Windows 2008
%systemroot%\System32\drivers
%systemroot%\System32\driverStore
By default, membership in the Administrators group, or equivalent, is the minimum required to install a device driver package in the driver store.
The
installation of Windows 2008 server and its service packs include a library of
device drivers. A standard user on the computer can install a device without
needing elevated user permissions if a compatible device driver can be found
from the DriverStore.
OEM drivers are not included in the base Windows 2008 and its service packs.
A standard user can install an OEM driver package only if the following conditions are met:
· The device driver package is signed with a valid digital certificate.
· The device setup class for the driver is in the computer policy Allow limited users to install drivers for these device classes.
There is no device driver package in DriverStore for this unknown device.
Stage a Device Driver in the Driver
Store
Download the driver from ASUS site and expand it to C:\ drive.
C:\>pnputil -a c:\WINVISTA/asacpi.inf
Microsoft
PnP Utility
Processing inf : AsAcpi.inf

You will find that the drivestore has a new folder as shown:
C:\>dir
%systemroot%\system32\driver\asacpi.sys
The system cannot find the file specified.
Because the device driver has not been installed, it will not be in %systemroot%\system32\drivers folder.
This device driver is signed by Microsoft Windows Hardware Compatibility Publisher. I will log on the system as a standard user and install the device driver.
Solution:
Logon as Administrator
Open the .inf setup file and copy the ClassGUID
gpedit.msc
Computer Configuration, Administrative Templates, System, and then Driver Installation
Allow non-administrators users to install
drivers for these device classes –Enable
Add GUID to the list
Logoff Administrator and logon as standard
user: Rob Robinson
Logoff Rob Robinson and Logon as
Administrator
From devmgmt.msc console, you will find the
driver is installed in c:\Windows\System32\Drivers folder.
If the driver package is not signed by Microsoft, or is signed by a certificate that is not currently in the Trusted Publishers certificate store, the Windows Security dialog appears asking you to confirm whether the driver should be installed. Even though you publish the unsigned package into DriverStore, a standard user can still not install it.
To configure Windows to Search Additional Folders for Device Drivers
When a new device is detected, Windows checks the driver store to see if an appropriate driver package is staged there. If not, it checks several locations to find a driver package to place in the driver store.
Regedit:
HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version
DevicePath
Add additional folder paths to the setting, separating each folder path with a semi-colon. Ensure that %systemroot%\inf is one of the folders included in the value.
When I run PenTablet_511-1.exe, it installs the files under c:\Program Files (x86)\Tablet folder. I could add the C:\Program Files (x86)\Tablet to DevicePath parameter in registry. Or, I could stage the driver files in the driverstore as shown below:
pnputil -a
"c:\Program Files (x86)\Tablet"/wacmoumonitor.inf
Microsoft PnP Utility
Processing inf : wacmoumonitor.inf

How
to Add OEM Plug and Play Drivers to Windows XP
Copy OEM drivers locally, e.g.
C:\Drivers\Nic
Or,
Copy OEM drivers to a server, e.g. \\ServerName\Drivers\Nic
(where Drivers is a shared folder)
Regedit:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\DevicePath:
REG_EXPAND_SZ:%SystemRoot%\Inf
For example,
DevicePath: REG_EXPAND_SZ:%SystemRoot%\Inf;%SystemRoot%\Drivers\Nic
Or,
DevicePath: REG_EXPAND_SZ:%SystemRoot%\Inf;\\ServerName\ShareName\Drivers\Nic
XP driver
location
Setup inf
directory: %systemroot%\inf
When I run PenTablet_511-1.exe, it
automatically install the drivers in C:\Windows\System32\drivers folder. And
all the files are installed in c:\Program Files\Tablet folder. I will edit
registry for devicePath to include C:\Program Files\Tablet folder.
If the OEM-supplied drivers for the new
device are not digitally signed and a nonadministrator user logs on to the
computer after the new hardware is installed, the user cannot complete the
installation of the device until an administrator logs on to the computer.
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.
