Proto:Windows XP

From Misc Data Digs

This page details one or more prototype versions of Windows XP

Windows XP became the most popular version of Windows. It was built on top of Windows NT technology and forever moved Windows away from the DOS-based kernels of the 9x era. With this, there is a lot of interesting history behind how it got there.

Build 2211 (March 2000)[edit | edit source]

  • A log-in screen leftover from Neptune is still present in the data.
  • Some select features, like the control panel, are ported from prototype builds of Windows ME.

Build 2223 (April 2000)[edit | edit source]

  • ClearType is now present.

Build 2250 (June 2000)[edit | edit source]


  • The Professional/Watercolor theme is enabled by default in this build. Notably, there's a window state for windows blocked by a modal dialog. When this happens, the windows turn red.
  • This is the first build to require the Pentium Pro, as a result of removing the emulation for the cmpxchg8b instruction from the kernel.
