Microsoft has resolved a known issue that caused Windows upgrades to fail with 0x8007007F errors on some Windows 11 and Windows Server systems.
Although this issue impacts both Windows client and server platforms under specific upgrade paths, it will not affect customers attempting to upgrade their devices to Windows 11 24H2 and Windows Server 2025, the latest Windows versions.
"Starting August 12, 2025, some Windows upgrades might fail with error code '0x8007007F' when performed via 'Windows Setup > Upgrade' installation," the company noted in a new entry on the Windows release health dashboard.
The list of upgrade paths impacted by this bug includes:
- Upgrades from Windows 10 1809, Windows 10 21H2, and Windows 10 22H2 to Windows 11, versions 23H2 and 22H2
- Upgrades from Windows Server 2016 to Windows Server 2019 or Windows Server 2022
- Upgrades from Windows Server 2019 to Windows Server 2022
While the company didn't share what was causing these upgrade problems, Redmond says the bug triggering them is now fixed.
Users who experienced issues while trying to upgrade their systems are now advised to retry the upgrade process.
"This issue was resolved as of August 15, 2025. Devices upgraded after this date should no longer encounter this error. If you do experience error '0x8007007F', retrying the upgrade process will typically resolve the issue," Redmond added.
This week, Microsoft has also released emergency out-of-band updates to address a bug that caused Windows reset and recovery to fail after installing the August 2025 security updates.
Additionally, Microsoft rolled out a Known Issue Rollback (KIR) fix last week for a bug that triggers Windows update failures when installed from a network share using the Windows Update Standalone Installer (WUSA).
The company also resolved a separate issue triggered by the installation of the KB5063878 update, which caused the August 2025 security updates to fail with 0x80240069 errors on Windows 11 24H2 systems when delivered via Windows Server Update Services (WSUS).
