Downgrading from Win-10 1607 to Win-10 1511

Gabi · 16 Nov 2016

Recently Windows 10 on my desktop PC upgraded itself to Build 1607. Immediately my Brother printer stopped working (it was removed from the list of printers and could not be reinstated). Other funny things happened too. I downgraded back to Build 1511 and the printer now works, and the other problems were resolved too. However, the Mail and Calendar application stopped working. When the icon is pressed, nothing happens except one brief flash of the screen.
Anyone has an idea?

Firstly try uninstalling and reinstalling those apps then run the apps troubleshooter if they still don't work.

Before you faff around downgrading, I take it there isn't a driver on the Brother website. However I found that the list of printers in windows 10 can be updated, in the window where you pick the maker on the left and the printer on the right. There's a button labelled Windows Update I think. It takes time but it got the driver for a printer for me the other weekend.

I did remove the Mail app and reinstalled it, but nothing happened.
Where do I find the app troubleshooter? Is that specific to each app? Or a general tool?

The Stores App Troubleshooter is at Control Panel\All Control Panel Items\Troubleshooting\All Categories
