In certain scenarios you may need to restore your Windows 7 Computer back to the previous installation of Windows. This article walks you through the steps to manually restore your computer back to the previous version of Windows.

Note: To do this, you must use the command prompt, and you must type specific commands at the command prompt to rename and to move folders between the different versions of Windows. 

Note: If you currently have Service Pack 1 for Windows 7 installed, the uninstall steps are the same as with Windows 7 without any service packs installed. If you are restoring back to a previous Windows 7 installation, you may need to Install Windows 7 Service Pack 1 to that installation.
