    There are many Windows 8.1 tablets and laptops that use compressed operating systems and have 16 and 32GB storage. I found the steps to install the Windows 10 Technical Preview on my HP Stream and it works, but it takes up a lot of the limited disk space. It was OK for playing around with it for a little while to see how Windows 10 works, but there is not much space left over since it isn't compressed like the factory image of Windows 8.1 was.
    When the final version comes out, is there going to be a way for end users to upgrade 8.1 to Windows 10 using a similar compressed format as Windows 8.1 was loaded at the factory so the Windows 10 upgrade doesn't use up of most of the available storage on these devices?

    I don't think they've mentioned anything about this yet, but considering they have made plenty of mention of tablets I don't doubt that there will be SOME equivalent.

    Did you have to do any trickery to get it installed on your Stream? I tried to load it onto my Toshiba Encore 2 a few weeks ago and got an error saying it can't install since it is a compressed operating system.

    To install Windows 10 on a system that gives that error, you have to download the ISO file and either burn a DVD or extract the files from the iso and make a bootable FAT32 USB stick.

    It worked for me, but the installation uses up most of the drive storage.

    Compressed OS is technically called "Wimboot". You can turn your existing installation into a Wimboot and thus free disk space.

    I'm still researching into this but the procedure would be as following:

    *Install Windows 10
    *Install drivers, updates and desired software to preload
    *Boot with a WinRE drive
    *Use DISM to create a WIM image of your system
    *Repartition the device with System reserver, UEFI, System and recovery partition
    *Store the created WIM image in the recovery partition
    *setup the system as WIMBoot

    Basically, that's what the manufacturer did to install Windows in your device

    It looks like this is going to get a lot easier soon:

    If you have to be walked through it, you shouldn't install the 10 Technical Preview as it is not a finished product and things can go wrong. Stick with 8.1 for now, unless you're feeling dangerous and have the ability to get your computer back on its feet if something goes wrong.
