Take remote administration for example; Windows is incredibly open by default and yet getting this to actually work is surprisingly annoying. Everything about it annoying.
Powershell is a step in the right direction but Microsoft never found something they couldn't fuck up. Take the security modules: There are *85* cmdlets. Its bonkers.
But look at big tin for example, there is still no way - almost amazingly - to say "I would like this filesystem on that Raid Virtual disk thank you". You can't do it. It's not a use case. You can mount a volume on the filesystem but not anywhere useful.
The AD is out of our control, so you get bonkers things happening like the built-in admin account getting disabled via GPO, so you can't add yourself to the admin group on the server, and have to ask someone else to do it, FML
