Advanced Uninstaller PRO then monitors the installation and what happens the first time you start the new application. To do this you must start it before you run the application setup program, so it can take a snapshot of the system state. But it's annoying if you really want to uninstall the program, and even more annoying if you later decide to give it a second try and find that you can't because the original trial period has long expired.Īdvanced Uninstaller PRO allows you to remove applications cleanly and completely. This is to stop people uninstalling and then reinstalling when the trial is up, to avoid purchasing. Uninstallers often don't remove installation dates or usage counts that are used to limit the use of trial versions, either. But the effect is that your computer fills up with traces of every program you have ever tried.

The reason is so you can uninstall and reinstall a program to upgrade or fix a problem without losing your settings. It only undoes the changes made during the installation itself.

The standard uninstaller that comes with every Windows application does not remove files or registry settings created when you run the application.
