Confirm your computer's compatibility with Windows 7. Microsoft recommends using the Windows 7 Update Advisor utility. This utility scans the computer hardware and the currently installed programs. Download this free utility from the Microsoft website and follow the installation instructions. Open the program, click "Yes" to the security prompt, and then click "Start Check" to scan your computer. The amount of time the scan takes to complete depends on the overall speed of the computer. Once the scan completes, you can review the compatibility report. The report informs you of any compatibility issues and provides recommendations on how to resolve the issues. You can run the report again after making any changes to confirm issue resolution.

Transfer your files to an external storage device. Microsoft recommends using Windows Easy Transfer, a free download available on the Microsoft website. Download Windows Easy Transfer and install on your computer following the installation instructions provided by Microsoft. Open the program, click "Next," and select "An External Hard Disk or USB Flash Drive." Then, click "This is My Old Computer." The program scans your computer. The amount of time this takes varies on the number of files and the overall speed of the computer. Deselect any user accounts you do not wish to transfer, and then click "Next." Enter a password, if desired, and click "Save." Browse to the desired external storage device and click "Save." You cannot use your computer during the file transfer. If you do not want to use Microsoft's free utility to transfer your files, you must manually copy your files to the external storage device.
