Well, that depends on how busy you are, how many out of date drivers you have, and your budget. The scanning feature we used is part of the trial version, which you can download here. If you want to take the time and save the money, you can run all over the web and track down the drivers yourself.
For about 35 bucks (19.95 in pounds) you get the full version. Click a button and it will download all your new drivers for you. You can then click to run their installers one at a time. You still have to go through the installation process manually, and since some driver updates will require an uninstall, restart, and install, the process can be pretty lengthy. That isn’t the scanner’s fault, installing drivers just takes time.
Another problem with driver installation is having the computer restart after an uninstall and for some reason, the installer fails to reopen and complete the process. Traditionally, assuming you remembered to where you downloaded the driver (admittedly if you are reasonably organized it shouldn’t be too hard), you would have to dig it up and run it.
Opening DriverScanner and using the “Driver scan” top tab and the “Download history” left tab (see picture) is helpful in these cases. All the downloads that have been made (that you haven’t deleted) are listed, and you can click a link to open the Windows Explorer folder containing the file. You can specify where the downloads go via the “Settings” top tab.
