SUMMARY

This article describes the how to configure Windows 2000 to permit users who do not have administrator or power user permissions to install and uninstall device drivers in Windows 2000.


MORE INFORMATION

Non-administrative level users require no additional permissions to install or uninstall device drivers if the device is supported hardware with a Plug and Play device ID to driver match. If you provide a properly-signed OEM driver package when using the "New Hardware Found" wizard in the case of either no match or a compatible-rank match, that signed .inf file and it's related files are now present on your computer. Because of this, any subsequent "new hardware" of the same type (such as hardware-rank match in the same .inf file and using the same files) is automatically installed by Plug and Play manager without further user interaction required.

NOTE: Often devices appear as "new" to Plug and Play when they don't supply serial numbers, and so rely on location to uniquely identify themselves (such as plugging the same mouse into two different ports on a USB hub appear to use as two different mice).

You can also update drivers for a specific computer by using a specific user. At a command prompt, type runas /u:machine\administrator mmc.exe devmgmt.msc, and then press ENTER where machine is your computer name. The "runas" command permits you to run anything as the specified user, provided you have the correct password. Note that this only permits you to upgrade drivers. When a new device is found that is running in a separate process and it does not come with hardware-rank matches, it does not work because that process does not have the correct privileges. Hardware that we support "out of the box" with compatible-rank matches meaning there is more then one hardware device that uses the same device driver in the box always requires (administrative privileges) user confirmation/interaction to install. However the user can supply an OEM driver disk with a hardware-rank match signed driver package and not require administrative privileges.
