A suggestion if I may. I'm a big fan of disk imaging software. I believe everyone should use it on a regular basis. Creating images to a second hard drive is the best protection against any and all problems that would cause you to have to reinstall the operating system and offers a simple method of restoring your system to an earlier date. It is better and more reliable than system restore and when used on a regular basis it is faultless. I image my system partitions on a weekly basis, keeping the two or three most recent images (and deleting the rest since they are very large).
The best such software is Acronis True Image, but it is not free. The best free alternative is Macrium Reflect. Might be worth looking into.
