What is tiworker.exe?

Tiworker.exe is a legitimate Windows process that is responsible for performing system maintenance tasks such as Windows update installations, system file verification, and disk optimization. The process is usually located in the C:\Windows\System32 folder.

While tiworker.exe is a legitimate process, it can sometimes consume a significant amount of system resources, causing high CPU or disk usage. This is often seen during Windows update installations or system maintenance tasks.

If you notice that tiworker.exe is consuming an excessive amount of system resources for a prolonged period, it could be a sign of an issue such as a stuck update or corruption in the Windows update components. In such cases, restarting the Windows Update service or running the Windows Update Troubleshooter can help resolve the issue.

It is important to note that tiworker.exe is not a virus or malware, but it is always recommended to have a trusted antivirus program installed on your system to prevent any malicious software from disguising itself as legitimate system processes.
