Although most large organizations use system images to allow rapid deployment of an operating system, settings, and applications to new computers, smaller organizations have a more haphazard approach to the management of desktop computers. Applications are often purchased and installed on an as-needed basis, and in many organizations, no two computers have exactly the same set of applications installed. This can make rolling out a new operating system challenging. 

If you perform clean installations for people, you need to make sure that you are able to install the unique set of applications that they had on their original computers. A large benefit of upgrading from one operating system to the next is that all user data and applications that were present on the previous operating system are present on the upgraded operating system. In this lesson, you learn about the conditions under which you an upgrade to Windows 7 while retaining all the applications and data that existed on the computer prior to the upgrade.

Sometimes it is necessary to upgrade from one edition of Windows 7 to another. For example, suppose that a small business has purchased several laptop computers that came with Windows 7 Home Basic installed, but they want to use the BitLocker feature and join the computers to the domain. Rather than just wiping the computers and installing another edition of Windows 7, it is possible to upgrade those computers to an edition of Windows 7 that supports the features the small business wants.
There are several advantages to performing an edition upgrade of Windows 7 rather than performing a clean install with another edition. The first advantage is that performing an intra-edition upgrade is cheaper than purchasing a brand-new operating system license. For example, upgrading to Windows 7 Ultimate from Windows 7 Home Basic is cheaper than purchasing a new Windows 7 Ultimate license. The second advantage is that you retain all applications and data that were already present on the existing computer
Windows 7 Professional contains all the features present in Windows Home Premium as well as some additional features; and Windows 7 Ultimate contains all the features in Windows 7 Professional, as well as its own additional features.


Windows 7 allows you to upgrade from one edition to another so long as that edition has more features. For example, you can upgrade from Home Premium to Professional, Enterprise, or Ultimate editions, but you cannot upgrade from Ultimate to Home Premium or Professional editions. Although it is possible to upgrade between editions of Windows 7, it is not possible to upgrade between versions of Windows 7. u cannot go upper version of window 7 to lower version of window 7.

You can use Windows Anytime Upgrade to upgrade from a 32-bit version of Windows 7 to a 32-bit version of Windows 7 and from a 64-bit version of Windows 7 to a 64-bit version of Windows 7, but you can't upgrade from a 32-bit version of Windows 7 to a 64-bit version of Windows 7 or vice versa.
For example, a developer in your organization has a computer with 4 GB of RAM and the x86 version of Windows 7 Enterprise installed. This particular developer does a lot of work testing application compatibility using virtual machines and needs more RAM. The x86 version of Windows 7 Enterprise supports a maximum of 4 GB of RAM. The x64 version of Windows 7 Enterprise supports up to 128 GB of RAM. However, it is not possible to upgrade the x86 version of Windows 7 Enterprise to the x64 version of Windows 7. It will be necessary to perform a wipe-and-load migration instead, backing up the developer's data and performing a clean installation of the x64 operating system before importing it onto the upgraded computer.
Alternatively, you could configure the computer to dual-boot between an x86 and an x64 edition of Windows 7 something made even simpler with the boot from VHD functionality that is included with the Enterprise and Ultimate editions . It is still necessary to migrate data between the two operating systems however. Migration is covered in more detail in Lesson 3, "Managing User Profiles.


You can use either of the following two methods to perform an upgrade from one edition of Windows 7 to another:

Upgrade using the installation media
Upgrading using the media is similar to upgrading from Windows Vista. You obtain the product key for the edition you want to upgrade to and then start an upgrade using the Windows 7 installation media. This method is most appropriate for organizations where a large number of intra-edition upgrades is required 

Windows anytime Upgrade 
With Windows Anytime Upgrade, shown in Figure 1-14,you can purchase an upgrade to an application over the Internet and have the feature unlocked automatically . This upgrade method is more suitable for home users and users in small businesses where a small number of intra-edition upgrades is required.

You can upgrade computers running Windows Vista to Windows 7. When you upgrade from Windows Vista to Windows 7, all documents, settings, applications, and user accounts that existed on the computer running Windows Vista are available when the upgrade is finished. The advantage to an upgrade is that it allows you to keep the current application configuration. When you perform a migration, you need to reinstall the user's applications on the new computer. As mentioned previously, this can be problematic in organizations that are not careful about keeping track of which specific set of applications are installed on each user's computer .

Prior to attempting to perform the upgrade from Windows Vista to Windows 7, you should run the Windows 7 Upgrade Advisor. The Windows 7 Upgrade Advisor is an application that you can download from Microsoft's Web site that will inform you if Windows 7 supports a computer running the current hardware and software configuration of Windows Vista. Prior to running the Windows 7 Upgrade Advisor, you should ensure that all hardware that you want to use with Windows 7, such as printers, scanners, and cameras, are connected to the computer. The Upgrade Advisor generates a report that informs you of which applications and devices are known to have problems with Windows 7. A similar compatibility report is generated during the upgrade process, but the version created by the Windows 7 Upgrade Advisor is more likely to be up to date.
