General Purpose

This security update contains fixes and quality improvements from KB5070311 (released December 1, 2025). The following summary outlines key issues addressed by this update:[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.[System Components] The AppX Deployment Service (Appxsvc) has moved to Automatic startup type to improve reliability in some isolated scenarios.

General Sentiment

The general sentiment towards this update is mixed. While it addresses several important issues, including fixes for Copilot, File Explorer, and networking problems, there are also known issues that users have reported. The File Explorer flashing issue and the networking problems with virtual switches seem to be well-received fixes. However, the PowerShell 5.1 change to include a security prompt for Invoke-WebRequest may be seen as an inconvenience by some users.Additionally, there are reports of the update causing system freezes and crashes on some devices, especially those with older hardware that may not fully meet the Windows 11 requirements. This has led to frustration among users who are unable to successfully install the update.Overall, the update appears to provide meaningful improvements, but the known issues and compatibility problems are causing concern among the Windows 11 community. Careful testing and monitoring is advised before broadly deploying this update, especially in enterprise environments.
