Thanks but I solved it with no fresh install. I did an in-place upgrade, I took ownership of the app folders, reinstalled all apps using 10Apps Manager, only mail and calendar were broken, I found I had 2 languages of it, I uninstalled Portuguese from Windows, I couldn’t erase the folders but I could rename, installed them again and voilĂ ! Fresh install was my next resource, fortunately I didn’t need it… I fixed just in time to use it at gym tomorrow.
