To be honest it's unlikely that all this information could be lost; in my experience it takes a hard disk failure to lose everything. I've had corrupted boot sectors before and managed to recover all the data, it was just a pain having to reinstall all the programs again.
I recall I had an issue with the last big Windows update where the first attempt to install fell over; when it went OK the second time i thought it was all OK, but it must have mucked something up. I can say that it now runs faster than it did pre-restore, so it definitely fixed something.
Perhaps instead of worrying about a fancy backup, you just manually copy anything you really can't replace to somewhere safe like the cloud or DVDs and then give it a go.
P.S. I ran Services.msc; all the items that were disabled (about a dozen for me) were non-essential; most would just lengthen boot time as they check whether they need to update programs. About half the rest are manual, which looked in many cases as what this means is that they are triggered by something. I saw no need to change anything.
