Hi, I'm Mario, and I'd be happy to help with your issue.
We are sorry about what happened.
Perform the test:
- windows + I > Ease of Access > Keyboard
- Enable the "Sticky Key" option
- Go to any folder
- Press CTRL and release
- Press A, do not hold CTRL
*If the shortcut works it is an indication that the keyboard may be having a problem recognizing the CTRL+A keys simultaneously.
- Disable the "Sticky Key
If it doesn't work even using the sticky key:
Test reinstalling the keyboard driver.
- windows + X > Device Manager > View > Show hidden device
- Click > Keyboard
- Do the process below for all devices listed under "Keyboard
- Right click > Uninstall Device > Uninstall
- Restart your computer
Kind Regards,
Mario B.
