Download Windows 11 Version 25H2 ISO (Build 26200.7623)

Windows 11 Build 26200.7623 ships as part of KB5074109, the January 2026 Patch Tuesday cumulative update for Windows 11 version 25H2 (the same update lands as Build 26100.7623 for 24H2 devices 25H2 and 24H2 share a servicing branch, so the changelog is identical). It’s a mandatory security update, so it installs automatically unless updates are paused.

Whether you’re upgrading an existing Windows 11 installation or deploying new devices, Version 25H2 introduces meaningful improvements that enhance system responsiveness, application compatibility, and overall productivity.

What’s actually new in 26200.7623

Patch Tuesday updates are mostly fixes, not features, but this one carries a few concrete changes worth knowing before you deploy:

Fixes:

• A Windows Subsystem for Linux (WSL) bug that broke access to resources over VPN, first reported after the November 2025 security updates
• Azure Virtual Desktop (AVD) environments throwing errors on Remote Desktop connections
• NPU-related power consumption issue affecting battery life on some devices
• Security hardening for WinSqlite3.dll

Removed: Four legacy modem/serial drivers (agrsm64.sys, agrsm.sys, smserl64.sys, smserial.sys) — likely dropped for security reasons now that modern equivalents cover networking.

Security note for IT admins: starting with this update, eligible devices begin receiving new Secure Boot certificates as part of Microsoft’s broader certificate rollover — relevant given the original Secure Boot certificates start expiring in June 2026. If you manage fleets, check device eligibility rather than assuming blanket coverage.

Features still rolling out (you may or may not see these yet)

These aren’t guaranteed with 26200.7623 specifically — Microsoft is staging them gradually — but they’re active in this build cycle:

• Share with Copilot on the taskbar — hover an open app, share its screen directly with Copilot for in-context help. Toggle it off via Settings → System → Taskbar → Taskbar behaviour.
• Recommended feed in File Explorer — surfaces recently used/downloaded files; requires a Microsoft account, enabled via File Explorer → Options.
• Advanced Settings for virtual workspaces — Sandbox, Hyper-V, and similar features move from the old Control Panel dialog into Settings → System → Advanced Settings.
• Consistent dark mode in File Explorer dialogs — delete/move/error dialogs now respect dark theme.
• Full Screen Experience for gaming handhelds — Xbox app takes over the full screen, background processes get trimmed for more RAM/CPU headroom (handhelds only for now).
• Stutter fixes on high-refresh monitors and improved backlight response on HID-compliant keyboards.
