Windows 7

I've just upgraded my system from Vista Ultimate to Windows 7 Ultimate. And as for now everything run so fine.

Although the look of Windows 7 may seem to be nothing more than some polish applied liberally to the Vista Aero theme, make no mistake: this is a full replacement operating system, and more than just "Vista done right." From driver support to multitouch groundwork for the future, from better battery management to the most user-friendly interface Microsoft has ever had, Windows 7 is hardly half-baked.

If you want to run Windows 7 on your PC, here's what it takes:

• 
  
  1 gigahertz (GHz) or faster 32-bit (x86) or 64 bit (x64) processor
  
  
  
• 
  
  1 gigabyte (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
