Just wanted to update that I tried all this and it still doesn't work. First of all there was no 'CloudContent' under HKEY_LOCAL_MACHINE. I created one with the disable features key anyway. I did find a 'CloudContent' under HKEY_CURRENT_USER' and added a disable features key to that as well. I still get tipsss when I close my laptop lid OR hit windows key + L.
Also yes, background is a picture and not Microsoft Spotlight.
