And especially 圆4 is which I can get all the job done with Windows 7. I used this in my 41-in-1 project, so 5 stars. If you delete ei.cfg, you will gain access to other editions as Ultimate, Professional (it is mentioned), Starter (x86 only), Home Premium and Home Basic. It's a legitimate ISO for both Windows 7 versions. This version is so useful and it is better than Windows 10.
