Windows Vista 
For Windows Vista, the Windows Experience Index (WEI) is a useful measure of 
hardware level. The WEI is accessible from Computer > Properties, or from Control 
Panel > System. 
The recommended typical hardware requirements for the PC are: 
  WEI score of at least 3 in the 'Graphics; Desktop performance for Windows Aero' 
category. 
  Overall WEI score of at least 3 as recommended by Microsoft. 
  At least one USB 2.0 port 
  30 megabytes (MB) of free disk space. 
  Computer screen for use with the DisplayLink device, if it is not integrated. 
  Network access for software downloads, or access to a CD-ROM drive. 
If the PC specification is below this, performance will be lower (or CPU loading higher 
than acceptable).
