We already know that October 14, 2025, Microsoft will stop operating system support Windows 10, and the biggest concern of users of Windows, is as they will not be able to install Windows 11 if the PC does not have TPM support.
Before we see why TPM is a requirement of system / hardware requirements for Windows 11, let's explain briefly what this feature is and what it is used for.

What is TPM and what is it used for?
TPM is the acronym for Trusted Platform Module. A feature represented by a physical chip on the computer motherboard So, if you find that your PC doesn't have TPM, don't try to install software to help, because it won't work.
This physical chip (hardware) can be included directly in the motherboard (welded on the motherboard) or can be attached as an auxiliary component mounted on it. Especially in the case of computers that have been built on components.
Trusted Platform Module is a chip that deals exclusively with generation, storage si encryption key manipulation, digital certificates, tokens and electronic signatures.
Let's better understand, the data that is stored encrypted on our PC, even if they end up on another PC they cannot be opened / accessed. The TPM is a cryptoprocessor with unique features, and to further strengthen data security, this encryption chip can only communicate with the processor on the motherboard on which it was installed.
The first operating systems to use the TPM module were Windows 8.1 and Windows 10, for BitLocker. This data encryption tool on Windows can use the TPM module, but optional. AdministratorThe operating system can allow BitLocker to secure data in other ways, without TPM. But security was not at the same level.
In an older tutorial we showed how we can use BitLocker if we don't have Trusted Platform Module. How can we use BitLocker without a Trusted Platform Module (TPM).
TPM 1.2 vs. TPM 2.0 - Trusted Platform Module
Although they have a few elements in common, the two chips TPM 1.2 and TPM 2.0 are not compatible with each other. TPM 2.0 is an upgrade to TPM 1.2, but comes with a lot of improvements on the side encryption architecture and algorithms, offered more secure security options.
If TPM 1.2 uses a hash encryption algorithm SHA-1, which is very vulnerable, TPM 2.0 comes with an algorithm SHA-256 operating on 512-bit blocks. Also, TPM 1.2 does not support Device Encryption, Windows Defender System Guard, Autopilot si SecureBIO.
The first version of the module TPM 1.2 was initially launched in 2005, but it only started to appear on PCs on modelele since 2009. The final version of the TPM 1.2 cryptoprocessor was completed in 2011. The chip was initially used for banking systems, ATMs and other systems that required high security measures through encryption.
TPM 2.0 was originally released in 2014, but reached its final form in mid-2019. So we're talking about a relatively new encryption hardware technology, and those with older computers may have unpleasant surprises when they install. Windows 11.
Why is TPM "must have" on Windows 11
Even though we often say that the operating system Windows It has many security breaches and is a good environment for cyber attacks of all kinds, Microsoft has always tried to make strong security solutions available to users. This also happens with TPM 2.0. A data encryption module that can be used on Windows 11 to increase the security of sensitive information.
Microsoft initially announced that it would be able to install Windows 11 crypto processor TPM 1.2 or TPM 2.0 is required. In the hardware requirements documentation that appeared at some point, many users were a little scared, because only TPM 2.0 was specified. Microsoft is back on the TPM 2.0 craze, and as of this writing there are even some OEM systems that Windows 11 can be installed without TMP.
But it is certain that Windows 11 it can be installed without TPM if some tricks are used. I wrote about a trick in the article Fixed "This PC can't run Windows 11"And Install.
There is another problem. By introducing mandatory TPM 2.0 in hardware requirements, this means that Windows 11 it will no longer be able to be installed on any Mac with Intel. Apple no sign of wanting to come up with a update de firmware which allows TPM on modethem we of iMac with procesorare that have incorporated the module.
Most likely for users of Mac will come with arbitrary drivers via Boot Camp Assistant.
