Besides the system patching, Windows Modules Installer Worker is responsible for system components installation or uninstallation.

The times when you can stop the Windows processes to increase the system performance have passed long ago.

    Frequently Asked Questions

    Can I just delete the process from the root directory?
    No. In case if the process belongs to the legitimate system element, you will not be able to edit the root directory of the system, where it is stored, without granting yourself permission for this action. And its deletion will surely lead to the loss of certain system functions, which may be needed in future.
    Is it possible to decrease the hardware consumption of this process?
    That process consumes literally nothing, so you will likely see no occasions when there is a need to make it less greedy with resources. However, if you see that it takes more than 20-30% of your CPU and the same amount of RAM, it is likely a virus. Perform the guide I wrote above.
    How can I know this process is malicious without checking its root directory?
    As was mentioned in the previous question, the CPU/RAM consumption of the original process is very low. So, the TiWorker.exe process that uses a lot of hardware capacity is definitely a virus. Another way to understand that this process belongs to a malicious program is its location inside of the Process Explorer.
