + Alt)

• In full-screen mode the Shift, Ctrl, and Alt keys behave the same as when the window is maximized (- Shift, - Ctrl, + Alt)
• The Shift and Ctrl keys do work when the RD client window isn't maximized, but the Alt key doesn't work (+ Shift, + Ctrl, - Alt)
  
• Most bizarrely, if the window isn't maximized, but I drag the side window edges to make the window almost as wide as the screen, it starts to behave as if the window were maximized (- Shift, - Ctrl, +Alt) when both window side edges get close to the side
  screen edges. The same does not happen, however, when I drag the top and bottom window edges up and down, respectively, to make the window as tall as possible.

I need to use the RD Client almost daily for work so this is extremely annoying and affects productivity. I see that I am not the first to report this issue. Is this issue being looked into for a permanent fix rather than the poor workaround solution of
having to alternate maximizing and restoring the window depending on which meta key I need to use? Is uninstalling the Anniversary Update an option, or will it just keep being reinstalled?
