TPM, short for “Trusted Platform Module”, is a standard type of hardware component included in many PCs to more securely store and process cryptographic data.
More information about the TPM standard is available from the Trusted Computing Group which maintains the TPM standard
This article is focussed on instances where TPM needs to be disabled for certain devices/users for features to work. Essentially to disable TPM/TCG [TCG is the name for some older models] you will have to enter the BIOS settings and look under the security tab. Below are a few examples.
The example here is from a Dell Latitude E5410
Under Security - > Deactivate/Disable TPM
The next example is an HP Probook 6550b
Here, simply uncheck the option "Embedded Security Device State"
For a few older models/desktops It may also be named as TCG like the picture below , here you have to enter the TCG setup and disable the settings. The device shown in the example below is a Lenovo ThinkCentre M78.
The above examples are shown as a guide to navigate your way through the TPM/TCG settings of your device in case you need to disable them to test certain settings.
