An unfinished build of supposedly Windows 11 has been leaked online and people are installing it. Based on the first impressions, it looks like Windows users are about to have a major overhaul: screenshots show an entirely new macOS-like desktop layout, a redesigned Windows Explorer interface, new start menus, and some of the best built-in Windows wallpapers ever had.
Some people are excited about the changes, others less, but it’s safe to say that everyone is at least curious about Microsoft’s technically not yet announced operating system (it is assumed that the upcoming Sun Valley Windows 10 update will be renamed Windows 11 ). However, you probably shouldn’t install the leaked Windows 11 update.
The reason is the same as with us Beware of installing beta builds from other operating systems and test apps like Chrome Canary: Windows 11 is unfinished and unstable. The leaked Windows 11 is also technically unofficial. So if you install it and something breaks, Microsoft isn’t going to help you fix it – and something is likely to break given how notoriously buggy official Windows updates are.
You also can’t install Windows 11 through official channels (you won’t find it on Windows Insider Channels), which means you’ll have to download it elsewhere – and hackers and phishers love to fool unsuspecting users with malicious links, which have been leaked as software.

I’m not going to deny that it’s fun to try new products early on, but there’s a reason Microsoft hasn’t announced Windows 11 yet, let alone released a beta version. Developers, journalists, and high-profile users can likely get away with trying Windows 11, but general users should stay away from it until Microsoft releases an official beta.
In all fairness, unless you have a secondary PC to test it out and keep your primary computer safe on Windows 10, for many of the reasons we mentioned, you should probably avoid official pre-releases as well.
Other Windows 10 users might feel the urge to try Windows 11 to “future-proof” their PC’s operating system – but fear not. Not only would the leaked Windows 11 be an incomplete experience compared to Windows 10, but Microsoft recently confirmed that it will support Windows 10 through October 14, 2025 – so even after Windows 11 officially launches, Windows 10 will be several more years received critical security updates for a long time.
Of course, that doesn’t take into account any forced update strategies Microsoft may be enforcing to get users to Windows 11 even if Windows 10 is still active, but in theory you can safely stick with Windows 10 for a while if you want. And for the foreseeable future, you should stick with Windows 10.
