Preparing for Windows 7

I ran the Windows 7 readiness program and got the report. Among the things I’ve attempted to address (and it seems that I have to re-run the program even though I supposedly saved the report) is having My Calculator and Nero on this older laptop. Both show up in the Control Panel under Add/Remove Programs, but neither can be found to remove. None show up under Programs nor in Explorer. Finally, I went to the registry and found a bunch of items referring to Nero, so I took a chance and deleted them that way, doing a registry repair thereafter. I never found My Calculator. How do I find where that’s hiding/why that’s showing up under Add/Remove Programs?
