Microsoft has acknowledged that the November Windows 11 security update can fail to install on some devices. Its KB5132061 release notes list repeated installation attempts and error codes 0x80070306, 0x800f0989 and 0x800f0993 among the symptoms.

Microsoft says an automatic repair is being delivered to affected devices connected to the internet and using Windows Update in Settings. No manual action is required to receive that repair. The announced rollout began November 11, with a 24-to-48-hour repair window; the security update should download and install automatically after the repair arrives.

If installation problems continue beyond that window, Microsoft directs users to Windows help or Microsoft Support. This is a newly documented installation problem, separate from the audio, printer and Remote Desktop fixes included in the update. See Microsoft's known-issue and repair guidance for current details.
