You can download every single windows ISO and they come direct from microsoft servers (tech bench).  They're not even restricted, password protected or anything like that, MS just buried them on their site so they're not that easy to find them (cuz they want you to use their Media Creation Tool).  The heidoc app just makes it easier as it's got the links to every ISO but you could just find them yourself on microsoft download servers if you took enough time to look hard enough (just use the heidoc app).

Are people just supposed to believe you that they're 'excellent, clean ISOS'?  Why, because you said so? lol

Takes 5 min to find the source of all windows ISOs from where they are open and free to download on their website.

You = idiot for trying to sell windows ISOs and claiming they're 'excellent and clean' haha and hosted on mega.nz at that lol you made my day.

Just go download them from MS website ... duh .. you don't even sell keys, which is all that matters anyways lol foolish.
