Scope and symptoms of the issue
Microsoft has confirmed that the November 2026 security update fails to install on certain Windows 11 machines. Many users reported that the installation process freezes midway before throwing error codes 0x800f0989 or 0x800f0993.
According to a service message cited by BleepingComputer, affected systems may repeatedly attempt to reinstall the update. Devices might also display error codes 0x80070306, 0x800f0989, or 0x800f0993.
Microsoft stated that the issue impacts only a limited number of systems. Specifically, it only occurs on machines that have installed the October 2026 non-security preview update (KB5127936). Devices without this update remain unaffected.
Resolution and timeline
For IT administrators, Microsoft noted that the error will be resolved automatically across all affected devices, at the latest by Friday morning. End users do not need to take any action to receive the fix.
According to the company, devices will be resolved within 24 to 48 hours, starting from 10:00 AM (PT) on November 11, 2026. Once the fix is applied, the machine will automatically download and install the November security update via Windows Update. If the error persists after 48 hours, administrators are advised to contact Microsoft support.
Previous Windows update issues this year
This is not the first time Windows Update has run into trouble this year. Back in March, Microsoft had to pull a Windows 11 non-security preview update (KB5079391) due to installation error 0x80073712.
In May, the company resolved an issue where the May 2026 Windows 11 security update (KB5089549) failed to install with error 0x800f0922. Then in June, Microsoft warned that some devices upgrading to Windows 11 24H2 or 25H2 might encounter errors 0x80073712 or 0x800f0993 during monthly update installations.
For individual users, the safest approach right now is to wait for the automatic fix rather than manually tinkering with Windows Update. Organizations managing multiple machines should audit systems that have installed KB5127936 to identify at-risk endpoints. This string of recurring issues throughout the year demonstrates that monthly preview updates still carry risks, making it wise to test them on a small pilot group before broader rollout.
