Update KB5127936/26300.9818 Crashing System

Stuart Roberts 0

The latest windows update provided by Microsoft is causing technical issues with my computer system. On reboot, Microsoft Windows produces this error - D:WINDOWS\System32\Logfiles\SRT\srttrail.txt The exact description of this update is:

2026-10 Preview Update (KB5127936) (26300.9818). I have used system restore three times - did update, got errors every time. I have reinstalled Windows, keeping original files, did update, and then got errors on reboot. I have now delayed installation of this update in my system to November 10/2026.

How do I resolve this issue? My computer was working fine until this update came along.

Preview updates should be optional and are known to give problems some times.

I would suggest you ignore the preview and set Get updates as soon as they're available Off. See what happens when the normal update is supplied in the coming week.

Hi, good day!

Microsoft typically releases optional preview updates during the third or fourth week of each month. These updates allow users and IT administrators to test upcoming fixes and improvements before they are included in the following month's mandatory Patch Tuesday updates.

Since your computer is working fine while this update is paused, there's no need to install KB5127936 for now.

I also recommend reporting the issue through the Feedback Hub app so Microsoft can investigate it

https://support.microsoft.com/en-us/windows/apps/send-feedback-to-microsoft-with-the-feedback-hub-app

To reduce the likelihood of receiving optional preview updates automatically, go to Start > Settings > Windows Update and turn off Get the latest updates as soon as they're available. Then restart your computer.

Das Problem ist bei mir auch bekannt bei der Installation von: "2026-10 Vorschauupdate (KB5127936) (26300.9818)". Mein PC ist danach immer abgestürtzt und nach der deinstallation des Update läuft der PC wieder normal
