It can be attributed to the various processes running in the background, specifically “Windows modules installer worker”, as it tends to eat up a huge chunk of CPU and disk resources. Luckily, there are many ways to fix this error. We discuss a few of them below.
Tip: Check other Windows processes for high CPU and memory usage, including Microsoft Compatibility Telemetry, TiWorker.exe, and Wmpnetwk.exe.

What Is Windows Modules Installer Worker?
Windows Modules Installer Worker (also known as WMIW or TiWorker.exe) is an essential cog in the machinery of your operating system. Its job is to automatically check for any Windows and Microsoft updates and install them to make your PC run seamlessly at all times. Furthermore, it backs up your old data and ensures that everything is up to date on your PC.
Naturally, all these tasks require a lot of resources and processing power in the form of RAM and disk space. Therefore, sometimes you may see a decline in performance while WMIW is running in the background. You can also notice a spike in CPU usage every time you open the task manager in Windows, which is the reason why your PC heats up and slows down.
This is only a minor inconvenience you’ll have to face for an up-to-date operating system. Once the installation is complete, your PC should calm down and return to its normal state. However, if you notice that your CPU and disk usage have been high for a few hours, it may cause problems such as abrupt shutdowns, and you need to take action.
How to Fix Issues With Windows Modules Installer Worker
1. Restart the Windows Update Service
Sometimes the Windows modules installer can develop a glitch, causing the CPU to supply it with unnecessary high power. Often, this issue can be fixed by just quickly restarting the Windows Update service.

- Go to “Settings -> Network & Internet.” There, select the Wi-Fi option.
- Next, select the Wi-Fi network you’re currently on.
- Set your network as a “metered connection” using the toggle switch.
Case #3: You’re on an Ethernet Connection
- Press the Win + R keys to open the Run utility. In the command box, type
regedit
and hit Enter.
- Follow this path: “HKEY_LOCAL_MACHINE -> SOFTWARE -> Microsoft -> Windows NT -> CurrentVersion -> NetworkList -> DefaultMediaCost.”
- Right-click on “DefaultMediaCost” in the sidebar and click on Permissions in the context menu.
- Now, click on the Add button in the pop-up dialogue box.
- A new dialogue box will appear. Here, type your username in the empty field and click on “Check Names.” Then, press OK.
- You will be taken to the previous dialogue box, where your name will now be visible. Select it and look for “Full Control” in the permissions box below. Now, tick the empty box next to it under the Allow column.

4. Run an SFC Scan
By default, the purpose of System File Checker (SFC) is to scan Windows and restore your files if some Windows functions aren’t working or if Windows crashes. However, you can run this tool manually to resolve the issue with WMIW.

cmd
. Doing this will bring up the option to launch the command prompt. Launch it as administrator.
- In the command prompt, type
sfc /scannow
and hit Enter.
- Windows will now scan your PC so wait patiently for it to finish.
- Once the scan is complete, Windows notifies you if it spots any errors and also fixes them.
- If no errors are found, you’ll receive a message that says: “Windows Resource Protection did not find any integrity violations.”
- Restart your PC to finalize the changes.
