Final straw for my private machine: I was not allowed to save in my own working folder. This was on a fresh out of the box install. I'm still angry. I switched to Linux full time after this.
I can not image how it must feel like when you are not having admin privileges. Given it is not a work machine, I would just refuse to go near it. No meditation would be enough to help me stay calm. My heart goes out to everyone who has to deal with this crap, I hope you get good money for it.
