In Windows 7, the Windows Team has added improvements to networking and sharing data among multiple computers in the home. You can easily share information and resources such as Documents, Pictures, Music, Videos and Printers with just a password.
If you have decided to upgrade to Windows 7, you have one other thing to to do, choose an edition. This will depend on a number of factors, whether you are doing a clean install, upgrading from a previous version of Windows, or you have multiple PC's in your home. Microsoft has made choosing an edition of Windows 7 a little easier in comparison to Windows Vista. Instead of 6 editions, you will now see 3 editions in mainstream markets. Cost is also a factor and users need to evaluate their needs.
