Windows XP build 2250

Windows XP build 2250 was released on 2000-07-13 at the Professional Developers Conference in Florida. This was the first build released to the testers and to be released in both Personal and Professional editions. Setup and many parts of the OS retained Windows 2000, Neptune, or even Millennium branding. It is the first build to be leaked in Personal SKU.

Changes
This build offered many changes in the GUI. This build also featured a completely changed HTML webview, including a task-based Control Panel.

Microsoft was quietly working on several hidden features. One of them being the Start Panel, an unlockable feature. It was going to be a replacement for the classic start menu. This build also featured a hidden active desktop-based Start Page, continuing the work started in Neptune.

Setup is now based on Windows ME and the banners are now replaced with the Windows Whistler logo, although the boot screen is still Windows 2000.

This build also is the first to no longer support the 486 processor, it will now only install on a Pentium or faster.
