How did it get that big? On my Windows 10, notepad.exe is 196 kB, I remembered it being under 100 kB, but it did get a few more features in the last years. Anyways, hard to judge considering that a good part of the original Notepad is likely to be standard Win32 components.

Anyways, none of these "mainsteam" apps hold a candle to sizecoding productions. Just look like what comes out of Lovebyte, a demoparty where no production is above 1 kB.
