Migrate Your Data From an Old Computer to a New One

When you buy a new computer, you start with a clean and clear and empty, which is great, but you don't have any of your documents or settings from your old computer. Luckily, it's very easy to transfer all your files and settings from your old computer to the new one—whether you're on Windows / Mac.

MIGRATING FROM WINDOWS TO WINDOWS WITH WINDOWS EASY TRANSFER

Windows 7 has a great tool built-in called Windows Easy Transfer, that can grab your data from an old computer  even one running Windows XP  and transfer it to your new machine with an external drive. To set it up, plug in your external drive and hit the Start menu on your new machine. In the search box, type "Windows Easy Transfer" and click on the shortcut when it pops up.

If you are running Windows XP, you will need to install the Windows Easy Transfer files to your external hard drive first. Hit Next at the first window, then hit "An External Hard Disk or USB Flash Drive". Then click "This Is My New Computer" and hit "No" at the next screen. Click " I Need to Install It Now " and pick your external hard disk when prompted. Windows will copy the necessary files, which should only take a minute.
When it's done, unplug it and plug it into your old computer. If you don't get an autorun prompt, head to My Computer and double-click on your external hard drive. From there, it will ask you if you want to install Windows Easy Transfer on your Windows XP machine. After it does, it will scan your computer for data to transfer.
Select the users you want to copy over and hit Next. Save the data to your external drive or flash drive and wait for it to transfer ( this might take awhile ).
If your old computer is running Windows 7, you can skip all the above steps and just open Easy Transfer directly from the Start Menu's search box and picking " This Is My Old Computer ". It will then perform the above steps and transfer your data to the external drive.

Once you have moved your user data from your old computer to the external drive, head back to your new computer and plug the external drive back in to your new computer. If you closed the Easy Transfer Window, open it back up and navigate through the steps again, this time picking " Yes " when it asks you if Windows Easy Transfer has already saved your files to an external drive.
Select your drive from the list and check the users you want to transfer over. Wait as it transfers all your data (again, this could take a few minutes). When it's done, your computer will restart, and you should see that all your files and settings are available on your new machine.
Note that this won't migrate any of your programs, just your settings and documents. It will, however, let you know what programs you had on your old computer so you can write down a quick list of the programs you'll want to reinstall.
