After using the new Windows 8, do you want to go back to Windows 7? Maybe you work in a large company that doesn't want to use both systems. Microsoft doesn't facilitate this process, but you can get back to Windows 7 from Windows 8 by following the steps below.
Steps
Method 1 of 2: Downgrade from Windows 8 Pro
Step 1. Get the DVD or USB stick and a valid product key for Windows 7 Professional
It doesn't have to be a new Windows 7 key, but it needs to be valid so you can use it even if it's installed on another device.
- Call your PC manufacturer and ask for installation discs for Windows 7 Professional. Since many manufacturers keep disk images of the computers they sell, with the correct drivers for each PC, they should generally be able to give you what you need.
-
Download the ISO (optical) image and burn it to a disc, or order the disc itself.

For most computers with Windows 8, the best choice is Windows 7.
Step 3. Follow all downgrade steps described above, except activating the downgrade, including backing up all personal files and applications
