Still, it is unclear if those techniques will work on shipping versions of the ISO. Enterprising enthusiasts are already finding workarounds to install Windows 11 on systems without TPM support (we're aware of a few already). The primary difference is that Windows 10 users can opt to use those features by enabling TPM, or simply choose not to use them. Microsoft's TPM requirement isn't popular, particularly because it doesn't enable any new functionality - all of the tech it enables already exists on Windows 10 systems that don't require TPM for installation. (Both countries have their own alternative encryption algorithms/technologies.) It's also conceivable that some systems without the TPM requirement could ship into other areas of the globe for other uses, so we're following up with Microsoft for more details. Microsoft's uneven application of the TPM requirement is probably designed to cater to countries that either forbid or don't use the TPM cryptoprocessor security functionality, like China (which receives its own special Windows builds already) and Russia, both of which don't use the technology for security reasons.

The company allows "OEMs for special purpose commercial systems, custom order, and customer systems with a custom image" to ship systems without TPM support enabled. Installing Windows 11 on a system without TPM enabled will require special approval from Microsoft. Microsoft lays out the full system requirements in its 'Windows 11 Minimum Hardware Requirements document ( Warning - PDF), with the sixteen-page document giving us a much deeper look at the nuts and bolts of the OS than the basic version (opens in new tab) Microsoft published previously.Īs we can see in the image above, upon approval, Microsoft will allow some systems to ship without TPM 2.0 enabled, meaning that it will obviously have either a special ISO for those installs or a method to bypass the TPM restriction during installation. Now the company has clarified that some systems will work without any flavor of the TPM cryptoprocessor enabled, which will certainly make the requirement seem superfluous to detractors. That requirement further restricts the number of computers that can use Windows 11. And for those that thought Microsoft would bend under public pressure over the unpopular new TPM requirement, the company has doubled down - At first, Microsoft only listed support for TPM 1.2 as the baseline, but it has since clarified that Windows 11 would only support the newer 2.0 revision. Windows 11 requires either a physical TPM key, resulting in an almost instant shortage of the devices and rampant scalping, or support for fTPM, excluding a large swath of relatively modern systems from receiving the update.
