The Most Efficient Way to Update Sony Drivers

There are a number of typical alerts and also other messages that you could get in the driver updating procedure, a number of which I've paraphrased and listed here along with guidance on how to proceed:

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. End the driver update process and locate the correct driver from the hardware maker's website if you see this message.

To download and update the driver for SONY VPCZ21AGX/B yourself (If you are a geek)

It's best to let Windows install device drivers automatically. But if Windows can't find a driver for your SONY VPCZ21AGX/B, you can look for a driver on the manufacturer's website of SONY. Driver updates are often available in the support section of such sites.

Once you find the updated driver, follow the installation instructions on the website. Most drivers are self-installing—after you download them, just double-click the file to begin the installation, and then the driver installs itself on your computer. What you should know is that a wrong driver may cause system malfunctioning which you should be careful about. Download a professional driver updater or find a geek to help you.
