I recently found your driver update program and decided to give it a shot, since it is receiving very good reviews and I'm not entirely pleased with my paid subscription to DriverMax Pro.
The issue is the differences between the two products' findings (I have attached a screen shot).
SlimDrive only shows 1 driver requiring updating while DriverMax lists 15.
My system is a Gateway 550GR, WinXP SP3, Home edition.
I also see this same inconsistency on my old Dell laptop running WinXP Pro, SP3.
Are these additional driver being identified by SlimDriver somewhere else? Am I missing something due to lack of familiarity with you product?
