Windows 11 users are facing installation issues with the KB5068861 update from the November 2025 Patch Tuesday release, which addresses 63 critical security vulnerabilities. Errors reported include 0x80070306, 0x800f0983, and 0x800f081f. Affected users can wait for an optional release or use the Media Creation Tool, which downloads the same patch. Some users have reported a malfunctioning SMB search feature after the update. The installation errors have prompted reports of specific error codes, and attempts to resolve them through SFC scans or health checks have been largely ineffective. Downloading the .msu package from the Microsoft Update Catalog is recommended, followed by an installation attempt. If unsuccessful, the Media Creation Tool can be used while retaining user data. The November 2025 Update includes enhancements like a revamped Start menu, improved battery icons, and performance improvements, particularly for gamers. However, some users have encountered Bluetooth connectivity issues, especially on AMD PCs, with a temporary fix involving adjustments in Device Manager. The KB5068861 update has also caused a bug affecting search functionality over shared networks, leading to slower search results or empty listings for businesses. This issue arises from a breakdown in communication between the Windows client and the server’s search index. Users can restore functionality by restarting the Windows Search service or rebuilding the index. Additionally, the remote search functionality over SMB is compromised, preventing the Windows client from utilizing the server’s index. Users may need to uninstall the update to restore functionality, which requires disabling the Sandbox feature first. Specific DISM commands can be used to identify and remove the update, or it can be uninstalled through the Settings menu.
