if i remove Telemetry and xbox app will the Store and Start menu still work? ps.. what else can i remove?
You can Delete all Metro Apps and all Windows Componenten. Not,Not Delete the "Store-Metro" . And you habe the Store.
Easiest way is to click the Start icon, go thru the apps on the left and right-click & uninstall what you don’t want. If the system would suffer as a consequence, it won’t allow you to uninstall, so you’re safe.
