If you're on Windows, download and run the media creation tool from microsoft. Pre-cracked/altered windows ISOs are not recommended at all. Note 2: We only recommend downloading and installing official/untouched Windows ISOs. It's essentially piracy with a middleman. You're not buying directly from MS so you're not buying a license, you're just buying a key and living on the promise that MS won't discover and deactivate it. This is not recommended, as these are grey-market keys, gathered from MSDN channels, each key sold multiple times ( extra reading). Note: Some people may recommend buying cheap keys elsewhere.
