Windows 10: Keyboard CTRL+ALT+DEL not working after Windows 10 2004 update

Dear Microsoft Community,

I have been using an ASUS X55U6R laptop for the last 4 years. Until the last update everything was fine. After Windows 10 2004 update the keyboard is not responding for combination of Keys. For e.g Ctrl+Alt+Del is not working. Single key is working fine. For e.g. Alt Tab, Alt F4, Ctrl C, Ctrl V is working. I have tried all the troubleshooting options including downgrading the OS to 1903, upgrading the BIOS to 316 version, Keyboard checked, Keyboard drivers are updated, Intel chipset drivers are updated etc. But still the problem is not solved.

I am worried that the Windows 10 2004 update has affected the chipset. Kindly let me know if there is a way to solve the issue. Please do not send automated links to troubleshoot the keyboard problem because all the options are tried and done as mentioned earlier. I am not sure why Microsoft would release an update which would affect the system.

Kindly let me know the solution for this issue at the earliest.


Regards

Amit

Ctrl Alt Del, Vista

On a domain you won't get Task Manager when you hit Ctrl+Alt+Del. You get a crazy screen with a bunch of options.

Ctrl+Shift+Esc has always brought up just the Task Manager, even back to Windows XP days. You just weren't aware of it. *Wink

Go ahead, try it in Windows XP too.

 

Ctrl Alt Del, Vista

The whole Ctrl+Shift+Esc should be used to get that crazy screen with those options and Ctrl+Alt+Del should bring up TM.

Okay first of all.

It is DEFINITELY not a RAM problem. I have 16GB. The operating system is running in the background and is responding when I press CTRL + ALT + DEL, cause you can see the circle next to the cursor. The cursor responds as well..

Second, some people suggested me to use CTRL + SHIFT + ESC, I have not tried, but I will. Also this is not my problem. My problem is that the CTRL ALT DEL menu among which you can chose to turn on the task manager gives me black screen. Alt tabbing does not work with ANY software that is frozen in fullscreen, but that is normal.

On windows 7 this was not an issue. When nothing worked, ctrl alt del always worked.

On windows 10, CTRL alt deleting does not work, with some full screen applications.
