: Indicates that the image was "repacked" with updates released through April 2017 . This is significant because Vista reached its official End of Life (EOL) on April 11, 2017 .
Many industrial machines (CNC routers, medical imaging devices, audio recording interfaces from the late 2000s) never received Windows 7 or 10 drivers. The 64-bit version of Vista SP2 shares the same driver model (WDDM 1.1) as Windows 7. If you have a device that refused to work on Windows 10, the "April repack" often strips out driver signature enforcement, allowing old .sys files to load. windows vista ultimate x64 sp2 final enu april repack
