Because Windows 7 is no longer patched against modern exploits, keeping the environment strictly offline eliminates the risk of network-based intrusion and removes the functional necessity for perpetual online activation updates.

Consider using Windows 10/11’s Hyper-V or VirtualBox with a Windows 7 image from Microsoft’s “modern.ie” (now retired, but archived VM images for IE testing exist legally for compatibility).
