unsintalling SP!

I've been reading most of the threads here about SP!. I didn't remove all my add ons before downloading SP1 and I'm noticing a couple glitches that weren't there before. Overall I'm happy with what I see, I just want to see if removing all my add ons first and then installing SP1 will make a difference.

How do you remove SP1?

this wasn't a joke. I honestly do not know to unstill SP1 so I can do the whole procedure correctly.

Try this it works.

And clean the registry!

I didnt see what radarman posted but you can always just reinstall fsx. Save your addons though unless you havent but the post above might be a quicker way.
