I don't know the law of how to reproducte it. it was accidentally.
The mouse clicking did not get any response. But when I Ctrl+alt+del to get the winlogon desktop and leave to normal desktop, the mouse clicking was fine.
Here is two video and systeminfo(https://pan.ruijie.com.cn/share/f48777d7a2673ecc2d6aafb140). taskbar.mp4 told me that mouse clicking at taskbar and the win button didnot get any responce. DestopButMycomputer.mp4 told me that desktop shotcut was fine, alt+f4 of edge was fine, but mouse clicking at my computer, edge was bad.
I thought that csrss.exe get the mouse event from hardware, and dispatched to other window, csrss deal the event of ctrl+alt+del and create the winlogon desktop. Could it be something wrong with csrss?
Could you help me how to fix this problem?
