Windows While newly minted Windows head Steven Sinofsky continues to play his cards close to his chest, we're seeing signs that Microsoft is rethinking its monolithic approach to not only the mass-market Windows operating system but the entire family of Windows products from servers down to CE-based embedded devices. First up is a streamlined microkernel codenamed MinWin, around which a re-engineered Windows line will be built. Described as 'the Windows 7 source-code base', in reference to the successor to Windows Vista which is slated for a 2010 release, MinWin strips back the current NT-based kernel to the barest of bare metal. Ars Technica has more, including a one hour video presentation [.wmv] about MinWin. Sassy quote of the day by Microsoft kernel engineer Eric Traut: "A lot of people think of Windows as this really large bloated operating system, and that may be a fair characterisation, I have to admit." My take: Maybe this will be closer to reality after all?

not slim at all

win nt used to run on machines with 24mb ram. i'm not quite sure what is supposed to be slim about this kernel if it needs 40mb without a gui. it's neither a microkernel by design nor a micro-small kernel by appearance.

nothing to see here, move along.

Say QNX?

"Nothing new here folks, now move along."

As a side note, it's amazing to me that Microsoft has the power to clobber it's faithful users with the cruft that Vista is, and yet, these same people should even care what what will be forced upon them in three to five years.

It's more about the tech then anything else.

It's always interesting to see what MS or Apple will do as they can popularize some radical concepts.

yeah, for real. Win 2k pro and XP pro can happily run in 45mb of ram if you disable a bunch of useless stuff. NT3/4 run fine in 24-32mb of ram.

I don't know for sure, but I would wager strongly that this is 40 MB of total virtual address space. There are probably many pieces that could be paged out without performance loss given RAM limitations.

"""

"""

The numbers are actually all shown in the talk.

39MB total physical memory
7MB free physical memory
37MB total paging file
8MB free paging file

So there is 76MB of virtual memory. 61MB of which was being used at the time the snapshot was taken.
