Windows Whistler Beta 1

Windows whistler beta 1, an Operating system made from Microsoft that was intended to be in the middle of windows 2000 and XP, Windows Whistler had good drivers. Windows whistler was never meant to be public but rather a development testing Operating system to check what bugs there are to fix, Windows codename Whistler also has a buggy activation issue, meaning even though it'll say 'You have (0) days until to activate', it will stay buggy and not cause any issues when not activated since whistler cannot be activated due to it being an OS in the middle of NT 5.0 and 5.1.
