What is an Upgrade Version
A Windows 7 Upgrade is a version of Windows designed to upgrade a PC that is currently running Windows XP or Windows Vista to Windows 7 – or a lower version of Windows 7 to a higher version of Windows 7. For example, if you have an older PC that is running Windows XP or Vista, or have Windows 7 Home Premium and would like to upgrade to Windows 7 Ultimate.
When you put a Windows 7 Upgrade version disc into your computer's CD/DVD drive, it will upgrade your current operating system. This can work in several different ways. Here are some examples:
If you currently have Windows XP installed on your PC and insert a Windows 7 Upgrade disc - It will upgrade Windows XP to Windows 7. However, your files, folders, and data will not be upgraded with the rest of the operating system. They will stay on your computer, but they will be moved to an unused location. After the upgrade completes and you have Windows 7, your XP files will be pretty much unusable. If you are doing an upgrade like this, you need to back up your files and folders to an external hard drive or flash drive.
If you currently have Windows Vista installed on your PC and insert a Windows 7 Upgrade disc - It will upgrade Windows Vista to Windows 7. You will have the option to carry all of your files, folders, and data from Windows Vista to Windows 7. After the upgrade completes, you will have Windows 7 and all of your stuff.
If you currently have Windows 7 on your PC and insert a higher Windows 7 Upgrade disc - It will upgrade Windows 7 to the higher version. All of your files will be saved and you will not lose anything from doing a Windows 7 to Windows 7 (higher version) upgrade.
Please note, a Full version of Windows (covered on page 1) is capable of doing everything that an Upgrade disc can do. Thus, if you insert a full version disc, you can upgrade from previous versions of Windows using it as well.
