Windows Whistler Beta 1

Windows Whistler was the pre-release codename for Windows XP, or NT 5.1. It is the successor to Windows 2000. XP was the first that did not compete against a DOS based version of Windows, effectively finally unifying the Windows line in to a single pure 32-bit product. Below are various Beta releases. Winworld does not host the final RTM versions.

Please be aware that there is risk of acquiring malware if you connect these to the internet or browse with the old versions of IE.
