Portable Driver Magician Lite is a tool that can backup the driver configuration of your computer.
Since this is a portable product, the program does not need to be installed, so your Windows registry entries remain intact. It also means that you can place Driver Magician Lite on a removable drive and run the executable file directly from there.
The user interface of the program is very standard. Once you have initiated Driver Magician Lite, it will automatically list all the installed drivers on your computer.
The ones listed in red cannot be found in the Windows installation package, so if something bad were to happen to them, you would probably have a hard time getting them back from other sources.
This is why backing up your drivers is highly recommended. Besides the description, you can view the class, version, date and provider for each driver. If you click on a driver, you can also view the device ID and device information.
After you have selected the drivers you want to create a backup for, as well as an output destination, Driver Magician Lite will create these copies in a very short amount of time, while using a low amount of system memory and moderate amount of CPU.
All in all, Portable Driver Magician Lite is a tool that offers only half of the solution (in the free version) - backing up your drivers, not also restoring them. For more options and advanced functionality, take a look at Driver Magician.
