The ideal update tool must first identify all programs on a PC, since only then can it work out which programs need updates and which ones don't. When it comes to the application recognition rate, SUMo leads the pack. The tool detects even the rarely used programs, for instance, Hex-Editor HxD. Though the HxD consists of only one EXE file, it does not install itself in the system. The excellent recognition rate of SUMo is the result of an extensive online database with about 90,000 different programs which are the most popular applications.

It identifies these programs on the user's system and then checks against the online list to keep a track of new versions and programs. Moreover, SUMo proves itself to be very flexible-for instance, the user can configure the tool in such a way that it scans practically the whole disk for applications. There is a drawback to SUMo, which is that it is only as useful as you want it to be. If you want something that takes care of the processing of dowbnloading and installing automatically, then SUMo is not for you since it requires that the user take the initiative after
the scan. The tool presents a list of all programs and specifies all the ones where an update is available.



After clicking on 'Update', SUMo directs the user to its website where it displays a compilation of statistics about which version is used by how many users. Unfortunately, a direct download link is missing, instead of which the user has to manually search for the updates, for instance on three popular downloading sites (MajorGeeks.com, FileForum and Download.com) or Google. Modifications of the program settings include loading at system start-up, disable checking of Microsoft products and beta versions, and scan speeds. To selectively check individual programs simply drag and drop the EXE (Executable) file of the application to the SUMo program window.
