DriverGuide Toolkit identifies and lists drivers installed on your computer and, when connected to the Internet, allows you to search DriverGuide.com (and other sources) for driver updates and manufacturer sites. In addition, it allows you to backup your currently installed drivers for safe keeping. Backing up your Windows driver files means that they will be available to you the next time you need to reinstall the driver or the whole operating system. DriverGuide Toolkit places the driver files in one organized location of your choosing.

DriverGuide Toolkit is especially helpful in situations where you have a computer in your possession and the internal hardware is unknown. DriverGuide Toolkit can identify the hardware on the system and the associated drivers, back them up to a specified location, and find the latest driver updates for them. DriverGude Toolkit is even network compatible - you can just as easily connect to a remote computer on your network, backup drivers, and find updates!

As a thanks to our members we are now distributing this as shareware with many valuable features that are yours for free, regardless of whether you decide to buy a copy! So give it a try, we're sure you'll use it again and again.

You realize that formatting a computer doesn't remove all viruses. They store in your memory and bios until you reinstall them come out again. Remove them properly then if you still need to reinstall the OS you can do so safely. Download the drivers you need online.

ask sony company
hot-line

you will need to go to the manufacturer's website. it helps to know the exact hardware you have at all times.

Otherwise you might have to physically remove each hardware device and look for its serial or model number. What a fun chore

u can download them from their official sites
