Historically, digital distribution of Windows ISOs was facilitated by third-party vendors like Digital River. However, in the mid-2010s, Microsoft tightened control over distribution, requiring users to download ISOs directly via the Microsoft Software Recovery tool or the Visual Studio Subscriptions portal (formerly MSDN).
By 2021, Microsoft had actively removed easy access to Windows 7 ISOs for the general public. While Windows 10 and 11 VHDX (Virtual Hard Disk) images were readily available for developer testing on the Microsoft Developer website, no official QCOW2 images for Windows 7 were ever provided by Microsoft. This forced users into a dilemma: utilize the cumbersome process of converting physical media or ISOs, or turn to the grey market of pre-built images.
