If there was any doubt about the legitimacy of the leaked build of Windows 11 circulating in dubious corners of the Internet, Microsoft seems to have dispelled it

As Fossbytes discovered, the company has filed a DMCA copyright complaint against Google, targeting the Indian site Beebom, which Microsoft claims distributes unreleased software The complaint is being indexed by the Lumen Project, which calls itself "an independent research project studying cease-and-desist letters regarding online content"

The complaint comes from Microsoft Japan and simply states, "The Beebomcom article distributes Windows 11 ISO (copyrighted by Microsoft) Please remove their articles from your search" If this isn't clear enough, the last line emphasizes the point: "This is a leaked copy of an unreleased Windows 11

The Windows 11 builds that have been circulating have traditionally consisted of cosmetic changes rather than the dramatic changes that would herald the launch of an entirely new operating system, and could be put away as either a hoax or legitimate but outdated However, this DMCA removal request from Microsoft seems to indicate that this is indeed the new operating system that Microsoft intends to debut on Wednesday

Of course, this is not the final version of Windows 11 The leaked build is clearly an early one, labeled 219961, and there were likely many more builds between that and what was available to consumers when Microsoft released it

There have been hints for some time that Microsoft is planning something big for Windows At the recent Build developer conference, CEO Satya Nadella said that Microsoft is preparing to "share one of the most significant Windows updates in the past decade," and in a tweet from Chief Product Office Panos Panay promoting Wednesday's event, light It appears to include a sneaky "11" under the shifting Windows logo

Importantly, Microsoft also updated its Windows 10 lifecycle policy page to set a Windows 10 retirement date of October 14, 2025 The company usually gives people a long window to upgrade, so one would imagine that Windows 11 will be released long before that deadline approaches
