Calculator is a bootleg Windows XP SP1 edition, which was created by ziad87. It released on May 15, 2021. It was made as a test recompilation of the XP source code. For some reason, it was added to the collection in December 2021.


This bootleg was simply a recompilation experiment. The bootscreen has been changed and everything has been stripped out and replaced with Calculator.

Changes from Windows XP SP1

Changes in pre-desktop procedures

  • The bootscreen has been changed.

Look and feel

  • Almost everything has been ripped out. Calculator is the only program you can run and use.


Bootleg quirks

  • The blue screen of death (BSOD) has been changed. It is now black, and says "Windows encountered a problem >w<" instead of "A problem has been detected and Windows has been shut down to prevent damage to your computer."
