If you have a Windows 8 Professional key, you can download to Windows 7 Professional for free if you meet a few other requirements. Otherwise, you'll need an unused Windows 7 key to downgrade. Regardless of whether you need to get an unused key or...
Check your version of Windows 8 to see if you qualify for downgrade rights.
"Downgrade rights" are designed for businesses and allow you to revert to Windows 7 for free. In order to use the downgrade rights, you'll need to meet a few requirements. The first of these is that you're running Windows 8 Professional. The computer has to have come with Windows 8 Professional installed out of the box.
Press ⊞ Win and type winver to see the version of Windows you are running. If you are using any version of Windows 8 besides Professional, you don't qualify for downgrade rights. You'll need an unused Windows 7 retail key to downgrade.
If you upgraded from Windows 8 to Windows 8 Professional, you do not qualify for downgrade rights. You'll need an unused Windows 7 retail key to downgrade.
Enable the legacy boot function in the UEFI settings menu.
This is required for computers that came with Windows 8 installed, but not for computers that were upgraded to 8 later. The UEFI is the interface that controls your computer, and is the modern version of a BIOS. Windows 7 doesn't support UEFI, so you'll need to set your UEFI settings to support the older BIOS method. The process is a different depending on your computer, but generally you can do this:
Press the ⊞ Win + C or swipe in from the right side of the screen to open the Charms bar.
Select "Settings" and then "Change PC Settings."
Click "Update and recovery," then select "Recovery." Click "Restart Now" underneath the "Advanced Startup" header.
Select "Troubleshoot" when your computer reboots, then "Advanced options."
Open the Activation window if it doesn't open automatically.
Windows 7 will attempt to automatically activate when you load the desktop for the first time and you're connected to the internet. If you used an unused Windows 7 key during installation, activation should happen automatically without issue. If you are using your downgrade rights, your automatic activation likely failed.
If the Activation window doesn't appear, click the Start menu, type "Activate," and then click "Activate Windows."
Call the phone number that appears if activation fails.
When you're using your downgrade rights, you'll need to call the Microsoft activation hotline and provide your Windows 8 Pro key to prove that you are allowed to downgrade for free.
Enter the code provided by Microsoft to activate Windows.
