How to Fix the Trusted Module Platform (TPM) Error in Windows 10

A Trusted Platform Module (TPM) is a hardware-based security measure used to authenticate your PC. Sometimes, the TPM may malfunction, resulting in users not being able to access applications such as Outlook or Microsoft Office. Thankfully, there are quite a few ways you can fix the TPM malfunctioning error.

Perform a Clean Boot

The first step in resolving common Windows errors is to perform a clean boot to check whether third-party software is causing the issue. It’s not unusual for third-party software to conflict with your Windows PC. Here’s how you can clean boot your PC:

1. In the Start menu search bar, type sysconfig. In the search results, click on System Configuration.
2. In the next window, click on the Services tab.
3. Check the Hide all Microsoft services box.
4. Then select all the services listed in the window, and click Disable all.
5. Click OK and close System Configuration.
6. Now, press CTRL + Shift + Esc to launch the Task Manager.
7. Under the Startup tab, click on each service one by one and click on Disable.
8. Click on OK and close Task Manager.
9. Reboot your computer.

If the error doesn’t appear, then uninstall any recently installed third-party application. Then reverse the changes you made and use your computer as you would. Alternatively, take a look at how to perform a clean boot in Windows 10 to understand better how the process works.
