Don't even change two settings in one software application at the same time. If it doesn't work, change it back and try something else. If it does work, then make the next change you're thinking of. Because they're in a hurry. People who are fairly expert at handling computers can live with this.
New users are likely to find it frustrating and discouraging.
So save yourself the trouble. Take only one step at a time. You gotta walk before you can tap dance. Spend a little more now, save a lot later. If you have to, get a little less computer in order to get these very important backup and safety resources.
