I remember the guy who just decided to keep Windows 3.11 on a Celeron laptop, because it was awesome fast on that hardware (still perceivably faster than your Win 10 notebook perhaps), and he just worked couple of years that way, until some SSL problems forced him to leave Win 3.11. But business applications were ok for him in that environment. The very idea of a desktop app is that it should be able to deliver value completely offline, imho.
