But yeah, know
that situation all too well.
A loooooong time ago, I worked in a place that went to the trouble of providing useful tools (mostly follow-the-bouncing-ball screencaps) for users to show them how to make various changes to their PCs - pick desktops, relocate icons, change colour schemes, etc. Mostly harmless stuff that gave them a sense of ownership of their PC. By giving them this knowledge, we "empowered" them...the wording of the day.

Anyway, 80% of our users were happy to leave the PCs bog-standard and get on with the job. About 15% liked to use the vids to personalise their unit. And thus it was only the 5% remaining who were the real problem-children. Consequently we could then concentrate on them, why they had problems, and find useful solutions for them (sometimes involving taking the damn PC off some of them because they would also have a problem driving a spoon).
