Windows 10: CTRL ALT WIN and F10 keys not working

As the topic title says, my CTRL WIN ALT and F10 keys are not working. I've restated my computer, tried a different keyboard, the CMD line method that was recommend in other keyboard related issues on here, uninstalling and reinstalling my keyboard drivers but none of it worked, and when I use an online keyboard it reads those keys as left mouse clicks see image attached.System Info:Edition Windows 10 HomeVersion 22H2Installed on ‎1/‎18/‎2023OS build 19045.4894Experience Windows Feature Experience Pack 1000.19060.1000.0Processor AMD Ryzen 9 5950X 16-Core Processor 3.40 GHzInst

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.

Strange Transient Icon Results From Entering Alt-F10

I am running Win 10/Pro x64 Ver. 20H2 19042.804 The 'second' profile applies to this post.

I'm configuring a 'new' machine and experiencing unexpected behavior when I enter Alt-F10. A small transient icon, a small black box with a blue thermometer and a number (I've seen 98 and 100) appears for 2-3 seconds in the upper left corner of the display. I captured it as a Screen Dump.

I first noticed it when I tried to enter Alt-F10, the command used to configure the file manager program, ZTreeWin. See attached image.

I subsequently determined that the same behavior applies when I enter Alt-F10 and the desktop is the only display. If I select F-10 alone the thermometer has an X below.

I am using a Logitech Ergo 860 wireless keyboard with a USB dongle installed in a blue USB 3.0 port.

The Ctrl-Alt-Del does open "Lock, Switch user, Sign out, Change a password, and Task Manager," so the Alt key is working

The F-10 key alone also opens almost the same transient Icon, a black box with a 'blue thermometer' with an X at the bottom.

I tried substituting an old PS/2 keyboard but it was not recognized. Perhaps this is because it lacked drivers?

The 3 attached images to show the 'icon' I'm talking about.

Can anyone suggest a way to get an 'honest' Alt-F10 from this keyboard? My searches suggest that MS call it an 'unassigned' function key.

 

ctrl alt del to logon

Hi Diane,

Conflicts with the user account settings is one of the possible reasons why the secure sign-in option is enabled on your computer even if the box in the settings is not checked. I would suggest that you enable and disable the
Require users to press Ctrl+Alt+Delete. You can follow the steps below:

• Press the Windows key + R.
• Type control userpasswords2 or netplwiz and press the Enter key.
• Click the Advanced tab.
• Under Secure sign-in, check the Require users to press Ctrl + Alt + Delete checkbox.
• Click Apply.
• Restart your computer.
• Open the same settings again and uncheck the Require users to press Ctrl + Alt + Delete checkbox and follow the
  steps 5 and 6.
