Microsoft Considers "Instant On" Windows

Posted by timothy on from the catch-up dept.

Barence writes "In what might be a glimpse of things to come in Windows 7, Microsoft is asking customers whether they would be interested in a new 'Instant-on' version of Windows. 'We would like your feedback on a new concept,' the Microsoft survey states. 'The Instant On experience is different from "Full Windows" because it limits what activities you can do and what applications you can have access to.' Sounds interesting but hardly new: Asus and Dell have produced laptops that provide swift access to apps and data using Linux subsystems."

  1. Easy Lazy Instant-On/Off... by nweaver · · Score: 4, Interesting

    Boot the system. Now snapshot a memory image (a'la hybernate).

    Now for "instant on", set up the page table and start running, and in the background, lazily swap in the rest of the memory. Anything you need immediately gets paged from disk, and the rest of the state gets swept up over the next 30 seconds.

    Also, in the background, do "lazy write" as well: Any page that is stable for >X seconds but the disk is still active, write it out, so that going back to sleep (rehibernating) can be fast as well.

      Of course, if Windows hibernation operated anything like Linux hibernation, it would work a lot better.

      For reference, Linux hibernation doesn't bother writing non-writable memory pages to the hibernation file. So the hibernation file is much smaller compared to Windows. (Which is why Linux can hibernate to a swap file.)

      But this is because Linux can 'swap' from the original executable file into memory. So when it unhibernates, it 'unswaps' most of the programs from their original location, only loading the data segments from the swap file.

      Of course, a good portion of the program is already in swap, so what actually happens is that all data segments not in the swap file are written to it, with as much executable segments overwritten as needed to fit those in. It is very very fast.

      As opposed to Windows, which sits down and writes out all of physical memory to another file, and then has to load it all back in.(It might even write out 'clean' memory pages that are already in the swap file and unchanged since they were loaded back in memory, but I bet MS is smarter than that.)

      Granted, Linux still has to, eventually, load all the programs into memory too, but it can load them in via 'swap', which is fairly invisible to the end user.

    The green os. 12-18% better power savings for 'always-on' desktops. Sell it to the CFO, not the CTO, and leverage half the marketing budget to the Windows Green campaign. Don't bother with other features or capabilities. They are unneeded, and do nothing to drive adoption or deployment. (Sorry, feature teams.)

      You are forgetting the benefits of instant login machines. Instant on and instant login saves 5-15 minutes per day of user time. GEICO used to insist that their employees were logged in and ready to take calls when their shifts started. This got them a class-action lawsuit over the non-paid work and overtime accrued by their phone reps. (are your company's practices as unfair?)

    Because I have a secondary monitor to the left of my Microsoft Windows Vista laptop. Why is that an issue?
      - Because after undocking, Microsoft Outlook insists on opening on that (non-existent) monitor.
      - Because after re-docking, Microsoft Windows insists on logically placing my external monitor to the RIGHT of my Laptop, and swapping the screens that the start bar and sidebar show up on.
      - Because after undocking, carrying my laptop to the conference room and plugging it into the projector, all kinds of weird things happen.

    That's why I shutdown daily.

    Why does anybody turn their notebooks off?

    Windows Update :( Not "off" but restart.

    Hm. I run both Windows and Mac. I can't remember the last time I did any update to a Mac that didn't require a restart. It's really pretty annoying.

    Windows has gotten much better about not requiring restarts for updates. A huge change from its Windows 95/98 and NT days.

    I realize you're being sarcastic but I don't know who all these people are that are waiting 5 minutes for Windows to start. I've got both Vista and XP and neither takes more than a minute to boot, tops. If it's taking longer than that... maybe it's time for you to clean out some of the crapware you've got on there.
