Get service pack name from a driver?

Hi,

From within a driver, I want to get the string name of the service pack, e.g.
"Service Pack 1, v.1247"

The function PsGetVersion() is supposed to do the trick, but I can't get a
string out of it, neither from within DriverEntry, nor any other point in my
driver. (I do get other version info from PsGetVersion() though, but not the
SP name.)

Is there any other way to get the service pack name string from within a
driver?


Thanks,

/ Hannes.

Greetings,

The best method, via the kernel, is to use the RTL_OSVERSIONINFOEXW via
RtlGetVersion() and RtlVerifyVersionInfo() found in the DDK.
With this method you can obtain the Major and Minor version of the
installed service pack, among other information.
These are defined in NTDDK.H

Hope this helps.

Greetings,

Yes, there is another way. You can read the registry key at:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

Look for CDSVersion. You will find a bunch of other stuff there too.
PsGetVersion() only works during system initialization and the DDK
points to this key as an alternative.

Thanks

CSDVersion. It contains the string name of the service pack.

That does not return a string, it returns an enum. I need a string...

Is RtlGetVersion accessible in Windows 2000 ? I need to run this on both
Windows 2000 and on Windows XP (and above).

ntoskrnl.lib for XP has it, but not for 2000. For 2000, it exists in
ntdll.lib, but that's usermode stuff that I'd better not use from my driver,
I guess.

So, for Windows 2000, it seems the only way to get the service pack name is
to open up the registry.


Can anyone help me figure out why PsGetVersion() does not return the service
pack string? It is documented to do so, but for me it does not - not even
when called from my DriverEntry().


Thanks,

/ Hannes.

A string? Fine! This is CSDVersion registry value.

Greetings,

I've been debugging PsGetVersion in order to determine why it does not
return the ServicePack string. As it turns out, the function does indeed
copy the string, but the string is always NULL. Windows itself does not
use this function to obtain the service pack string, but rather uses the
registry only.
The only remaining functionality of the function is to obtain the major,
minor, and build values. The string is a stump.

My educated guess is that this functionality is a carry over from some
previous release and now remains empty.

I hope this helps.

Thanks

Thanks for sharing that. At least I know I'm not doing anything wrong.

I'll just go ahead and get it from the registry, then!
