I am the statesboro computer doctor i work on many machines i always let windows updates complete first. But iobits driver booster 3 has been able to find drivers especially the graphics accelerators that windows update doesent find.
I always uninstall it and run malwarebytes for safety. So far iobit has never left malware on the machines.
Stay away from the other stuff if offers to install
And dont do the free upgrade.
Since i specialise in virus and malware removal i would be the last person to say use it if really needed to find a hard to find driver.
I would have to say in conclusion iobit seems to be trying hard to establish a good reputation and they are certainly impressing me.
