What drive me crazy when using Windows for work is the abysmal copy/paste support.
Just 2 minutes ago I started an email, was composing a numbered list of steps, saw that a co-worker sent another email to the same thread, so I copied the text I was working on and replied to the latest mail.
The numbered list of steps was no longer a numbered list that I could continue auto-incrementing, but just plain text.
And that's just from one Microsoft program to itself. Copying text between two different Microsoft apps rarely preserves the formatting I want. Copying text between Microsoft and a 3rd party application is guaranteed to be an exercise in frustration.
On the other hand I cannot stand it when copy/paste preserves formatting. The last thing I want when I paste some text somewhere else is fonts, colors, hyperlinks, and numbered lists coming along with it. 90% (or more) of the time I just want the plain text.
