So long, Windows 7 calculator. You were quite the upgrade over the version that shipped with Windows Vista and older operating systems. You had a scientific mode that most people have no use for. My college professors wouldn’t let me use you instead of a TI 83. You also looked gaudy and didn’t match Windows 8. In Windows 8, you had a successor lurking on the Start screen, so we knew your days were limited. That day has arrived.
When Microsoft released Windows 10 Technical Preview Build 9926, they began removing many redundant features and suppressing others. The old Win32 calculator was one of the casualties. With a Modern version present since Windows 8, it’s an obvious move now that these apps can reside in resizeable windows on the desktop.
Don’t fret however, all the functionality of the old Calculator appears to be present in the Modern version. The only real issue I have is that the Calculator button on my Sidewinder X4 keyboard is bipolar about launching the app, but I’m sure this will be fixed in a later build.
