Windows 10: The two Alt keys don't work in combinations

Hi, I would like to solve this annoying windows prank windows 10 in my case

The two Alt keys no longer work for me in "custom combinations" of keys and not even in ctrl-alt-del.

- I have no virus
- the right Alt key works in the combination of special characters @#][
- the left Alt key works in combination with F4 etc.
- the left Alt key works in combination with the letters for the virtual click of the applications menu items
- the left Alt key works in combination with the numeric keypad keys for special characters
- as an alternative to crtl-alt-del i use ctrl-shift-esc and i access the task manager without problems
- if I use the "on-screen keyboard" of windows I can access the "custom combinations" and the ctrl-alt-del

as I repeat, the two Alt keys physically pressed no longer work only in the ctrl-alt-del and "custom combinations"

I have done many tests suggested by various google results and, moreover, currently, as soon as I start windows and using the Alt keys, only for the first time after switching on they emit a "whistle" from windows, this as surely result of one of the tests.

Key combinations not working

Thanks for following up. In here, you can find the list of all the keyboard shortcuts in Windows 10. Check it out and
see which key combinations are still working on Windows 10, and which are not.

We also tested on our end and only the Alt + F and Alt + P are working fine, and this is on a PC that is on the Fall Creators Update. May we suggest that you update your operating system to 1709 and see if the key combinations will work.

We'll keep an eye out to your response.

 

Key combinations not working

Yes it is supposed to work, but the combination of keys I listed are completely unresponsive. When I physically click the 'View' tab, then try to use the Alt+P combination, I get a windows noise and nothing happens.

So while I have the View menu already open, I get a sound. But in ALL other circumstances across all applications or none at all, those combinations simply don't recognise as being pressed.

If I could upload a video to show you, I would.
