Efficient Method to Update Sony Drivers

There are a number of frequent alerts and also other messages which you may get in the driver updating process, a number of which I've paraphrased and listed here together with guidance on what to do:

There are numerous of common alerts and other messages that you might get in the driver updating procedure, several of which I've paraphrased and listed here as well as guidance on what you can do:

Windows cannot verify that the driver is compatible: Touch or click Yes to continue installing it if you're sure this driver is the right one. Choose No if you think you might have the driver for the wrong model or something like that, in which case you should look for other INF files or maybe an entirely different driver download.

Windows can't verify the publisher of this driver software: Choose Yes to continue installing this driver only if you received it directly from the manufacturer or from their installation disc. If you downloaded the driver elsewhere and didn't exhaust your search for a manufacturer-provided one, choose No.

This driver hasn't been signed: Similarly for the creator verification problem earlier mentioned, pick Yes only when you're comfortable about the driver's supply.

Windows requires a digitally signed driver: You won't even see the above two messages because Windows won't let you install a driver that has a digital signature issue, in 64-bit versions of Windows. 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.
