You can use DPInst (Driver Package Installer) to install driver files for your device on Windows Operating Systems. DPInst.exe is part of DIFx (Driver Install Framework tools) which comes along with the Windows Driver Kit (WDK). You can find DPInst redistributable inside the redist\DIFx\DPInst folder of the WDK.

How to ?
1. Copy dpinst.exe to the folder where the driver files (sys, inf, dll) reside.
2. Optionally create a dpinst.xml file which is used to configure dpinst (http://msdn.microsoft.com/en-us/library/ff550803(VS.85).aspx)
If your drivers are not signed you must use the <legacyMode/> tag in dpinst.xml.
3. Run dpinst.exe to install drivers using a 'device driver update' wizard.
