Repeatedly formatting my machine when it gets annoying has been an excellent way to practice backing up tools and settings for the large number of apps I use daily. I still wish a lot of these art apps were Windows Store apps -- having them associated with my account and taken care of by the store would make it so much faster and easier to install and configure all my favorite apps. The format has my machine performing better than ever, to the point where I've had to adjust to the faster capture of my drawings in Illustrator!
