Just do what I do. Make the computer boot directly to the desktop. Use some programs to make it look similar. Then you'll have a more modern faster windows 7 with longer support.
If you really want to back up all your data (DON'T use one of those programs, just drag and drop the important files to an external hard drive). I suggest putting really important files on a usb drive or something as well just to be totally sure.
Then you'll need a blank disc or a usb drive, and a windows 7 iso downloaded from online. You'll burn the iso to the disc or use a program to make a bootable iso on the usb drive using the file.
Turn off your computer, turn it on and quickly spam the number keys that let you boot into the BIOS. Use the arrow keys to navigate to the page where it lets you either change the boot order, or force boot a device. Then make sure you're set to boot from the usb or disc.
Once you do that you'll be guided through an installation, where there are options to format the hard disc. Do it, and let windows 7 install. Make sure you run all the windows updates or you'll be missing drivers.
Move all your files back over. Done. Crack if you don't have a key.
