Do you have history calc code that come from win7 or winxp?

[UEFI-code]

Did the calc.exe come with winxp is written in pure cpp?

Can you push the history version code into a branch?

As mentioned in https://github.com/microsoft/calculator/issues/161, making older versions of calculator available isn't something we're working on right now, since we want to focus on improvements in this repo.
