Need for custom installation of Windows® 7
Why do you need a custom installation of Windows 7?
If your system is running with Windows XP, then you can upgrade it to Windows Vista or Windows 7. To upgrade your PC from Windows XP to Windows 7, you need to use the custom installation option. This process is different from the normal upgrade process in which all the files in the system will be preserved in the system itself. The custom installation of Windows 7 will not preserve any of the files in Windows XP. A custom installation is more complex, and it can sometimes take a couple of hours to complete. You can do a custom installation by following the instructions given in a Windows installation CD.
Following points are the details about custom installation of Windows 7:
- Need of custom installation
- Different ways for custom installation
Need of custom installation
Custom installation is the process during the upgrade of Windows XP to Windows 7. This type of installation will not preserve any of the files in the system. While you upgrade Windows XP to Windows 7, this custom installation is necessary. Otherwise the existing components in the system might be incompatible with the new operating system. Since custom installation removes all the existing components in the system, you don’t need to worry about an incompatibility issue.
Before you consider an upgrade of Windows XP to Windows 7 through custom installation, you should make sure your computer meets the minimum requirements. A 1GHz or faster 32-bit (x86) or 64-bit (x64) processor is the most important requirement for the custom installation of Windows 7. A minimum of 2GB is the memory capacity needed in the RAM of the system to upgrade from Windows XP to Windows 7. The required hard disk capacity for a custom installation of Windows 7 is 16GB. A DirectX 9 graphics device with WDDM 1.0 or higher driver is also needed to support the basic functions of the system. If you install an upgrade advisor of Windows 7 on the system, that will inform you whether the system satisfies all these requirements.
Since custom installation does not preserve any of the files in the system, you will need to move your files from the system before you install Windows 7. If the system consists of Easy Transfer, then this process will be easy and you need an external hard disk to move all these files. You will get proper instructions to install Windows 7. You can use the CD or any of the additional storage spaces such as USB to perform this custom installation process.
