What Is TPM In Windows? — Its Function And Importance Explained!

TPM provides security on a hardware level using cryptographic keys.


There are a lot of ways and modules that Windows uses to keep the user secure. One of the methods is by using TPM which stands for Trusted Platform Module. Here’s everything you need to know about TPM.

What Is TPM? What Does It Do?

TPM provides security-related functions on a hardware level. It’s basically a crypto-processor that helps you to generate, store, and limit the use of cryptographic keys. Didn’t get us? Here’s how it works in Windows.

During Windows’ boot process, a boot code is loaded. This includes the firmware and the OS system components necessary for the start-up. It helps with the integrity measurements (how the system started), and the generated keys are cross-checked to make sure that a TPM-based key was only used during the boot process.

If you still don’t understand what it is, all you need to remember is – it is there so that attackers can’t bypass the encryption and gain access to your files. It’s related to encryption. If you enable BitLocker disk encryption, Windows will store the encryption key inside the TPM chip. You access the encrypted drive by simply typing in your Windows login password, Windows gets the key from TPM, and you can re-access your files.

The new Windows 11 has TPM 2.0, and a lot of users are facing the TPM 2.0 error when installing Windows 11. If you’re one of them, here’s how to fix the TPM 2.0 error. If you want to know the differences between TPM 2.0 and TPM 1.2, check out this article from Dell. This should also give you a better idea of how TPM works and what algorithms it uses.

The new Windows 11 brings the ability to run Android apps natively, improves your Gaming experience, brings UI improvements, multi-monitor support, and many other features that we have discussed in this article.
