Microsoft has shifted away from bundling big feature drops into a single annual update. The newly released 25H2 is essentially a renumbered 24H2 with a few under-the-hood security tweaks.
According to Microsoft, 25H2 brings meaningful runtime vulnerability detection improvements. The release also removes legacy components: PowerShell 2.0 and the Windows Management Instrumentation Command-line (WMIC) are no longer included.
Why Microsoft treats 24H2 and 25H2 the same?
Both 24H2 and 25H2 share the same codebase and servicing branch. That makes life easier for Microsoft because it can ship identical patch packages for both versions next year.
For users, the main reason to move to 25H2 is support. Home and Pro editions receive 24 months of support, and support for 24H2 ends next fall. Moving to 25H2 extends that lifecycle by two years.
How to get the update?
The 25H2 update is being rolled out in waves and should appear in Windows Update soon. You can also install it manually using Microsoft’s update tools.
