After a few seconds a window will tell you exactly which version of a program you have and if there's a newer version. AutoUP doesn't recognize every application, but the most important ones, like Skype, Chrome, Winrar, CCleaner or Adobe Reader, do fall under its radar.
Another thing that AutoUP lets you do is download some of those programs directly from its interface. You just have to go to the 'software' tab and click on any of the many available programs.
In another tab, the system tab, the program will give you information about your hardware, your operating system, and which screen you are using.
AutoUP is a very useful tool that could save you a ton of headaches. You don't have to search for the most recent version of a program any more. From now on, you just have to run this program and you're set.
