System Requirements
1 GHz or faster processor
1 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
For Metro Apps
One new element to Windows 8 is the requirement that Metro style applications have a minimum of 1024x768 screen resolution, and 1366x768 for the snap feature. If you attempt to launch a Metro style app with less than this resolution (e.g. 800x600, 1024x600) you will receive an error message.
Virtualized Environments
Our recommendation for the Consumer Preview is to run it natively on hardware if you intend to run Windows 8 on hardware when the product is final. Some of you will run virtualizedenvironments for enterprise workloads or specialized purposes, but we strongly recommend that you experience Windows 8 on hardware, as it was designed to run for the majority of consumer experiences.
For Touchscreen Users
Although there are a number of existing Windows 7 touch devices and many are fully supported, we do recognize the touch experience of Windows 8 places a greater demand on a high quality experience than could have been foreseen when manufacturers were developing hardware for Windows 7. Our data is showing that a vast majority of Windows 7 touchscreens will perform well for Windows 8. This means that touch drivers continue to load, and you’ll be able to perform basic touch interactions with a reasonable degree of success. The following systems are a few that we have been using widely in our internal testing and self-hosting, although of course, this is not a specific endorsement of these PCs:
- HP Elitebook 2760p convertible (Note: This PC is 1280x800 and so does not support snap.)
- ASUS EP121 tablet (Note: his PC is 1280x800 and so does not support snap.)
- Dell Inspiron Duo convertible
- Lenovo x220t convertible
- 3M M2256PW 22” display (Note: The raised bezel can make it harder to swipe along the edges)
- Samsung Series 7 slate (Note: This PC has two models, one was provided to attendees at //build/ and the other is a commercial release; the latter has slightly different peripherals and firmware.)
Specific Hardware Requirements
(Note: be careful whenever you adjust your BIOS settings.)
- Secured Boot requires a new UEFI BIOS, which is not available broadly on PCs yet, but is starting to be made available. If your machine does have UEFI, you can enable it via BIOS settings.
- BitLocker does not require but performs more seamlessly if your PC has a Trusted Platform Module(TPM). Machines that have this sometimes require it to be enabled via BIOS settings. BitLocker To Go requires a USB flash drive that meets performance criteria evaluated at installationtime.
- Hyper-V requires a 64-bit system with second level address translation (SLAT) capabilities and an additional 2 GB of RAM. You can also enable SLAT via a BIOS setting.
- Some games and other software require graphics capabilities compatible with DirectX 10 or higher (including some games available in the Consumer Preview and in the Windows Store. We will continue to improve the verification of your system prior to downloading or running software with these requirements). Some games and programs might require a graphics card for optimal performance.
- If you clean install instead of upgrade (see below), you should check your PC manufacturer's website to make sure you install any specific drivers that they provide there. Many laptops will get better battery life with a power-optimized driver that is specific for that PC (often known as ACPI, Power, or Chipset driver).
