Windows 10, multiple monitors, Can't set Main display

[Eddie Castle]

I just upgraded from Windows 7 to Windows 10, having trouble with multiple monitors. My main monitor is a regular computer screen, the other is a television connected via HDMI. Whenever I press "Windows + P" and choose "extend," everything (icons, Open Windows) is transferred away from my computer monitor to the television screen. Before upgrading, it would stay on a my computer monitor. If I go to "settings", "system," "display" there is a box "make this my main display" that is grayed out. Any ideas on how I can get everything to stay on my computer monitor with I click extend?

Ummmm, if you have a problem and find a solution, please post. Don't just say, "Scratch that, got it to work", this doesn't help anyone.

Right click on the taskbar, open properties, and uncheck the checkbox that says "Show taskbar on all displays"
