I'm having issues too. I removed all the "getting started" type apps and it showed a few other random things but never seems to update. Most specifically, I open Word (from All Apps on the start menu) several times a week but it never shows up.

I prefer the Most Used over pinned apps because the thing I miss most about Win 7 is being able to mouse over a most used app, and see the recent files for that app. I want to be able to open recent Word docs, PDFs, Excel files, etc just by mousing over the correct application on the start menu.Sem
