Update or reinstall? From Windows XP and Vista to Windows 7

    Being able to upgrade to Windows 7 from an existing Windows XP or Windows Vista usually raises a lot of questions and difficulties. Microsoft created a small tablet (see below) to clarify the situation, but it caused an even greater wave of misunderstanding.

    There are two types of installation indicated in the table, let’s dwell on them in more detail:

    In-Place Upgrade - updating an already installed OS. In this case, it will be possible to select the Upgrade option after booting from the installation disk or after running setup.exe from the latter inside the operating system. In this case, the installed programs and their settings will be saved.

    Custom install- a very vague concept and can mean anything. In this case, this means that you have to copy your data (via Easy Transfer Utility), format the hard drive, install Windows 7. After that, import the saved data and settings of your programs. By the way, this is the only way to transfer data and settings from 32-bit Windows to 64-bit. Also, this method is the most time-consuming and time consuming.

    I prefer installing on a preformatted hard drive. It is preferable to make a copy of the available information. The Windows Transfer utility copes with data transfer quite well, but God saves those who are safe. Windows Transfer utility also transfers the settings of installed programs and system settings (wallpapers, DPI, sounds, etc.); It works with most types of external media and network drives.
    With a large number of computers, in an office environment, useful utilities of a modern admin will come to the rescue: MDT and USMT. First, the Microsoft Deployment Toolkit 2010 allows you to customize the installation based on the specific needs of the organization. It is free and is in beta stage of development (work with Windows 7 is being added), in the future, you can distribute the installation over the network to one or thousands of computers using Windows Deployment Services or System Center Configuration Manager. Also, a modified installation image can be integrated with User State Migration Toolkit 4.0. The latter is a kind of Windows Easy Transfer utility, but at the corporate level. A special benefit of the User State Migration Toolkit 4.0 is that it is able to migrate data from 32-bit OS to 64-bit.

    Enough documentation and video guides have already been written on this topic, Microsoft will also touch on this topic at the TechDays 2009 conference series.
