Need help on whether to clear TPM on not

Hi there! I'm here because I accidentally downloaded a malware and was suggested to reboot the laptop to get rid of it. I still do want to use the laptop afterwards and I've moved my documents and images onto a seperate device. The programmes i have installed, sadly no. So currently facing the same circumstances and so if the TPM is cleared, does this mean like the activation keys to softwares like MacAfee be cleared? Or like wifi passwords etc. Sorry I'm quite blur hahahahah.

It's clear as mud. As far as I can tell, it's specific to Windows, not necessarily activated programs like MacAfee, games, etc etc etc. MS Office, I have no idea.

Here's a lengthy doc on it: https://docs.microsoft.com/en-us/wi...initialize-and-configure-ownership-of-the-tpm

Clear all the keys from the TPM
With Windows 10, in most cases, we recommend that you avoid configuring the TPM through TPM.msc. The one exception is that you can use TPM.msc to clear the TPM, for example, as a troubleshooting step, or as a final preparation before a clean installation of a new operating system. Preparing for a clean installation in this way helps ensure that the new operating system can fully deploy any TPM-based functionality that it includes, for example, attestation. However, even if the TPM is not cleared before a new operating system is installed, most TPM functionality will probably work correctly.

Clearing the TPM resets it to an unowned state. After you clear the TPM, the Windows 10 operating system will automatically re-initialize it and take ownership again.

Clear TPM?

Hi,

I read online that it is recommended to clear the TPM in windows (not bios), before a clean install of Windows 11. Is this true? Or will windows 11 automatically clear the TPM under installation regardless?

Clear TPM?

Hi Thomas,

I'm Rodrigo and I will help you.

You don't need to clear TPM Keys before clean installing Windows 11, but you can do it if you want.

Installing Windows 11 does not clear the TPM keys.
