What is TiWorker.exe?

The genuine TiWorker.exe file is a software component of Microsoft Windows by Microsoft Corporation.
"Tiworker.exe" is by Microsoft. Its parent process is "TrustedInstaller.exe". Both reside in "C:\Windows\servicing" and are part of the Windows Module Installer Service. They apply Windows Update packages to the "C:\Windows\WinSxS" component store to update OS components rather than individual files. They also update the hard links into the component store found in "C:\Windows\System32" and other Windows OS directories so that Windows runs the updated component(s). Because the CPU usage of "Tiworker.exe" when it runs just after booting up is sometimes high, online advice to disable it is frequent. It should not be disabled, deleted, or uninstalled. That will prevent proper installation of Windows Update files, which may prevent crucial security updates. (The WannaCry ransomware exploited a bug fixed in an update two months before it appeared.) Microsoft Corporation introduced "side-by-side assembly" in Windows Vista to mitigate a developing DLL version conflict problem in Windows XP.
