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.

This seems to have worked for me. I found the process with System Explorer (I really like this little program; sits in your tray and gives you a nice visual about what the system is up to), set it to 'under normal' and restarted it. So far, so good. B Pratt

crucial system process for windows updates. Do not delete! UD
windows is performing an update.
it chews up lots of HDD resources
It's a key component of windows updates, although it does use a lot of CPU. Sadly you can't fix this and you just need to work through the 50% cpu usage which is VERY inconvenient but a necessary part of windows. computer guy
TiWorker.exe is an important process used along with dism.exe. It allows files t be installed in the update process. Removing TiWorker.exe will mean that you can't get updates. Malware can disguise themselves as TiWorker.exe in the C:\Windows\System32 folder. If you want to just to be safe, you can run a virus scan if you want too. Epic Gamer

Best practices for resolving TiWorker issues
A clean and tidy computer is the key requirement for avoiding problems with TiWorker. This means running a scan for malware, cleaning your hard drive using 1cleanmgr and 2sfc /scannow, 3uninstalling programs that you no longer need, checking for Autostart programs (using 4msconfig) and enabling Windows' 5Automatic Update. Always remember to perform periodic backups, or at least to set restore points.
Should you experience an actual problem, try to recall the last thing you did, or the last thing you installed before the problem appeared for the first time. Use the 6resmon command to identify the processes that are causing your problem. Even for serious problems, rather than reinstalling Windows, you are better off repairing of your installation or executing the 7DISM.exe /Online /Cleanup-image /Restorehealth command. This allows you to repair the operating system without losing data.
To get your computer running as fast as it did on day one, you can 8reset your PC. Your personal files will remain intact, but any programs you installed will need to be reinstalled.
To help you analyze the TiWorker.exe process on your computer, the following programs have proven to be helpful: ASecurity Task Manager displays all running Windows tasks, including embedded hidden processes, such as keyboard and browser monitoring or Autostart entries. A unique security risk rating indicates the likelihood of the process being potential spyware, malware or a Trojan. A good Bantivirus software detects and removes sleeping spyware, adware, Trojans, keyloggers, malware and trackers from your hard drive.
