Trusted Platform Module (TPM) 2.0, which is not supported by some older computers, is imperative for Windows 11, Microsoft says.
As the end of Windows 10 support approaches and the share of Windows 11-based devices continues to lag, Microsoft has reminded users that requirements for the new OS will stay.
In a recent blog post, the company said that the TPM 2.0 module is “not just a recommendation – it’s a necessity for maintaining a secure and future-proof IT environment.”
TPM is a dedicated chip or firmware that offers hardware-level security services for computers.
It houses encryption keys, certificates, passwords, and sensitive data and is tasked with cryptographic operations such as producing random numbers, encrypting and decrypting data, and confirming digital signatures.
TPM 2.0 also enables features like Secure Boot and Windows Hello.
Since 2016, the module has been a standard for all new Windows devices. However, many older devices don’t have it.
While there are some ways to bypass the requirement, Microsoft does not allow them, citing security reasons. One such workaround, which allowed Windows 11 to run without TPM by using the "Setup.exe /product server" command, was patched in August.
With less than a year left until the end of Windows 10 support on October 14th, 2025, it is still the most-used Windows version.
November Statcounter data revealed that Windows 11's market share, rather than gathering pace, actually decreased by around 0.5% to 34.94% compared to October.
After the official support for Windows 10 ends, Microsoft said it would allow users to extend security updates for one additional year for a $30 fee.
