Microsoft says some Windows 11 PCs can’t install November updates

Nov 12, 2026 · Summarized by Fundy Tech from BleepingComputer

The 30-second version

Microsoft confirmed that November 2026 security updates may fail to install on some Windows 11 devices that already have the October preview update. Affected PCs should repair themselves within 24 to 48 hours.

Key points

  • Issue affects some devices with KB5127936 installed.
  • Users may see 0x80070306, 0x800f0989, or 0x800f0993 errors.
  • Microsoft says the fix will arrive automatically by Friday morning.

Why it matters

If your office PCs are stuck on update failures, you may temporarily miss security fixes. Microsoft says no action is needed for the automatic repair, but IT admins should keep an eye on affected systems. For households, this mainly means waiting for the repair rather than repeatedly retrying the update.

Who’s affected: Some Windows 11 devices with the October preview update
