A little off topic but I use a disk image program it creates an image of your hard drive. you can restore it anytime you like, it does a complete restore erases and overwrites the drive back to the date you saved the last image.
It is almost automatic tell it to do an image and walk away in an hour it's done.
You'll never have to reinstall windows or any programs.
I use it before I change anything on my computer that way if it doesn't work tell it reinstall and walk away in an hour it's like it never happened. It even works if you have to swap out a new hard drive in case yours fails.
It will also boot from a cd to restore your computer.
Best 75 dollars I ever spent. I save to a usb drive,, I have a back up of the computer when it was new and further down the line as I installed programs and they were working right I made other images.
