We need an option in Services: "Restore to default"!
But if you go back to BlackViper and painstakingly go through each service, you should be able to get back to default.
It
is a pain though...
Btw. if you open a service (double-click it) there are four tabs.
Last tab shows what services it depends on and what services depends on it.
I'm using a mixture of BV's "Safe" and "Tweaked" settings.
You'll win a tiny, tiny bit in boot-up time with a "trimmed" system, but the nice thing about unused services is, they don't take up any cpu-time.
Normally I recommend people to leave them alone - or if you simply can not leave them alone, then at least take notes of what you change from and to...
But since you made a system image of the up-to-date-and-fine-running system, why not restore that and start again?
Should take you less than 5 minutes...
Good luck!
