Microsoft today updated the Windows 10 beta, switching on a controversial technology that commandeers users’ upload bandwidth to shift some responsibility for updating from the company’s own servers.
Build 14915 was released earlier Wednesday to participants in the Windows Insider “Fast” track.
The notable change highlighted by Dona Sarkar, the software engineer who acts as the public face of Insider, was the enabling of Windows 10’s “Delivery Optimization” technology.
Delivery Optimization, formally dubbed “Windows Update Delivery Optimization” (WUDO) by Microsoft, was part of Windows 10 from the get-go. But it was only switched on as of the November 2015 upgrade, which was pegged as 1511. Insider builds of Windows 10, however, were exempt until now.
