Starting from this version, FlashBoot Pro can prepare Windows 10/11 installation USB thumbdrive (or install Windows 10/11 to USB thumbdrive in ToGo mode) with two types of privacy improvements (enabled independently of each other):

Politely ask Windows 10/11 to phone home less. These registry tweaks reduce Windows 10/11 background connections, though they don’t eliminate such connections entirely.
Inject privacy enhancing DNS proxy: a lightweight service that can block the following types of Windows 10/11 unwanted network activity, based on your preferences:

Windows builtins: Telemetry, Windows Update, MS Defender and SmartScreen, Cloud Logon & MDM Enrollment, Windows Push Notifications, Windows Store, Parental Control and MS Licensing.
Separate products: Cortana and Speech API, XBox, Zune and Groove, Cloud Graphics Apps, MS Edge, MS Wallet, Skype, OneDrive and MS Office 365.
Miscellaneous: Remote Access / Remote Help, MS Cloud Search, MS Maps and Location Services, MS News, Weather and Ads.
If you tick all checkboxes within this option, this will make Windows 10/11 stop phoning home completely. That is, you can make Windows 10/11 completely quiet on the Internet — if you want to.
