Microsoft confirms patching issues in restricted Windows networks
BleepingComputer • • technology
Key Points:
- Microsoft warns that customers in restricted network environments may face Windows Update failures after installing the January 2026 optional non-security preview updates, with error code 0x80010002 appearing during update attempts.
- The issue affects systems in isolated or heavily firewalled networks, preventing downloads of updates from March 2026 onward, though the February security update may still be installed successfully.
- The problem stems from recent changes in download timeout requirements and impacts the ability to download updates via Windows Update settings, not the device’s integrity or installation capability.
- Microsoft recommends IT administrators use Known Issue Rollback (KIR) group policies specific to their Windows version (e.g., Windows 11 26H1 KB5083806) to work around the problem, requiring policy installation and device restart.
- This update challenge follows previous Windows update issues in 2025, including bugs affecting enterprise update installations via WSUS, which Microsoft addressed through patches and fixes.
