No, OpenScManager and CreateService work for legacy drivers, but a WDM
driver is plug and play. You need to look at the DevCon source in the DDK
to see how to load a PNP driver.

You can also take a look at the DIFx API for installing drivers. The DIFx
API is part of the DIFx set of tools and is available in the WDK. You can
also download it from -

Does legacy driver support given in VISTA? Do we need to port all the
legacy drivers for VISTA ? or we can still use the same way i.e.
OpenSCManager and create service in VISTA?

No driver models have been removed in Vista. In fact, no driver model
has ever been removed in the history of Windows.

You can still run legacy drivers on Vista. You cannot install WDM/PnP
drivers using the SCM though. This requirement is not new, you were
never able to use the SCM to install a WDM/PnP driver.

Four words: Kernel mode printer drivers (deprecated in Win2K, no longer logo’d in XP, and unloadable in Vista- by design).

I stand corrected. Kernel printer drivers have a fascinating circular
history:
NT 3: Not possible
NT 4: Required
2000: Deprecated
XP: Not logo’d
Vista: Not possible

In general, all Windows NT-based OS versions support “legacy” NT device
drivers.
However, not all pre-Vista kernel-mode APIs are supported on Vista.
The first thing that you should do is see if your driver can be built under
the Vista build environment. If it can be built under Vista build
environment, then you are probably in good shape.
Good luck,

I woulnd’t go that far. I think it’s safe to say that VXD support is
gone post Windows ME. (That is a A Good Thing!)

Not quite 
Consider the massive changes the video driver architectures throughout the history of Windows… continuing to this day with the LHDDM.
Another example of a dead driver architecture: To the best of my knowledge you can no longer write NDIS full MAC drivers (those having been replaced by NDIS Miniports).

VXDs were never supported on the NT based OS’s so I don’t know if it can
count as a driver model which is no longer supported…

Well, that’s a semantics issue. In the line of 16-bit systems, starting
with Windows 386 and ending with Windows Me, no driver model was ever
removed. In the line of 32-bit systems, starting with Windows NT 3.1
and continuing through Vista, no driver model was ever removed (although
some driver models migrated from user to kernel and back). The VxD
model was not really “removed”, it just faded away because there was no
follow-on to Windows Me.
The VxD world is a fascinating one. It is essentially an entirely
separate operating system, for which Windows just happens to be one of
the tasks. VxDs were fun to write.
One of my favorite anto-Microsoft images was the one from 1999 or so
that pointed out that Microsoft’s Windows offerings were CE, ME, and
NT: Windows CEMENT, thick as a brick.

I disagree. Although the model migrated from user mode to kernel mode
a decade ago, a driver writer who had been comfortable writing Windows
NT 3.1 display drivers would have no trouble at all maintaining an XP
display driver. There are a few new entry points, and you have the
addition of D3D, but the MODEL hasn’t changed. You still have a display
driver with entry points like DrvEnablePDEV and DrvBitBlt, and a
miniport handling ioctls for the hardware access.
I will concede that LDDM is an entirely new beast, but old-style display
drivers still work. The old model has not been removed. Yet.
Another example of a dead driver architecture: To the best of my knowledge you can no longer write NDIS full MAC drivers (those having been replaced by NDIS Miniports).
I don’t know NDIS well enough to come up with a ego-deflating witty
response…
