Ok, so this isn't really too much of a big deal, but Eric Stott found a funny misspelling in the Import MSI Wizard which reminded of something I had noticed.

If you import or export an MSI and during the progress phase click the Progress item on the left list.

In the Export Wizard the "Results:" is blank and the top of the output says "label3"

 

In the Import MSI Wizard the "Results:" is some generic value and the top says "label1".

 

What is your easter egg?
