Insert your portable USB drive into a free USB port. If you have USB 3 port (marked SS Super-Speed and blue inside) use this in preference to a USB 2 port to get a much faster backup.
Click Start button (Bottom LH corner) and select Settings Cog just above Power icon. In Settings select “Update Security” > “Backup” > “Go to backup and Restore (Windows 7) “. This will bring up the “Backup or restore” window below.
Click the Windows 7 Start button (bottom left corner) and type “backup”
After installing a new copy of Windows 7 SP1 the first Windows Update can take several hours “Checking for Updates…” and appears to be hung. However, don’t give up. It is processing over 200 updates! The time it takes to complete depends on the speed of your Internet connection and computer. Times can be up to 1 hr.
To avoid the frustration of waiting try to run this first update overnight. Ensure you have set Disk Sleep to “Never” within Control Panel | Power Options to avoid it sleeping mid-way through.
