A possible useful FYI on installing Windows 11

Hello
I had being running Parallels and Windows 10 on a MBP for several years. I recently installed a fresh copy of my Parallels on a new MBP. Parallels gave the option of installing Windows 11, which I OK'd. It all took around 20 mins however Windows 11 was showing as unactivated. Despite entering a Windows 10 Product Key, Windows 11 decided that Windows 10 needed to be installed first. I tried installing Windows 10 from an iso but the iso was recognised as Intel and was rejected. It seemed as though I'd have to install Windows 10 ARM first. I started searching around uudump but, before going too far, I thought I'd try an old Windows 7 Product Key... it worked! This saved lots of hassle and downloading.
If you have an old Windows Product Key, it's worth a try.
