To assess the readiness of client computers for Windows 7, you can use the Microsoft Assessment and Planning Solution Accelerator, a centralized and agentless tool that can remotely inventory computers, identify their supported Windows 7 experience, and recommend specific hardware upgrades where appropriate. For more information on this tool, see "Microsoft Assessment and Planning (MAP) Toolkit" found at http://technet.microsoft.com/en-us/solutionaccelerators/dd537566.aspx.
