This bug has been present since 8.0 RTM.  I was hoping that 8.1 would have the issue resolved, but I have confirmed that the problem still exists.

- log in USER1

- move taskbar to secondary monitor

- log off USER1

- log in USER2

- move taskbar to secondary monitor

- log off USER2

- log in USER1.   [TASKBAR IS ON SECONDARY MONITOR AS EXPECTED]

- switch users; log in USER 2.  [TASKBAR IS ON SECONDARY MONITOR AS EXPECTED]

- switch users to USER1.  [TASKBAR IS ON PRIMARY MONITOR - bug]

- switch users to USER2.  [TASKBAR IS ON PRIMARY MONITOR - bug]

It seems to be switching from one active user to another active user that resets the taskbar location.  This is a fairly easily reproduced issue, and seems like a genuine problem. 

Hi,

I will forward this information to development department.

Thank you for reporting and your support.

Thanks kindly Tracy.

For further information, I believe the bug is related to the following registry key.  Here are the two different values before and after user switching:

HKCU\Software\Microsoft\Windows\CurrentVersion\Explorer\StuckRects2\Settings

Before:

28 00 00 00 FF FF FF FF 02 02 00 00 03 00 00 00 3E 00 00 00 28 00 00 00 80 F8 FF FF 10 04 00 00 00 00 00 00 38 04 00 00

After:

28 00 00 00 FF FF FF FF 02 02 00 00 03 00 00 00 3E 00 00 00 28 00 00 00 00 00 00 00 10 04 00 00 80 07 00 00 38 04 00 00

Warm regards,

Jordan.

Further, I've noticed that when the taskbar moves to the primary monitor after switching users, restarting the explorer.exe process restores it to its proper location.

Hi Tracy, could you advise if there is a way for me to track this issue in any way?

Kind regards.
