New Windows 11 25H2 December 2025 Update – New Features in the Main Release (Build 26200.7462 or KB5072033)

In this article, we will talk about the latest Windows 11 Update for the 25H2 Main Release, which is the Build 26200.7462 or KB5072033.

For those of you who are not familiar with how Windows 11 Updates for the Main Release work, I will explain it to you in the following lines.

Every month Windows 11 has a B and a C Release for Windows 11. Usually, the B Release is launched on the second Tuesday of the month and contains all the features that were tested in the previous month’s C Release.

New Improvements in this Update

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