What is TiWorker.exe?

The TiWorker.exe is an .exe file that is linked with the Windows’ Consumer Preview ISO developed by Microsoft. The latest version of TiWorker.exe so far detected is 1.0.0.0 and it contains a security warning of UNKNOWN.

This file is responsible for installing updates and new modules but produces a great load on the disk, triggering CPU usage to as much as 70% and in some extreme cases 100%. As a result, you will face a poor system performance and it’s pretty frustrating. It must be noted that it is an essential process but at times when it consumes too much of CPU usage, you should try one of the following solutions.

2: Have Patience

If you’ve faced this issue for the first time, we recommend to wait and allow the file to complete its work.

You can speed up the process by closing your applications and leave the PC idle for a few moments. Normally, after 30 minutes to an hour, TiWorker.exe would have completes all of processes and your CPU performance will be back to normal.

3: Updates

Many times, it happens that outdates software or pending updates might result in this issue. You can perform a manual check for updates.

If you see any pending updates, install them and reboot your system. This prevents TiWorker.exe to use CPU very often.

4: Reboot

In case step 2 doesn’t work, simply reboot your system. It usually solves the problem. After rebooting, check if the file is still consuming too much of CPU process from the task manager.

5: Run the System File Checker

Finally, triggering a check on your system files can also help to detect the problem and resolve it.

To do this, right click on the Windows icon in the lower left corner of the screen and tap on Command Prompt (Admin).

Now type sfc/scannow command and hit the enter button.

This can take anywhere from 30 minutes and as much as 1 hour to complete.

Once the System file checker has successfully scanned for all the files, you’ll receive one of the two messages.

  • Windows Resource Protection did not find any integrity violations.
  • Windows Resource Protection Found Corrupt Files.

In case of first message, no further action is required. However, if you receive the second message, then you need to type in the below command to fix the corrupt files.

“Dism/Online/Cleanup-Image/RestoreHealth”

Press the enter button to start the cleanup. Once it’s done, you will be notified. Reboot the PC and check again for the CPU usage.

Tip: You can download Ccleaner, it is a free software utility. It helps to clean any unnecessary files on your computer and junk off the malware. Run it once a week to keep your system performance up.
