Microsoft rolls emergency fix for Windows 11 May update install failure tied to EFI space

Microsoft says the May 2026 Windows 11 update KB5089549 can fail to install when the EFI System Partition runs low on space, triggering errors such as 0x800f0922. An emergency server-side patch is rolling out, and Known Issue Rollback mitigates the issue; a few reboots may help apply the fix. The ESP is typically around 100MB, but firmware bloat or multiple OS installs can exhaust it, possibly causing install loops. Some users also report missing taskbar animations and extra reboots due to Secure Boot updates.
