If you reinstall Windows Operating System, or like to try new hardware products, you may meet drivers and system Device Manager more often. It was unable to do as much as you would like to with Windows Built-in utilities. Imagine the occasions: How to identify unknown hardware devices? How to batch disable some of them? How to backup the drivers of them when driver installation media is lost? …
In this post, you can learn the knowledge and skills to device identification, as well as driver management and troubleshooting.
- Identify Unknown Devices
You have reinstalled Windows 7 for your friend, when you almost done all the things, you found some yellow question or exclamatory mark in Windows Device Manager…
It may be the incorrect driver information that caused the problem, in order to find the right answer for downloading a new and correct one, you can use Unknown Device Identifier, a tiny tool to help you identify the device model and find drivers.

- Manage your system drivers
The situation mentioned above is so disappointing, and you certainly don’t want such things to occur again. The best way to prevent the disaster is to backup all the drivers provided by hardware vendor, along the same line as System Backup.
Moreover, updating the drivers is also important. The newer version of drivers may fix bugs and compatibility problems, as well as improve performance for the device. You may want system to automatic do it for you, but Windows Update has limited capability of drivers updating.
Software recommended here is Driver Genius Professional Edition, it can: Detect and quickly backup drivers installed on your system. Automatically restore all your backed up drivers with single click. Automatically update drivers without any compatibility worries. Find the drivers that are no longer in use and quickly uninstall them.
Driver Genius Professional Edition
All that means totally manage your system drivers, safely and conveniently.
Well, you may tell me that you don’t want to pay for such kinds of software. That’s all right, because there are freeware alternatives.
Driver Magician Lite is freeware, it identifies all the hardware in the system, extracts their associated drivers from the hard disk and backs them up to a location of your choice. But you must restore them via Driver tab in Windows Device Manager. If you want the auto restoration functions, try Device Driver Backup.

Device Doctor is a freeware Windows application that scans your computer hardware and checks to see if there are new driver updates available for your devices. It also locates drivers for “unidentified devices” in the Windows Device Manager.

Do you think thus enough yet? But it’s not the end.
- Troubleshoot your drivers and system services
Hardware drivers and Windows system services are inseparable, so I recommend two tiny tools here to help you troubleshoot them.
DevManView is an alternative to the standard Device Manager of Windows, which displays all devices and their properties in flat table, instead of tree viewer. You can batch enable or disable the devices, and to export the detailed information selectively.

ServiWin is another Nirsoft product, it allows you to easily stop, start, restart, pause, and continue service or driver, change the startup type of service or driver (automatic, manual, disabled, boot or system), save the list of services and drivers to file, or view HTML report of installed services/drivers in your default browser. The Offline Mode allows you to connect another instance of Windows operating system.
In the last paragraph, I offer you another Windows Device Manager Replacement, Device Remover. Hope you can like it
