I recently updated my Windows Phone to Windows 10 Mobile. I want to erase all the older settings though like login accounts, app informations. So I finally figured out I'd have to hard reset my phone (Microsoft Lumia 640 XL). Although, I am confused that if I do hard reset it will I lose my Windows 10 update i.e., will it revert back to its original settings and OS(Win_8.1). Will it?
