The leaked Windows 11 is also technically unofficial, so if you install it and something breaks, Microsoft won’t help you fix it—and something will probably break considering how notoriously buggy official Windows Updates are.

You also can’t install Windows 11 through official channels (you won’t find it on the Windows Insider Channels), meaning you’d have to download it elsewhere—and hackers and phishers love to dupe unsuspecting users with malicious links masquerading as leaked software.

Developers, journalists, and high-level users can probably get away with trying Windows 11, but general users should steer clear until Microsoft rolls out an official beta.
