What happened

According to The420.in, Microsoft has confirmed that some Windows 11 devices cannot complete installation of the November 2026 security update. The420.in reports that the update stalls midway and shows error codes 0x800f0989, 0x800f0993 or 0x80070306. It says affected systems may also retry the installation repeatedly without success. The outlet says the problem has mainly been reported with update KB5132061.

The420.in says Microsoft, in its service update notice, links the cause to the October 2026 non-security preview update KB5127936. According to the outlet, devices that installed that preview are affected, and devices without it are not expected to see the problem. The420.in quotes Microsoft as saying the issue affects a limited number of devices.

The420.in reports that Microsoft has started an automated repair. It says the repair began at 10:00 AM Pacific Time on November 11, 2026, and should resolve the issue within 24 to 48 hours. Per the outlet, affected computers will then re-download and install the November update without user action.

Not confirmed: the exact number of affected devices, which Windows 11 versions are involved, and any technical detail of the cause beyond the link to KB5127936. The Microsoft notice itself was not among the sources, so everything here relies on The420.in’s account of it. The source says nothing about exploitation of any vulnerability in connection with this issue.

Am I affected?

According to The420.in, you may be affected if both of these are true:

  • The device installed the October 2026 non-security preview update KB5127936.
  • The November 2026 security update (reported as KB5132061) stalls, loops, or shows 0x800f0989, 0x800f0993 or 0x80070306.

The420.in says devices without KB5127936 are not expected to hit this issue. Until the repair completes, an affected device may not have the November 2026 security fixes, which the outlet describes as important.

What to do now

  1. Check whether the failing devices have KB5127936 installed and whether they show the error codes listed above.
  2. Let the automated repair run. The420.in reports it should fix affected devices within 24 to 48 hours of its start on November 11, 2026, with no user action needed.
  3. Do not download manual fixes, edit registry entries or modify Windows system files. The420.in says Microsoft advises against all three.
  4. Avoid repeated manual changes to update settings, as the outlet advises.
  5. If installation still fails on your network after the 48-hour window, IT administrators should contact Microsoft Support, per The420.in’s report of Microsoft’s guidance.
  6. Once the repair finishes, confirm the November 2026 security update installed through Windows Update.
