How can I uninstall this Winmaximizer? It won't let me. I want to remove it off my computer right now. Seems like no one can help me. How can I do it?
Try using Revo Uninstaller. Even if it can't uninstall the application normally, it will force it to uninstall by wiping out all traces of its presence from the system.
Although is not necessary, try running AdwCleaner to make sure that there are no leftover unlinked registry keys in your system.
