SlimDrivers

This tool tried to install an older version of a driver.
Didn't find a download limitation, like my previous favourite Drivermax. Hope they keep up this good work.
For automatic driver updates (all at once), you can upgrade to premium, but it isn't necessary.

DriverEasy detected more drivers than SlimDrivers. So I prefer DriverEasy about SlimDrivers. After Slimdrivers had updated all drivers on Vista Business 64bit und reported all drivers to be actual and OK, there remained an "Other USB-device" not working and yellow-marked:

After "optimizing" all drivers with SlimDrivers DriverEasy reported 2 missing and 23 outdated drivers.

My Hauppauge WinTV USB Card "Hauppauge WinTV HVR-900H 64bit (66xxx)" did not work with the drivers from SlimDrivers, because the drivers for this USB 3.0-Card could not be installed:

• Renesas Electronics USB 3.0 Host Controller
• Renesas Electronics USB 3.0 Root Hub

Only with the DriverEasy-Updates I could use the "Hauppauge WinTV HVR-900H 64bit (66xxx)" which has the drivers Renesas Electronics USB 3.0 Card as a precondition.

Otherwise DriverEasy wanted to install the V7-drivers for "Hauppauge WinTV HVR-900H 64bit (66xxx)"-USB-device, without asking. I wanted to keep the V6-version, because VTPlus does not work with WinTV V7. In this point SlimDrivers had the better behaviour.

I think that this program's crowdsourced data should mean that it will eventually outperform all other options. However, at the moment, the program often recommends wrong drivers when I use it.

With IOBit Driver Booster I have much more frequently updated drivers in comparison with this one.
Negative opinion.

I have tried a ton of programs for opdating drivers, and this one is fine, but not great.
I prefer using IObit Driver Booster, it is much better at detecting drivers in need of an update.
