This article describes 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.
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 its 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 do not
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 mouse devices).
You can also update drivers
for a specific computer by using a specific user. At a command prompt, type the
following command, where machine
is your computer
name, and then press ENTER:
runas /u:machine\administrator mmc.exe devmgmt.msc
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.
