My uninstall module tab is almost empty hello to the drupal pro,

I have over 50 disable modules listed on my module list page but only one appear under the uninstall tab. (Toolbar module)

I discovered that when i wanted to uninstall a module for the first time

Any idea why?

PS: i'm running my drupal site on the localhost using WAMP server
Modules only appear listed on the uninstall tab if they have been enabled and then disabled at some point in the past, AND if they actually installed something in the database that can be uninstalled (i.e. custom tables, variables, etc.) OR they implement hook_uninstall, even if they don't install anything in the database.
