I've had to spend a considerable amount of time manually uninstalling each and every NI product from this machine after buying a new machine that will be music only.
I cannot for the life of me think of any valid reason for making uninstallation so painful.
Worst of all, the vast majority of them are sound packs that don't even need to be in the system registry ... and NI discontinued the tool they did offer in the past.
This is extremely inconsiderate of people's time, as it basically means we must spend an hour or so uninstalling each individual installation (most of which are just audio and patches).
I'm sure there are plenty of threads about this, but I don't think this can ever be addressed enough.
