I don't find anything wrong with the original Unlocker, but I always seek more up-to-date software and Unlocked development stopped in 2013. It works really well, but maybe something else works better? Whatever the alternative is, it absolutely has to have context menu entry/option.
I still use Unlocker. I still use Nero 8. I still use MyDefrag431. Just because they are old or have not been updated for ages does not matter. As long as they still work. Updatitis is an addiction.
