Yeah, and this is definitely a big reason why people are afraid to click and explore.

I still don't understand why big enterprise software still lacks any kind of version control. AUdit logs, yeah, but most big ERPs and other similar products don't have an easy "roll back this change" feature.

I think users knowing that they could immediately undo whatever they did and get back to a safe and known state would do a lot to encourage exploration and learning.

Not the same. ME also came out around 2000 but was based on windows 9x, windows 2000 was based on NT. The UI looked somewhat similar with those two.
