Since my comment above I have discovered this.
Rufus is a utility that helps users create bootable USB drives to install Windows 11, including on unsupported hardware. To use Rufus for this purpose, you can either download the Windows 11 ISO file directly through the tool or provide an existing ISO file. Rufus allows you to bypass hardware requirements such as TPM 2.0, Secure Boot, and memory requirements, enabling installation on machines that do not meet Microsoft's official criteria.
I haven't provided any links to Rufus, as I would hope that if you were going to do something like this, you would be able to find it yourself.
The lack of response to this thread makes me wonder how many people are actually aware of the implications of being unable to upgrade to Windows 11.
After 14 October 2025, Microsoft will no longer provide free software updates from Windows Update, technical assistance, or security fixes for Windows 10. Your PC will still work, but they recommend moving to Windows 11.
I do recall reading somewhere, I can no longer remember where, that it will still be possible to pay for regular security fixes.
