ANDROID USERS:
It took about fifteen seconds after installing "Microsoft Launcher" to realize "NOPE". I went to default apps, in setting and found it, all the was available was Force Stop which when clicked did nothing,
Uninstall is there but greyed out. Right? this is your issue? You want the solution?
Well come to my site at ..... nah jk jk
What I found is that if you go to the top (I have galaxy note 8) and click the three dots you'll see "Uninstall for ALL users." Click that and its gone, all you're left with the **** Bing wallpaper.
Hope this helps, make sure to click that it helped you to others can find it.
Microsoft....I am a big supporter of yours, always have been. Thanks for all the good stuff you given us. But Launcher is NOT one of them. I also uninstalled as soon as I saw what Launcher was and how it radically transformed the UI and more on my phone. No No...you can't do changes like this without clearly providing an exit/undo path. Thanks to Cheeks 1944 . Just installed Launcher, Found uninstall answer and uninstalled.
