More options for third party software updates

Not long ago I mentioned the Secunia PSI (Personal Software Inspector) as a mean to update your third party software on Windows.

Now I noticed that SANS ISC has a nice article with some more recommendations:

Other options are UpdateStar (Windows), SUMo - Software Update Monitor (Windows), VersionTracker [Pro] (Mac and Windows), RadarSync (Windows), UDC - UpdateChecker (Windows), Belarc Advisor (Windows), and App Update Widget (Mac).

I have not tried any of them yet :-)

The same day they had a really good point, about something that often bothers me on Windows and Mac:

Unprivileged user vs. Administrator: A few third-party Windows software do not show the availability of new updates unless you are running as Administrator.
...
Therefore, the conclusion is that you need to periodically (every day?) login as (or run things as) Administrator to perform periodic tests for new updates. Obviously, this is not practical for end users, so we clearly need to improve the third-party update mechanisms in Windows to be accurate, up-to-date and work smoothly from non-privileged accounts.
