2026-06 Update KB5095093 26200.8737 will not install

Hi Don Etheridge,

Experiencing a continuous restart loop with preview update KB5095093 typically indicates that the local installation payload or cryptographic catalog is corrupted. To resolve this, you must force the operating system to clear these broken files and download a fresh copy. Open your Start menu, search for Command Prompt, and select Run as administrator. You must halt the background update services by executing the commands net stop wuauserv, net stop cryptSvc, net stop bits, and net stop msiserver one after the other. Once the services are successfully stopped, you can safely back up and hide the corrupted files from the update engine by running ren C:\Windows\SoftwareDistribution SoftwareDistribution.old followed by ren C:\Windows\System32\catroot2 catroot2.old. Finally, restart the background services by executing net start wuauserv, net start cryptSvc, net start bits, and net start msiserver. Windows will automatically generate clean folders for a fresh download attempt.

If the restart loop persists, underlying system file corruption may be blocking the installation. In that same administrator Command Prompt, run sfc /scannow to thoroughly check and replace any damaged local system files. Afterward, execute DISM /Online /Cleanup-Image /RestoreHealth to allow the Deployment Image Servicing and Management tool to fetch healthy replacement files directly from Microsoft's secure servers.

Should these repairs fail to resolve the automatic update loop, bypassing the delivery mechanism is the most effective fallback. Open your web browser, navigate to the official Microsoft Update Catalog website, and search for KB5095093. Download the standalone offline installer package for your specific system architecture and run it locally. This bypasses the automatic Windows Update engine entirely and forces the installation using a complete, uncorrupted file package.
