Where Driver Booster fits
Consider it only after checking Windows Update and the hardware manufacturer's support page.
Check before you choose
Create a restore point and review each proposed driver before changing a working system.
Find the right edition
Start with the destination for your device or the publisher's website. Use the current requirements and terms there to confirm the edition you need.
Compare the workflow
Identify the problem before installing a utility. File search, remote support, hardware inspection and bootable media preparation need different permissions and can affect the computer in different ways.
