Software solution

Are you looking for a software that can block telemetry, Windows Updates, OneDrive, builtin ads, tracking of your location and other unwanted Windows network activity on your PC?

Are you tired of mere “registry tweakers” whose tweaks are mostly ignored by Microsoft anyway, and after applying all of them, 95% of Windows traffic still gets through to the Microsoft?

Do you need truly airtight remedy for data leaks?

FlashBoot and Emergency Boot Kit are the ultimate solutions you’ve been looking for.

• Use FlashBoot to create a USB installer for privacy-enabled Windows OS.
• Use Emergency Boot Kit to add traffic filtering to your existing Windows installation — no reinstall needed.

They can block all unwanted traffic of Windows 10/11, making the OS completely quiet online — something other tools can’t achieve.
