How to Save Current Drivers before Updating?

Double Driver is exactly what you are looking for.

However, the download link on the authors webpage does not seem to work. I found this version over at Major Geeks

http://www.majorgeeks.com/files/details/double_driver.html

Download and run the application. By default, the program will auto select all of the drivers you need to have your computer function properly.

When the application opens, click Backup > Scan Current System to scan your system for drivers. After Double Drivers scans your system, click Backup Now and select a location to save your drivers to. I would recommend putting them on a thumb drive or something if you are planning on reinstalling your operating system, otherwise you will end up erasing them when you go to format your hard drive (if you plan on doing a full reinstall of windows).
