If you have a valid product key, get the ISO directly from Microsoft. If not, consider purchasing a modern Windows license or switching to a supported operating system.
Downloading the Windows 7 Pro ISO file was a smooth process. I was able to find a reputable source that offered a genuine and untouched version of the operating system. The download was quick, and the installation process was straightforward.
Microsoft maintains a legacy tool for customers with genuine keys.
Microsoft previously provided a “Windows 7 USB/DVD Download Tool.” While no longer supported, it can convert an official ISO from step 1 into bootable media.
