Windows 10: Windows wrongly moved to primary monitor when switching on secondary monitor, and...

First issue: When I switch my secondary monitor off, nothing changes good.However, when switching back on, all windows are moved to the primary monitor!!!That's stupid. I would accept if that happend when switching off, but not when switching back on!!!Secondary issue: The window moves to the primary monitor WM_MOVE, but no WM_SIZING or WM_SIZE, and is followed by a WM_DPICHANGED message, which has the proper DPI values, but the window size is not changed accordingly!2 = primary windows/desktop monitor1 = extend desktop to this monitorTest-App which currently is fixed-size, but still supp

The taskbar locked to bottom of secondary monitor moves to the primary monitor whenever primary monitor is switched on.

See the title.

I have the taskbar locked at the bottom of the secondary monitor so the primary monitor is completely empty for watching movies, games TV etc.

Whenever I turn the primary monitor on, the taskbar immediately jumps from the bottom of the seconday monitor over to the bottom of the primary monitor. I then need to untick the 'Locked' option on the taskbar, drag it back to the secondary and tick 'Locked'
again.

The taskbar disrupts desktop icons on the primary and any application running on the primary monitor at the time and quite frustrating.

Primary monitor is an Asus PB328, connected via Display Port to the PC.

Secondary monitor is a Samsung 24 connected via DVI to the PC.

I expect the taskbar to remain where I place it when locked, regardless of monitors been switched on or off.

The sequence of turning on the primary and secondary monitors has no impact. As soon as the primary monitor (Asus on DP) is turned on, the locked taskbar moves to the primary display, regardless of whether the Samsung is on or not.

 

Windows & desktop icons on secondary monitor are moved to primary monitor after standby

I had been using 2 monitors with the same resolution (1280x1024) without issues. I recently replaced my primary monitor with a 1920x1080 monitor. Every time the system wakes up from standby everything from the secondary monitor is moved to the primary monitor.
Strangely enough, the desktop icons and the windows (explorer & applications) are not always moved.

I have already tried to delete corrupted registry entries as stated in
this thread. There were 3 monitors listed with different resolutions. That did nothing.

System specs:

OS: Windows 7 pro (64-bit)

Video card: AMD R7 260X

primary monitor cable: DVI

secondary monitor cable: DVI output -> VGA adaptor

 

I want to move spell checker window to a non primary monitor

I use my Internet Explorer on my secondary window. I have a misspelled word, I right click, the window with suggestions add to dictionary, is on the primary window. I don't want that. If I change primary and secondary windows, I can't move my mouse left
to right, its stops at the new secondary window.

I want to move the suggested spelling window to the secondary monitor.
