Paul,
Yes, you have been lucky. It is my experience that most programs do not make a restore point on their own. You can break them up into three categories:
Those that do not. The majority of them.
Those that ask you if you would like one made. This should be the default.
Those that do and usually tell you during the install, i.e. "creating restore point."
If you are making a major change, I wouldn't rely on luck. I would manually create the restore point. I do not think that programs which do create restore points would name them in the System Restore feature. But, if someone knows other, please enlighten me.
By the way, although I am not a big System Restore fan, if you rely a lot of it, then GoBack is a much better program.
