1,Open Computer Management,Open Event Viewer,view Event content: Figure: Point Close Button; 2,Close Computer Management,display Prompt: Figure: Only kill mmc.exe Process.
If it's anything like what I get in W7, try to minimize the window or move it, you should see an open event pop-up window hidden behind the compmgmt.msc window. Once you close that window, you can close the mgmt window.
I cannot replicated it, but in task manager -> end process -> Microsoft Management Console (mmc.exe) should close it. I have heard of one maybe two other people who open events to view and then cannot close mmc, I cannot offer more since it isn't happening at this end, sorry.
Has been resolved, Install Chinese input method, after opening, then turn on MMC.EXE and view event ,the above error
