Microsoft unveils Windows 11 25H2 – here’s who can try it now and how
Lance Whitney / Elyse Betters Picaro / ZDNETMicrosoft has rolled out the initial build of this year’s annual update for Windows 11, known as 25H2. Now available for Windows insiders, the 2025 version should install and run without too many hiccups, promising a smoother experience compared with the launch of the 24H2 edition.Also: Can’t upgrade your Windows 10 PC? Here are your options before it all ends in 3 monthsIn an IT blog post published Friday, Microsoft explained how and why Windows 11 25H2 is supposed to go down easy — certainly easier than its predecessor. First, the 25H2 installation package is smaller than for prior versions. With Windows 11 24H2, Microsoft performed an OS swap, completely replacing all the system files, even ones that didn’t need updating. That resulted in a larger package that took longer to install. With 25H2, Microsoft is replacing only the files that do need to be updated, so the installation will be leaner and run faster. Second, Microsoft is applying the same technology used in regular Windows updates to the 25H2 update. Through a process called “feature updates via servicing,” the new annual update is designed to install with just a single restart — one that aims to get you back to Windows quickly and easily.

The only difference is that any new features in the 2025 version are simply disabled in the 2024 version. This means that Windows insiders who want to test the new flavor only have to focus on the new features instead of all the apps, devices, and other OS components. Hopefully, Microsoft learned a few lessons from the debacle of Windows 11 24H2. Almost from the get-go, that edition was plagued by a series of bugs and glitches, one after the other. Updates that tried to fix one set of problems sometimes caused a whole new set. With all the issues and incompatibilities, the company was forced to block the update for a variety of PCs. Let’s keep our fingers crossed that 25H2 will be a much more stable and reliable version, even as Microsoft adds new features. More
