Windows recovery operations disrupted by August 2025 updates
Microsoft released emergency out-of-band updates to fix a bug in the August 2025 Windows security updates that was causing recovery and reset operations to fail, as well as severe streaming issues with NDI software. The issue affected Windows 10 and older versions of Windows 11. The bug also caused Windows upgrades to fail with 0x8007007F errors on some Windows 11 and Windows Server systems. Additionally, the updates triggered unexpected UAC prompts and app installation issues for non-admin users. The affected updates included KB5063875, KB5063709, and KB5063877. The emergency fixes were released as KB5066189, KB5066188, KB5066187, KB5065426, and KB5065429. These updates are available via Windows Update and the Microsoft Update Catalog. Microsoft also resolved a bug that triggered Windows update failures when installed from a network share using the Windows Update Standalone Installer (WUSA). The September 2025 Windows security update reduces the scope for requiring UAC prompts for MSI repairs and enables IT admins to disable UAC prompts for specific apps by adding them to an allowlist.
