Windows 10 Auto-Rotating Screen with domain accounts?!

I'm running a Windows Domain environment and have upgraded a majority of the users to Windows 10 Pro. All setup is done as a local administrator. When domain users log into their machine, it sometimes auto-rotates the screen to a Portrait view for no reason. I then need to flip the laptop sideways, use a wireless mouse and go into setting to set everything back to Landscape, but the screen rotation still happens at random. You can set "lock screen rotation" on or leave it off, making no difference to the situation, the rotation still happens regardless. This would be devastating during a customer presentation... and I need to do everything from happening again. We are also using HP Folio 9470m and 9480m laptops. It's odd that this seems to happen with domain users only thus far.... does anyone have any thoughts? I'll try to update the thread with the problem on video. Thanks!
