    According to those at Microsoft, you need the following configuration you can run Windows 7 on a PC:

    - 1 GHz processor or better on (32bit) or (64bit)
    -1GB Memory RAM (32bit) or 2GB RAM (64bit)
    -16GB free hard disk space (32bit) or 20GB on (64bit)
    - A DirectX 9 compatible video card with WDDM driver 1.0 or newer

    But we know that Windows does not eat as much memory as Windows Vista. So a PC with 512MB RAM or less can run the new version of Windows, well, someone has tried on a computer with only 96MB RAM. But if you try to install Windows 7 on a computer older than 4 years and has less RAM 512MB install will tell you that your memory is not sufficient, and Windows 7 installation will stop. Any ideas?

    1. Extract the ISO image files from Windows 7
    2. Download and install the editor dll, AptEdit Pro, or WinHex such
    3. Open the source folder winsetup.dll
    4. Search string 77073D7801
    5. Change it to E90400000
    6. Save and then close the application
    7. Recreate ISO image with new configuration and restart the installation.


    Does anyone else have another idea?

    Why not just get more RAM... it's dirt cheap nowadays! W7 will run a lot slicker for one thing!

    Yes, why don't you buy a PC with >512MB RAM? It's really cheap even you buy a OEM desktop comp.

    Cool. Thanks for the tip bud.

    I've got some old IDE Drives I'd like to use for Backup storage on my network. Only problem is my main system is SATA only. I do have a clapped out 10 year old system (500Mhz Athlon proc. 128Mb ram) As far as I know the memory is maxed out. It ain't gonna be fast but who cares all I need it for is accessing my IDE hardware via the network. Yes I could just use XP but i've not used XP in years and I'm accustomed to the Vista, Win 7 directory structure and control pannel.

    It'll be interesting to see how it turns out.

    You can do anything anything if you set your mind to it is that old saying...but it's not too "logical" to installing Win 7 with >512meg, sure it will run, but run as a old dog on it's last leg... ;) but more memory is worth it! ;)

    The 1gig is a "sweet spot" with Vista. You can tell a drastic difference change from 512.. ;)

    I would definitely recommend more RAM for your PC... Even if you were able to get Windows 7 installed on that computer, you would not have a good Windows 7 experience at all. Windows wouldnt have enough RAM and would have to constantly be transferring data from RAM to the page file on the HD, and vice-versa...drastically slowing your computer's performance.

    If I were you I would stick with Windows XP on that computer until you are able to get at least a gig of RAM in there (minimum). You will be much happier, or at least much less frustrated... :p

    Although without at least 512 you would enjoy no eye candy whatsoever, and have slow performance and lags so its not really worth it. That being said, "vlite" has the option to make it install vista (same for 7) with only 256 meg. You could use that program with only that option enabled and go from there.

    I think the win 7 RC will work but not the RTM.

    absolutely pointless ... there is a reason MS posted advised minimum specifications required to install/run Win7.

    yep, that about sums it up. :biggrin:

    Man, get a life. If you do not have a PC that meets the minimum spec then do not ask really pointless question!

    Well said... Spoken from a person who has life experience... In their time has assembled a collection of old PC's, but does not want to throw them away (why? they still work fine!).
    Yeah you really know what you are talking about!:worthy:

    Dudes... Maybe it's not really usable to run it on such a small amount of ram, but it's fun to try it. It's already said that he can buy more ram, so not everyone have to say it again.

    there is no way around it. Windows PE requires at least 512mb of RAM, without 512 PE will not boot.

    Windows Tiny 7 but it'll also run smooth on 1gb ram.. i guess..
    Note: Win tiny 7 is modded.. so, no guarantee for trouble..
