The most stable Windows 95 installation I ever had was a 486 Vesa Local Bus PC. I had such a beast at work for several years, initially with DOS and Windows 3.1, but I got to upgrade it to Windows 95 during our first forays into supporting Win95 on the LAN, at the time, Banyan VINES.

I never had to re-install it. Ever. And it had numerous beta-issue Windows VINES drivers installed and de-installed. I suspect Microsoft had just such a platform in abundance for developing and testing on. Hence the stability.
