It's actually Windows 7 SP1 (build 7601), not RTM. This isn't a scam, those are legitmate Windows 7 Professional ISOs. You're completely wrong, you think you got scammed because of this? Try this in a VM and see. I will debunk people who did wrong in reviewing.

If you copied into USB, you can delete it.

If you burned it before in DVD, it's impossible to do this. You can edit the Windows 7 ISO with any ISO editing software and save it. Anyways, you can try in a real hardware, but if you have some of it, follow as Shadow Gaming does, as Windows 7 doesn't ship with USB 3.0 as Windows 8 did. And unfortunately, no more ESU updates for Windows 7, which is saddening, especially Chromium browsers, also you're forced to use Windows 10 which is terrible for old computers. 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.
