• Robert had for a few years, returned to me for repair. No power supply so I made one with parts
• Had Microsoft Vista installed
• Intel Centrino Duo

Installed Windows 7 Home Premium on it, D3WTY-4HRKW-T3BQY-KK78P-VKF2D (3/9/2016).

3/10/2016 Right after installing Windows 7, but before Authorizing it, received a window offering to download Windows 10. Did this, but it asked for a Product Key, so had to cancel setup. Probably because underlying Windows 7 was not authorized.

Panel showing DVD features, etc., is illegible at this writing (3/10/2016)
