Using the Wireshark network protocol analyzer, the YouTubers were able to uncover some interesting, yet unsurprising, information about what kind of telemetry was being sent by Windows 11. At boot-up, even before an internet connection was made, they found that Windows 11 was already busy sending information to Microsoft and third-party servers. For example, the information went to software servers (possibly for updates, antivirus refresh, to check for trial versions, etc.) and to marketing/advertising networks.

In stark contrast, the 20-year-old Windows XP 64-bit version barely made a pip, if at all. The only telemetry that was sent was to Microsoft servers to check for OS updates.
