Today's Windows build 10586 didn't have the "watermark", so I took it as a "jumping off point" to exit the Insider program on the desktop, mainly due to the hassle the laptop gave me recently when it wouldn't update to the next Insider build.

Looks like the update to Windows​ insider Build 10576 is going to be a NO GO on the laptop. No matter what I do, get error 0x80070005. First time having this issue with the builds since starting them in January. The update on the desktop went flawlessly however.
