This error indicates that Windows Update or one of its background services stopped unexpectedly during the installation process. In simple terms, Windows began installing KB5065789, but one of the critical services (like Windows Update, BITS, or Windows Modules Installer) shut down mid-process — interrupting the installation. 🔍 Common Causes 1. Windows Update Service Stopped During Installation The Windows Update (wuauserv) or Windows Modules Installer (TrustedInstaller) service may have crashed, stopped manually, or timed out while the update was running. This can happen if the update takes longer than expected or if Windows automatically restarts background services. 2. Corrupted Windows Update Components Damaged or incomplete files in the SoftwareDistribution or Catroot2 folders may cause the update process to fail when the system attempts to validate or apply the update. 3. System Resource or Power Interruption If the computer goes to sleep, reboots, or loses power while the update is installing, Windows may interpret this as the update service shutting down unexpectedly. 4. Third-Party Antivirus or System Optimizers Security software can stop or block background services for safety reasons, interfering with the update process. Some “system cleaner” or “optimizer” programs also disable background services temporarily. 5. Corrupted System Files or Component Store The WinSxS Component Store, which holds system update files, may be damaged. When Windows Update tries to access it, it fails, causing the installer to stop.
