Windows Earlier today, OSNews ran a story on a presentation held by Microsoft's Eric Traut, the man responsible for the 200 or so kernel and virtualisation engineers working at the company. Eric Traut is also the man who wrote the binary translation engine for in the earlier PowerPC versions of VirtualPC (interestingly, this engine is now used to run XBox 1 [x86] games on the XBox 360 [PowerPC]) - in other words, he knows what he is talking about when it comes to kernel engineering and virtualisation. His presentation was a very interesting thing to watch, and it offered a little bit more insight into Windows 7, the codename for the successor to Windows Vista, planned for 2010.

Nothing speaks against a completely new main subsystem, keep the old one running side by side for "legacy" applications. Glue put where needed (i.e. windowing).

The NT kernel indeed allows for subsystems (up until Windows 2000, for instance, it had an os/2 subsystem), but would you really want to run the entirety of win32 in an NT subsystem?

One of the prime points in these two articles of mine is that you really do! not! want! to ship/run the current Windows userland, because it is a mess - if you move it to a subsystem, you do just that: you move it to a subsystem. You're just moving it around, you're not sandboxing or isolating it.
