Microsoft has released Patch Tuesday updates for Windows 11 25H2, 24H2, 23H2, and 22H2. The 25H2 and 24H2 update is provided via KB5072033, build 26100.7462 on 24H2, and build 26200.7462 on 25H2, after applying the updates.

The changelog is given below:

Highlights

• This update addresses security issues for your Windows operating system.

Improvements

[Copilot] Fixed: This update addresses an issue where Ask Copilot didn’t activate the Click to Do window as expected. The window now appears in the foreground when you share data with Copilot.

[File Explorer (known issue)] Fixed: This update addresses an issue where File Explorer briefly flashes white when you navigate between pages. This issue might occur after you install KB5070311.

[Networking] Fixed: This update fixes an issue where external virtual switches lose their physical network adapter (NIC) bindings after a host reboot. When this happens, the switches revert to internal mode, resulting in loss of network connectivity for virtual machines and blocking normal server operations.

[PowerShell 5.1] Invoke-WebRequest now includes a confirmation prompt with a security warning of script execution risk. You can choose to continue or cancel the request. For additional details, see CVE-2025-54100 and KB5074596: PowerShell 5.1: Preventing script execution from web content.

These updates will be available from Windows Update and should install automatically in most cases. If you would like to download these updates for offline installation, you can get them from the Microsoft Catalog website. You can find the update for 25H2/24H2 at this link.
