No, Microsoft does not allow installing Windows 11 on unsupported PCs.

Several reports suggest that Microsoft will eventually allow the installation of Windows 11 on PCs that are not supported. Unfortunately, these reports are false. A workaround is needed to bypass the hardware check in the Windows 11 installation program. 'No winning ads were found in the zone below the first paragraph. No winning ads were found in the introduction zone either.' Windows 11 has stricter requirements than Windows 10 and cannot be upgraded officially on PCs without an old CPU, TPM 2.0 support, or Secure Boot. There are alternative solutions, but they are not officially recognized and could potentially break at any time. Microsoft may already be requesting the ability to install Windows 11 on extremely old CPUs that do not meet the official requirements and require future updates to be installed on old systems. Microsoft has refused to lower the official requirements, even in the situation where free updates for Windows 10 end in October 2025. In fact, a few months ago, Microsoft published a blog post explaining why TPM 2.0 and other requirements are important, which seems to have closed the idea of upgrading old PCs officially. Some technology news outlets have reported that Microsoft has reversed its policy. The new Microsoft support document explains that 'there is no need to worry about encountering compatibility issues if Windows 11 is installed on unsuitable hardware.' However, the support document is not new. According to the Wayback Machine on the Internet Archive, the same warning was published in 2021.

There is no new policy. Windows 11 requires many old PCs to have authenticated CPUs, Secure Boot, TPM 2.0, and other hardware. The support document does not encourage or explain how to install Windows 11 on non-compliant PCs. There is no evidence that the official installer has been updated to skip these checks. If you are using a PC with Windows 10, we recommend signing up for the extended Windows 10 security or purchasing a new PC with Windows 11.

I will seek additional confirmation from Microsoft and update this article once I receive a response. There is no evidence at this time that Microsoft intends to change its stance.
