Microsoft Forces Windows 11 25H2 Update
Microsoft has begun forcibly installing the Windows 11 25H2 update on millions of consumer PCs running version 24H2, with no opt-out for unmanaged consumer devices. The push is described as preparation for the planned Windows 11 26H2 release in fall 2026. The 25H2 upgrade is small (around a 200 KB download) because it builds on the 24H2 codebase, installs in a few minutes, extends support by about a year, and focuses on security improvements including stricter runtime checks and AI-assisted code safety. Enterprise-managed devices are excluded from the forced rollout. The update also removes legacy components such as PowerShell 2.0 and WMIC.
A major platform vendor (Microsoft) is enforcing an OS-level update across millions of consumer devices, changing the baseline security and support posture for the Windows installed base and creating dependencies ahead of a future platform release (26H2). This affects device fleets, software compatibility and the broader ecosystem that runs on Windows.

Microsoft warns: Don't delay Windows updates beyond three days
Microsoft is urging Windows 11 users and IT administrators to install security updates quickly, recommending updates be applied within three days of release due to faster discovery and exploitation of vulnerabilities by AI tools. Jeremy Chapman, Director at Microsoft 365, warned administrators that delaying security updates increases risk as both defenders and attackers use AI to find and weaponize bugs. Microsoft previously allowed postponing Windows 11 updates for up to 35 days, but now recommends using Intune's Autopatch deadlines (one-day deadline recommended) and a maximum two-day grace period after installation before forcing a restart. Microsoft reported a rise in monthly security updates from 61 in February 2026 to 206 in June 2026.
