Our Review:

My favourite software update monitor is KC Softwares' SUMo, which stands for Software Update Monitor and it may be the best software update monitor for expert users. It's faster than Flexera's PSI, but slower and requires more bandwidth to check for updates than FileHippo App Manager (FAM).

During a normal scan, SUMo will search your start menu for a list of programs, while a complete scan checks your "Program Files" folder, yielding more results that may require some selective elimination. SUMo also lets you decide whether or not you want to be notified about Beta software.

Another feature that you may or may not like about SUMo is the result you obtain by clicking on the "Update" link for new software. Whereas PSI and FAM take you directly to a download page, SUMo takes you to a webpage with usage statistics about recent versions of the program, and displays the number of users who use each version. Although that may be interesting, there is no direct link to a download page. SUMo's page gives you links to five major download sites' search pages (which sometimes do not work with the information supplied by SUMo) and a link to a Google search for the software. However, by not being restricted to a database of downloadable software, the SUMo database can support any software its users report.

The advantage of SUMo is that it informs you of updates to software that is not limited to security updates (such as PSI) or availablity on FAM. It also lets you add or remove programs to the list it scans for updates by simply dragging the executable into SUMo's open window; a feature not available on any other software update monitor (FAM allows one to add folders to the search space).

Unfortunately, some developers do not include version information in their binaries which makes it impossible for SUMo to detect updates for them. This is a problem for most software update monitors. Unfortunately, when SUMo performs its first thorough scan it detects executable files that may not be the main executable files of your installed software. Experienced PC users should therefore take care to add the executable files that should not be checked for updates to the ignore list. Once this has been done, the unwanted executables will not appear in future scans.

WARNING: Should you decide to download SUMo, get the "Lite" installer or even better the zip version, the safetest to use without adding any unwanted software. The "Regular" installer may contain a program called Relevant Knowledge, which is detected by most security software as spyware.

I've regularly used Sumo in the past and found it useful to identify out of date software on my system. Yesterday I've updated it to the latest version. Now it not only generates false positives, but also, when trying to download updates for claimed out-of-date software, it jumps to the Mycommerce website which places an order for for a Sumo lifetime license in its basket. If one is observant then the order can be cancelled, if not one will end up paying £28.06 for an unwanted and unnecessary Sumo license.

The first annoyance you spot is that the premium only functions are not hidden, they just get you a pop-up box encouraging you to register. The second is that pretty much everything is a premium feature. The third is that whatever you click gets you to a page asking you to buy. The worst, though, is that once you go to the page with the update links on it (either a Google search or links to MajorGeeks and Softpedia), there is a very prominent link that says "Download Software X". Now, you would think that would go direct to the download of Software X, but, no, takes you yet another purchase Sumo page. So although Sumo is very good, it is just far too annoying to use
