"Spyware systems, which are abundant in Windows 10 by default, have not been disabled using group policy, registry entries or various other workarounds – they have been entirely removed and deleted from the system, on an executable-level. This includes Windows Update, and any related services intended to re-patch the system via what is essentially a universal backdoor. Core applications, such as the included Edge web-browser, Windows Media Player, Cortana, as well as any appx applications, have also been successfully eliminated. The total size of removed files is about 2 GB."
