Windows 8 and Windows 8.1 System Requirements

NOTE: Windows 8.1 system requirements are same as Windows 8.

As we know Microsoft has released Windows 8 final RTM version to public and a free 90-day trial version of Windows 8 RTM can also be downloaded using following link:

If you are planning to install it but are not sure whether your system is capable to install it or not, don't worry! If you are using Windows Vista or Windows 7 in your system, your system will also support Windows 8 without any problem.

For those who want to know the system requirements, following are the official system requirements for Windows 8/8.1:

  • Processor: 1 gigahertz (GHz) or faster with support for PAE, NX, and SSE2
  • RAM: 1 gigabyte (GB) (32-bit) or 2 GB (64-bit)
  • HDD: 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
  • Graphics Card: 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 Modern (Metro) apps, you need a screen resolution of 1024x768 or greater
  • To snap apps, you need a screen resolution of at least 1366x768
  • To use secure boot feature the firmware should support UEFI v2.3.1 Errata B and should have the Microsoft Windows Certification Authority in the UEFI signature database

If you don't want to install Windows 8 in your system but want to test its new features, you can install it in a virtualization software. It'll not install Windows 8 in your system and will not affect your already installed OS. It'll install it virtually. Check out following article which contains instructions for installing Windows 8 in Virtual Box:

  • ...EXACTLY the same as windows 7. Impressive.
    (although the additional requirements differ)

  • Can anybody tell me what are snap apps in windows 8.

  • VG

    ^^ There are no snap apps. The line "To snap apps, you need a screen resolution of at least 1366x768" means that if you want to enjoy app snapping feature which allows you to run 2 Start Screen apps or one Start Screen app and one Desktop app side-by-side, you'll need 1366x768 screen resolution.

  • hello vg.. iam a regular follower of your blog.
    here is my doubt about installing windows8 release preview,when i tried to install it flashes a message saying'' your pc's cpu isn't compatible with windows8" but i am running on win8 consumer preview edition.

    my processor is intel Pentium 4cpu 3.00GHz,mercury 945 motherboard,with 2gb of ram..
    is their any thing i need to change in BIOS, to get rid of this message.

    thanks in advance.

  • Thanks vg for this info.

  • VG

    ^^ Welcome.

    Try to create a bootable setup disc or USB and then boot using it and install Windows 8 Release Preview.

  • ajay, maybe you are trying to install 64-bit version of Windows 8, and only few Pentium 4 CPUs are x64-compatible.

  • hmm, looks like every win7 PC can handle win8.
    will it fit on a 13 GB partition?

  • @ajay you need to enable a setting in bios, which says some thing like execute bit

  • @ajay, pls. refer to this link:

  • my processer is intel 2.40 and ram is 1gb ,hdd is 80gb then do not support wind8 they shows error please give me advice

  • @ Santosh
    There are many reasons, although ur system should support w8 as I have it running on much lower configuration.
    1) But maybe u r trying to install 64 bit version but ur config will support only 32 bit of windows.
    2) While creating bootable usb/dvd, some error might have occurred, in that case just reinstall it on the usb using windows 7 usb tool.
    3) The iso u r having might be corrupted so check ur iso or re-download.
