New Microsoft Emergency Windows 11 Update Fixes Boot Error After May 2025 Patch
Microsoft has released an emergency update for Windows 11 users after quite a few reported a big boot error following the May 2025 security update. The issue began with the KB5058405 update, which left some systems unable to start, displaying a 0xc0000098 error related to the file, as reported by Windows Report.
This problem was seen mostly on virtual machines, including those running on Azure and Citrix, but some other users on Windows 11 versions 22H2 and 23H2 were also affected.
To address the boot problem, Microsoft has now pushed out the KB5062170 update. This new patch is called a cumulative update, meaning it includes all previous fixes and patches along with the solution for the error.
However, users won't find it through Windows Update. Instead, Microsoft says it is only available for manual download from the Microsoft Update Catalog. The company says that those who installed KB5058405 without any issues do not need to install KB5062170.
An important point for users to note is that the KB5062170 update only addresses the boot error. There is a probable issue for those using Noto fonts in browsers like Edge or Chrome, where fonts may not render correctly if display scaling is set to 100%. Microsoft says increasing the scaling to 125% or 150% can help until a future fix is released.
Anyone whose PC is stuck in a boot loop with the 0xc0000098 message after the May update should download and install KB5062170 from the Microsoft Update Catalog. No restart is needed for those whose systems are running smoothly after the previous update.
