Windows 8 for me, unless your using a touch display not much point having it as a desktop OS. I had to find ways to a start menu working on the OS so i can use it effectivly

For me it was "FVWM95"...I had come from the dos/windows world and this early windows manager in redhat 5.2 made me tear my hair out until I got the hang on things...

On the plus side,my favorite is still BeOS...

Since Microsoft Bob and Windows 8 desktop has been taken I'm going to go with:

Blender: Pre UI change.

When someone mentions bad ui, blender is my first thought!

Oh wow, I'd forgotten about that.

Bob is definitely the worst though. That took skeuomorphism to an absolutely insane level.
