1) No -- but last night I uninstalled Start10.
2) English.
I am going to give the stock Win10 start menu a few days, to see if I can adapt to it. If not, I will reinstall Start10.
Btw, last night, after uninstalling Start10, I also tried Classic Shell, but uninstalled that after using it for a half hour or so. If I do decide to use a start menu modification program, it will definitely be Start10. Despite the small glitch I encountered. and despite the small license fee, it's far superior to anything else I found.
