Hi,

Thanks for trying to reproduce the problem.

I don't have a administrator privilege and I run taskmgr by another user having an administrator privilege .

In my case,

1. I logon to Win10.
2. I start some applications. All windows are shown.
3. I run cmd.exe.
4. I run "runas /user:administrator cmd.exe". This cmd.exe has an administrator privilege.
5. I run taskmgr on the second cmd.exe which is run by administrator.

Taskmanger window doesn't be shown.
Note that "always on top" property of taskmanger should not be set to reproduce the problem.

Thanks,

I am using Win10 64bit RS3 and don't have 8.1, so I'll test on RS4 within a week.

My previous e-mail had one mistake. I tested on RS3(build 1709). I cannot install RS4 by a company rule, but I suppose my test is effective on RS4.

Is this solved yet? For work, I rather often start DHCP, DNS & AD Users as a different user (right-click) to run them as a domain admin and then I won't see them. The window is there (as I see it in the taskbar) but no way can I show the actual window. Turning off Groupy and it works (even after turning on Groupy again).
