if as Malok suggests you have some 3rd party program changing this, the problem will recur.
If it does, try a clean boot, and then see if it still does.
If it doesn't, work back enabling startups until it recurs.

If it still occurs after a clean boot, Autoruns (free from MS) exposes more startups...
Thank you, I was able to change them back and they have not changed since.
