Windows 11 version 24H2 was the biggest change to Windows 11 since it launched – a redesigned Start menu, new battery icons, and a wave of built-in AI features. It also had a rockier rollout than most feature updates, with a fair few compatibility issues reported in the months after release. If you held off deploying it fleet-wide, that caution was reasonable.

So what is 25H2, and do you need it?

Version 25H2 is built on the same underlying platform as 24H2. Rather than a full rebuild, it ships as an “enablement package” – a small update that switches on the next set of features, similar to how 22H2 to 23H2 worked. In practice that means the upgrade path is quick and low-risk if you’re already comfortably running 24H2: existing configurations, installed applications, and management policies carry across without a re-image.

If you’re still on an older version, the more useful question isn’t “24H2 or 25H2”, it’s “how much runway do I have left on what I’m on now”.

The dates that actually matter

• Windows 11 24H2 (Home & Pro) reaches end of servicing on 13 October 2026.
• Windows 11 24H2 (Enterprise & Education) is supported until 12 October 2027 – a full year longer, which is worth factoring into fleet planning if you manage a mixed licence estate.
• Older feature updates (23H2 and earlier) are already out of support for Home and Pro editions, with Enterprise/Education editions of 23H2 following in November 2026.

Our take

For most SME environments, staged deployment is still the right approach: pilot group first, monitor for a few weeks, then a wider roll-out once line-of-business applications and peripherals have been confirmed compatible. If you’re on a managed device fleet with us, this is exactly the kind of thing we track and phase in for you, rather than pushing a feature update to everyone at once and hoping for the best.
