Now that you have upgraded to Windows 7, you will need to create a backup of your installation. One of the major reasons why I recommend you do this immediately after installation is to avoid some of the chores associated with reinstalling Windows 7. For instance, if your computer crashes or becomes unstable and you need to reinstall Windows, you will have to do a couple of extra steps if you purchased the Upgrade version of Windows 7.
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.
