If by refresh you mean rescan you shouldn't need to do that at all on the Pi - just do the scans on your Win7 client. All your clients should now be sharing a common library, so if one client is showing different recent movies there'll be a reason for that which probably isn't library related. If you're using one of my Pi OpenELEC builds be aware these have extra commits that allow you to hide watched items in the recent added Home widget, so you may be seeing different results in other builds (ie. x86) that don't have this functionality.
