The process of upgrading a computer’s OS can be quicker than performing a new installation. The upgrade process varies depending on the version. For example, the Windows 7 setup utility replaces existing Windows Vista files with Windows 7 files. However, the existing applications and settings are saved.
The version of an OS determines available upgrade options. For example, a 32-bit OS cannot be upgraded to a 64-bit OS. Another example is that Windows XP cannot be upgraded to Windows 7. Before attempting an upgrade, check the OS developer's website for a list of possible upgrade paths.
NOTE: Prior to performing an upgrade, back up all data in case there is a problem with the installation.
To upgrade the OS to Windows 7, follow these steps:

Step 4. Agree to the End User License Agreement (EULA), and click Next.
Step 5. Click Upgrade. The system begins copying the installation files.
