The Best Way to Update Sony Drivers

There are a variety of frequent warnings as well as other messages that you might get in the driver upgrading process, a number of which I've paraphrased and listed right here together with tips on what to do:

Windows requires a digitally signed driver: In 64-bit versions of Windows, you won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue. If you see this message, end the driver update process and locate the correct driver from the hardware maker's website.

To set Windows to install recommended updates

To automatically get available driver updates for your hardware, set Windows to install recommended updates. You can set Windows to automatically install important and recommended updates or important updates only. Optional updates aren't downloaded or installed automatically. To get all available updates for your devices, periodically check Windows Update for optional updates.

  1. Open Windows Update by clicking the Start button. In the search box, type Update, and then, in the list of results, click Windows Update.
  2. In the left pane, click Change settings.
  3. Under Important updates, click an item in the list. You can decide which updates to automatically download and install.
  4. Under Recommended updates, select the Give me recommended updates the same way I receive important updates check box, and then click OK. If you're prompted for an administrator password or confirmation, type the password or provide confirmation. You can also allow anyone using your computer to install updates by selecting the Allow all users to install updates on this computer check box.
