What you need Upgrading from Windows XP
Upgrading your PC from Windows XP to Windows 8 requires a custom installation which doesn't preserve your programs, files, or settings. It's sometimes called a clean installation for that reason.
A custom installation is more complex, and it can sometimes take a couple of hours to complete. For complete details on installation instructions after purchase, please go to www.windows.com / Help & How to section.
- An external hard disk. You'll need to move your files off of your PC before you install Windows 8. To make this easier, we recommend a free download called Windows Easy Transfer, which will require an external hard disk. They're readily available at electronics and office supply stores, and they provide an easy way to add additional storage space to your computer.
- The original installation discs or setup files for the programs that you want to use with Windows 8. You'll need to reinstall your programs by hand after installing Windows 8. When you run Windows Easy Transfer you will get a report that lists the programs that you are currently using with Windows XP.
