Hello,
There are two easy ways to do this, with the first option using Control Panel, the second option using WinRE.
The first option is to go to the Control Panel, and then once Control Panel opens, immediately under System and Security is "Backup and Restore (Windows 7)". Click that, and then under "Restore", the WIM file that was backed up to your external hard drive should be there. If it isn't, push "Select another backup to restore files from", and if prompted by UAC, run yes, and then select the WIM file that you backed up to your computer.
