Before the launch of Windows 10, both my desktop and laptop were running 8.1. I got the Windows 10 invite on the desktop and upgraded the desktop to 10. The invite has not shown up on the laptop. I do use the same gmail account on both computers. Maybe it's irrelevant, but I have noticed that when I change the slideshow on the 8.1 laptop, my Windows 10 desktop plays the same slideshow as the laptop automatically. Same slideshow, but not the same photos at the same time. Do either of those things have anything to do with not getting the Windows 10 upgrade on the laptop. One more thing, the desktop is wired to the router, the laptop is wireless to the same router. Any comments or suggestions will be appreciated.
