If you hear your computer’s fans spin up and feel it getting hotter for no apparent reason, check the Task Manager and you might see “Windows Modules Installer Worker” using a lot of CPU and disk resources. This process, also known as TiWorker.exe, is a part of the Windows operating system.
RELATED:What Is This Process and Why Is It Running on My PC?
This article is part of our ongoing series explaining various processes found in Task Manager, like Runtime Broker, svchost.exe, dwm.exe, ctfmon.exe, rundll32.exe, Adobe_Updater.exe, and many others. Don’t know what those services are? Better start reading!
What Is Windows Modules Installer Worker?
This system process “enables installation, modification, and removal of Windows updates and optional components”, according to its service description.
RELATED:What Windows 10’s “Optional Features” Do, and How to Turn Them On or Off
Windows 10 automatically installs operating system updates via Windows Update, so this process is likely just installing updates in the background. However, if you choose to uninstall an update or add or remove an optional Windows feature, the Windows Modules Installer Worker process will also need to do some work.
While the process is named Windows Modules Installer Worker on the normal Processes tab in Windows 10’s Task Manager, its file name is TiWorker.exe, and you’ll see that displayed on the Details tab.
Microsoft releases updates on “Patch Tuesday”, the second Tuesday of every month. They may also release updates on other days, if necessary. If this process is using a lot of CPU, it’s likely that your computer has just downloaded new updates from Microsoft.
You may or may not have to restart your computer to install these updates, but Windows does a lot of updating work in the background so you can continue using your PC while it installs the updates.
Why Is It Using So Much CPU?
Here’s the bad news: As far as we can tell, occasional high CPU usage from the Windows Modules Installer Worker process on Windows 10 is just normal.
The good news is that, if you allow it to run, the process will eventually finish and stop using CPU and disk resources. The Windows Modules Installer worker process will finish and it will disappear from the running processes in Task Manager. How long it will take depends on the speed of your computer’s CPU and storage, as well as on how many updates it needed to install.
Can I Disable It?
You’ll see some bad advice online recommending you should disable the Windows Modules Installer system service to prevent this from happening. This will prevent Windows from installing updates properly, and you shouldn’t do it.
RELATED:How, When, and Why to Set a Connection as Metered on Windows 10
Similarly, others may recommend setting your network connection to “metered”, which will prevent Windows 10 from automatically downloading and install many updates. This will prevent the Windows Modules Installer process from activating, but your computer won’t install critical security updates that can protect you from malware like the WannaCry ransomware, which exploited a bug patched two months before it was released. Avoiding operating system updates is dangerous, and we don’t recommend it.
Sure, you could install updates manually—but the Windows Modules Installer Worker process will run after a manual update, anyway. It’s probably best to just bite the bullet and allow the TiWorker.exe process to occasionally do its thing. This is just how Windows installs updates, and it’s for your own good.
Is It a Virus?
RELATED:What’s the Best Antivirus for Windows 10? (Is Windows Defender Good Enough?)
This process is a part of Windows itself. We haven’t seen any reports of malware disguising itself as the Windows Modules Installer Worker, or TiWorker.exe process. However, if you’re concerned about malware, it’s always a good idea to run a scan with your preferred antivirus program to check if anything’s amiss.
If You Think Something’s Wrong
If you think something’s really wrong—perhaps the Windows Modules Installer Worker process has been churning away for hours, or perhaps you think it just runs too frequently—there are some troubleshooting steps you can take. These won’t help if the process is just running for normal reasons, but can potentially fix problems with Windows Update and the Windows operating system itself that could cause issues with the Windows Modules Installer Worker service.
RELATED:How to Make Windows Troubleshoot Your PC’s Problems for You
The Windows Update troubleshooter can find and fix problems with Windows Update that could cause issues to occur. To run it on Windows 10, head to Settings > Update & security > Troubleshoot > Windows Update > Run the troubleshooter. Apply any fixes the troubleshooter suggests.
If the troubleshooter doesn’t help, you may want to try using the SFC or DISM tools to scan your computer for corrupted or missing system files.

64-bit versions of Windows 10 and 8 include a “driver signature enforcement” feature. They’ll only load drivers that have been signed by Microsoft. To install less-than-official drivers, old unsigned drivers, or drivers you’re developing yourself, you’ll need to disable driver signature enforcement.
With Windows 10’s Anniversary Update, Microsoft tightened the screws even further. But you can avoid the more restrictive driver-signing requirements by disabling Secure Boot.
Driver Signature Enforcement Is a Security Feature
RELATED:What’s New in Windows 10’s Anniversary Update
Before you begin, keep in mind: Microsoft isn’t just trying to make your life harder here. Driver signing enforcement ensures that only drivers that have been sent to Microsoft for signing will load into the Windows kernel. This prevents malware from burrowing its way into the Windows kernel.
How To Turn Off Windows Installer Logging
Disable driver signing and you’ll be able to install drivers that weren’t officially signed. Be sure you know what you’re doing! You should only install drivers you trust.
Option One: Enable Test Signing Mode
Windows includes a “Test Mode” or “Test Signing” Mode feature. Enable this mode and driver signature enforcement will be disabled until you choose to leave Test Mode. You’ll see a “Test Mode” watermark appear at the bottom right corner of your desktop near your clock, informing you that Test Mode is enabled.
You’ll need to run a command from an Administrator Command Prompt to do this. To launch one, right-click the Start button or press Windows+X and select “Command Prompt (Admin)”.
Paste the following command into the Command Prompt window and press Enter:
RELATED:How Secure Boot Works on Windows 8 and 10, and What It Means for Linux
If you see a message saying the value is “protected by Secure Boot policy”, that means Secure Boot is enabled in your computer’s UEFI firmware. You’ll need to disable Secure Boot in your computer’s UEFI firmware (also known as its BIOS) to enable test signing mode.
Restart your computer to enter test mode. You’ll see the “Test Mode” watermark appear at the bottom right corner of your desktop and you’ll be free to install whatever unsigned drivers you want.
To leave test mode, open a Command Prompt window as Administrator once again and run the following command:
Option Two: Use an Advanced Boot Option
RELATED:Three Ways to Access the Windows 8 or 10 Boot Options Menu
There’s also another way to do this. You can use the advanced boot options menu to boot Windows 10 with driver signature enforcement disabled. This isn’t a permanent configuration change. The next time you restart Windows, it will boot with driver signature enforcement enabled—unless you go through this menu again.
To do this, get to the Windows 8 or 10 advanced boot options menu. For example, you can hold down the Shift key while you click the “Restart” option in Windows. Your computer will restart into the menu.
Select the “Troubleshoot” tile on the Choose an option screen that appears.
Select “Advanced options”.
Click the “Startup Settings” tile.
Click the “Restart” button to restart your PC into the Startup Settings screen.
Type “7” or “F7” at the Startup Settings screen to activate the “Disable driver signature enforcement” option.
Your PC will boot with driver signature enforcement disabled and you’ll be able to install unsigned drivers. However, the next time you restart your computer, driver signature enforcement will be disabled—unless you go through this menu again. You’re now free to install drivers that haven’t been officially signed by Microsoft.

Method 1 – Set network type to Metered connection
Method 2 – Use Group Policy to stop automatically downloading updates
Method 3 – Completely disable Windows update in Windows 10
Method 1 of 3
Change your network type to Metered
By default, Windows 10 doesn’t download updates when you’re on a metered connection. In fact, Windows 10 will not download updates as long as you are on a Metered connection. You can make use of this by setting Metered connection property to your network connection.
The only catch is that you can’t assign Metered connection property to LAN networks, meaning WiFi and other hotspots can be set as Metered connection. Go through our how to set metered connection in Windows 10 guide for step-by-step instructions.
Method 2 of 3
Use Registry to disable Windows Update
In this method, we are going to use the Local Group Policy Editor. Since Group Policy Editor is not present in Windows 10 Home edition, this method is not applicable to Windows 10 Home.
Step 1: Open Local Group Policy Editor. To do so, type Edit Group Policy in Start or taskbar search box and then press Enter key. Alternatively, open Run command box, type Gpedit.msc, and then press Enter key to open the same.
Step 2: Navigate to the following policy:

Step 3: On the right-side, double-click on the policy labelled Configure Automatic Updates to open its properties.
Step 4: Select Enabled option. Under Configure automatic updating, select second option labelled Notify for download and notify for install. Don’t touch rest of the settings.
Click Apply button. As mentioned before, this method will not turn off Windows Update but you will be notified when updates are available to download. You can simply ignore the alert to avoid downloading and installing updates.
When this policy is enabled, you’ll see Some settings are managed by your organization message under Advanced options of Windows Update.
Method 3 of 3
Disable Windows Update permanently
This is the best method to completely disable Windows Update in Windows 10. In this method, we will disable the service responsible for checking, downloading and installing updates for Windows and other programs including Windows Defender.
Step 1: Type Services in Start menu or taskbar search box and then press Enter key. Alternatively, you can type Services.msc in Run command box and then press Enter key to open Services.
Step 2: Here, look for the service named Windows Updates. Right-click on it and click Properties to open Windows Update Properties dialog.
Step 3: Here, change the Startup type to Disabled. Click Apply button and then reboot your computer. That’s it!
From here on, Windows 10 will not be able to check for updates. Good luck!
