The Minimum Requirements for Windows 7 Home Premiumby Ann Frederick
If you're considering an upgrade of your computer's operating system, Windows 7 Home Premium ranks among your options. The system requirements to install it depend on whether you'll use the 32-bit or 64-bit version. Microsoft says the 64-bit version can provide more efficient operations if you run and switch between several programs at the same time. You'll get the most benefits out of this version if you have at least 4GB of RAM, although its system requirements for installing this version are below that threshold.
Memory, Processor, Video Card
You need at least 1GB of RAM to install the 32-bit version of Windows 7 Home Premium and 2GB to install the 64-bit version. The processor speed required for both installations is 1 GHz. Windows 7 Home Premium requires a DirectX 9 graphics processor with a WDDM 1.0 or later driver. You may need more advanced graphics hardware and additional memory for video playback of some files.
Hard Disk Space
Make sure you have at least 16GB of available disk space if you want to install the 32-bit version of Windows 7 Home Premium from a disc. You'll need 20GB of room on your hard drive for the disc-based 64-bit system. Add 3GB to these totals if you plan to download the operating system instead of installing it from a disc.
To take advantage of the CD and DVD authoring tools available in Windows 7 Home Premium, you'll need an optical drive. Some features of Windows Media Center may require you to add a TV tuner and additional hardware. You can download and run Microsoft's Windows 7 Upgrade Advisor to confirm that your computer hardware, software and devices will be compatible with it. The advisor can give you recommendations on changes you need to make before upgrading.
