Hi all,
Since last moth Windows+L stopped working. If I click start - Account and lock it doesn't work either (nothing happens).
Ctrl+alt+delete does not work either (nothing happens)
Tried to configure local group policy to disable/not configured but that doesn't help. Only thing that helps is a reboot. It will then work for a while before it stops working again.
Tried to restart Explorer.exe but that doesn't help either.
Only Windows shortcuts that is working is :
Windows+D
Windows+A
Any ideas?
thanks!

Well start with a system file check, from an admin command prompt, search start for cmd right click Command Prompt and Run as administrator, enter \ copy and past;
sfc /scannow
That will run for 30 mins or so. If it finds errors run again until it does not.
If that is clear try a clean boot see if it occurs then i.e. to rule in or out any third party software.

Hi,
According to your description, it stop working after boot for a while. It most probably caused by third-party software or services.
Please perform a Clean Boot to find the culprit:

Hi Karen,
will try safeboot, but company policy does not allow to disable Trend Micro Antivirus.
Other people in the company does not have this issue, seems like I'm the only one....

You mean you don't even see the prompt? FWIW I just noticed that before the prompt I get a message "Preparing Security Options". If your security package is interfering then you might be able to detect it using ProcMon.

I see nothing, its like keyboard is not working. Same issue if I use built in keyboard on the laptop.
Since it does not work when click windows - account - lock screen, then I don't think this is keyboard issue.
All drivers up to date as well.
Only me in the company have the latest updates from Microsoft, the others get update using company policy. Problem started after June update.

Are you able to create a new user?
Can you run the dism commands to check the integrity of the operating system?
Can you perform an in place upgrade repair on the operating system?
Open administrative command prompt and type or copy and paste these commands:
Open administrative command prompt and type or copy and paste:
sfc /scannow
dism /online /cleanup-image /restorehealth
chkdsk /scan
4) net user test /add
5) When these have completed > right click on the top bar or title bar of the administrative command prompt box > left click on edit then select all > right click on the top bar again > left click on edit then copy > paste into the thread
msconfig (in the pop up system configuration > move the dot from normal startup to selective startup > uncheck load startup items > click service tab > in left lower corner check hide all Microsoft services > in the lower right side click disable all > click apply or ok > do not reboot)
taskmgr (in the pop up task manager > click on the start up tab > click on status so that the column sorts with enable rising to the top > right click on each row with enable and change to disable)

https://social.technet.microsoft.com/wiki/contents/articles/29876.how-to-perform-a-clean-boot-in-windows-10.aspx
8) shutdown /r (you will reboot the computer so that it is in clean boot)
9) log on with the new user named test
Evaluate the performance on your computer in clean boot during typical use.
How has the keyboard performance changed?
Some computer manufacturers have drivers for hot keys. Can you see if they are working? If not you would consider update the drivers for the hot keys. However what you are describing is more consistent with operating system problems or interference from other running programs.

company policy does not allow to disable Trend Micro Antivirus.
Can you kill any of its processes? I notice that some similar symptoms have been reported to be avoided by killing its tmproxy.exe for example. The idea would be, especially considering your "works for a while" symptom, that there is a queue somewhere that is not being flushed. Then killing the proxy (sounds like a queue) would be a method of restarting that.
Looks like there could be better choices than that one too
