Windows "The 16-bit Windows kernel was actually three kernels. One if you were using an 8086 processor, another if you were using an 80286 processor, and a third if you were using an 80386 processor. The 8086 kernel was a completely separate beast, but the 80286 and 80386 kernels shared a lot of code in common." As always, Raymond Chen delivers. If you don't yet follow his blog, you should.

siride,

"The fact that Windows can completely change its kernel and graphical implementation without breaking most programs written 20+ years ago is nothing short of an engineering miracle."

I mostly agree, but it hasn't been completely smooth. Some of the stuff I wrote in VB in the 90s stopped working. Of course the only reason I found out was because I was poking around my early career archive for fun. Someone would need to test a large sample of software from that era to assess how well compatibility has held up in general.
