Since you mainly use File Hippo, I am going to guess that you have it's "Update Checker"! I did not install it but have the
free standing version. It is the best I have seen since cnet and norton pulled a file called "CatchUp" almost a decade ago. Not seen anything as good and quick and light until Update Checker

The differences are
Update Checker only checks for recent releases and betas on files that are on the File Hippo HD.
CatchUp linked you back to the software authors site for the download , so more program updates were available.
There are many programs like Creative Labs, etc that you can only get at the authors site.
It has been so long I could be wrong but I though patches and new drivers also showed up in the scan?
I found that these Free Driver scans are only good if you pay your money! If I manually search for the new driver listed it is not at the authors site, or not needed, if the authors site has an online update scan.
There are a few beta programs listed that I will download like Defraggler, but most I just sit and wait for the non beta release.
