    Windows 8 minimum reqs


    Ok I searched for this, and maybe im not searching for the correct terms, but anyone know what the absolute minimum reqs are for windows 8? i want to see if I can get it to run on a computer built for Vista but need to figure out the smallest hard drive I could cram this on and get away with...just for testing really...it works well on my main rig which was built for new systems and to be the power house anyways...I did also try checking the Microsoft site also, no luck...and yes what they have Im guessing are the reqs they say you should have, so im guessing those are the minimum, but im wanting to know if i could have less (yes i know im asking for slow arse system) and still get away with it, or if what they say is 100% minimum no less able to be done?


    • 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor
    • 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
    • 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
    • DirectX 9 graphics device with WDDM 1.0 or higher driver
    • Taking advantage of touch input requires a screen that supports multi-touch
    • To run Metro style Apps, you need a screen resolution of 1024 X 768 or greater

    Windows 8 is built on the rock-solid foundation of Windows 7, and it features many improvements in
    performance, security, privacy, and system reliability. Everything that consumers, developers, and IT pros
    have come to love about Windows 7 is still there – only better. Refinements to the kernel improve system
    responsiveness, security, and performance. Improvements in the driver model and tools chain for driver
    development improve system stability and reliability. And Windows now runs on ARM devices as well as
    x86 and x64. You’ll benefit from innovative security features and your apps run faster on Windows 8.

    Fundamentals

    System requirements
    Windows 8 works great on the same hardware that powers Windows Vista and Windows 7:
    1 gigahertz or faster 32-bit or processor
    1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit)
    16 GB available hard disk space (32-bit) or 20 GB (64-bit)
    DirectX 9 graphics device with WDDM 1.0 or higher driver
    Of course, taking advantage of touch input requires a screen that supports multi-touch.

    Apps run on ARM, x86, and x64 architectures
    In addition to running on x86 and x64 devices, Windows 8 delivers even greater flexibility by running on
    ARM devices. Depending on the technology you use, write your Metro style apps once and they can run on
    any supported architecture. You can also take advantage of the unique capabilities of your customers’ PCs.

    I don't know where the idea that either Windows 8 or 7 or maybe even vista need 128MB of video RAM to run the Aero interface pretty style. I tried this out one time with 7 and set my graphics RAM down to 32MB, everything ran fine.

    Sorry, I had to vent a little....

    OH! Also, does Windows really need that much space?! I don't think so, I've installed Windows 7 32 bit on 8 gigs of hard drive space and 9 for the 64 bit and I didn't need to vlite it or anything. Everything worked fine and all. I even have 32 bit 7 on a flash drive and it has all the drivers to install on systems. So why does Windows need that much space?!

    I've noticed a sizeable increase in the Windows installation size from 7 to 8. I could usually get 7 on 9GB but I have to have at least 13-15GB if I want 8 to install properly... Bummer.

    Hmm, that might be something different with 8. Since there's no Safe Mode for Windows anymore, there might be more critical system files in Windows' bank of files that are used in case if the operating system cannot load up. But then again, what are we supposed to do without Safe Mode?

    Hm, yeah, and what will that mean when we realise that the first thing to do in the event of a system failure is to boot into safe mode? Maybe they will have a sort of restricted mode?
    There must be some reason as to why they need the extra hard drive space...

    Speaking of such, I just had to do a startup repair, or it's now call automatic repair for 8. It's quite odd because it's so different. It has an old-school loader saying loading automatic repair files, then it goes to a boot screen saying detecting errors, then something like performing automatic repair. Then it restarts and it's all good.
