The recovery feature is done by the OEM/Builder using the installed version of the OS, puts it back to the day it was shipped to the store or buyer, quite normal. It doesn't have to be used unless there's no other choice in repairing the computer. Win10 has a built-in System Reset that works pretty good. Usually the recovery is a partition on the only drive or it could be on a second physical drive and there's a procedure by the OEM/Builder for activating it. I've not tried it but some have had success in deleting the software needed by that process.
