How to fix TiWorker.exe high Disk Usage problems on Windows 10, 8.1, 8

TiWorker.exe (Windows Module Installer Worker) is a process that is related to Windows Update Service. Several times I have noticed that TiWorker.exe process is causing high usage issues on the Disk or on the CPU, on Windows 8.x and Windows 10 systems.

TiWorker is an essential process for the Windows Update service and starts at Windows startup every time you power up your computer. Normally TiWorker.exe runs on the background while your system checks for new updates and releases your system's resources, when the update is completed. But in several cases I have noticed that TiWorker.exe is hogging CPU or Disk resources and makes the system unusable.

The Windows Update Store folder (commonly known as "SoftwareDistribution" folder), is the location where Windows stores the downloaded updates.

1. Simultaneously press Windows key + R  to open run command box.

2. In run command box, type: services.msc and press Enter.

services.msc

 

3. Search for Windows Update service, then right click on it and select Stop.

4. Delete * (or rename e.g. to “SoftwareDistributionOLD”) the SoftwareDistribution folder.

* Note: Upon restart, the next time the Windows Update checks for available updates, a new empty SoftwareDistribution folder will be created automatically by Windows to store updates.
