The minimum requirements for Windows 7 are modest by today's standards:
- 1 GHz or faster 32-bit (x86) or 64-bit (x64) processor
- 1 GB RAM (32-bit) or 2 GB RAM (64-bit)
- 16 GB available disk space (32-bit) or 20 GB (64-bit) -- just for the OS, not applications or data files
- DirectX 9 graphics processor with Windows Display Driver Model (WDDM) 1.0 or higher
- Internet access
As with any Windows-based OS, a faster processor, more RAM and ample free hard drive space generally mean a better computing experience. RAM is especially important. For example, upgrading the RAM from 1 GB to 2 GB on a 32-bit system should give the end user a dramatic increase in responsiveness and apparent speed.
Microsoft has an Upgrade Advisor tool to assess whether a system is prepared for a Windows 7 installation. You can obtain the Upgrade Advisor from the Microsoft Download Center, or visit the Windows 7 Upgrade Advisor Web page.
One of the essential differences between 32-bit and 64-bit systems is that a 64-bit computer lets you use more than 4 GB of RAM, which can be a huge boost for users who run graphics or CAD software, or multiple applications or multiple virtual machines (VMs) at the same time.
For best results, match a computer's processor to the OS. A 32-bit computer should run a 32-bit OS, and it can't run a 64-bit OS. However, you can run either OS on a 64-bit computer. If your 64-bit computer has 4 GB or more of RAM, and doesn't run older, specialized 32-bit software or drivers, go with the 64-bit OS to get the best performance.
To check a system for 64-bit capability, open the Start menu, right-click Computer and select Properties. The System section states whether you have a 32-bit or 64-bit operating system.
Note: You cannot easily switch between Windows 7 32-bit (x86) and 64-bit (x64). If you're using one and desire the other, your only option is to perform a clean, or custom, install.
Windows Vista drivers work in Windows 7, and Windows 7 provides more hardware compatibility than Vista. The new Windows 7 Devices and Printers applet displays icons for peripheral components connected to your PC -- just click an icon to access any device's settings. You can also use Devices and Printers to install non-Plug-and-Play hardware.
On the software side, Windows 7 should run most current software. In addition, Windows 7 XP Mode enables users to run applications designed for XP, extending the life span for legacy applications.
As long as a netbook meets the minimum hardware requirements, it can run Windows 7. Because most netbooks lack optical drives, you can run the Windows 7 setup from a USB flash drive or external optical drive.
