My PC doesn't meet the requirements of Windows 11, and I still want to get the latest preview build of Windows 10. Before Windows 11 appeared, my PC had stayed in Beta channel of the insider program, thus getting a bit old preview build instead. Now I want to switch to Dev but this channel provides with Windows 11 at present so I can't stay here. Windows 10 Release Preview channel only offers a build 19044.1237, but I find Windows 10 latest preview build is 21390. So can I get this build and install it on my PC?
