OS Info for Windows 8 and 10

[sinsi]

Dave, this might be of use - Targeting your application for Windows

In Windows 8.1 and Windows 10, the GetVersion and GetVersionEx APIs have been deprecated and superseded by the Version Helper APIs. While you can still call the deprecated APIs, if your application does not specifically target Windows 8.1 or Windows 10, you will get Windows 8 version (6.2.0.0).

In order to target Windows 8.1 or Windows 10, you need to include the app manifest in the source file.

jj, you can still build exes for 2000 because the version helpers use APIs that 2000 has.
Attached is the header from the Win10 SDK.

The version helper can be very useful with a lib who include it's functions.

jj2007's GetVersionInfo, posted above, agrees, so apparently 8.1 = 6.3! Microsoft needs to hire better arithmeticians

The Major and minor version must be read with the help of:
https://msdn.microsoft.com/fr-fr/library/windows/desktop/ms724833(v=vs.85).aspx
6.3 = Windows 8 or Windows Server 2012 R2

I try to made that without any modify on the answer of GetVersionInfoEx

I have added that to my rc file

#define _NT_TARGET_VERSION $(_NT_TARGET_VERSION_LATEST)
#define IDR_VERSION1 1
#define SXS_MANIFEST_RESOURCE_ID  1
#define SXS_MANIFEST "cpusys.manifest"
#define SXS_ASSEMBLY_NAME "Microsoft.Windows.Foo"
#define SXS_ASSEMBLY_VERSION 1.0   
#define SXS_ASSEMBLY_LANGUAGE_INDEPENDENT 1
#define SXS_MANIFEST_IN_RESOURCES 1

cpusys.manifest is the same as the html page

Yes, it uses VerifyVersionInfoW, which in turn calls good ol' RtlGetVersion, the one I used in my code. Thanks for the header file, I had seen an unofficial one somewhere, good to have the original.

While you can still call the deprecated APIs, if your application does not specifically target Windows 8.1 or Windows 10, you will get Windows 8 version (6.2.0.0).

RtlGetVersion returns 6.3 on Windows 8.1, without manifest. The logic "manifest-wise my application is not specifically targeted for 8.1, so I want the OS to fake an 8.0" is rather redmondish

Here a test prog

i find an inversion on:
Windows  OSVERSIONINFOEX.wProductType == VER_NT_WORKSTATION

To view Windows 10 in the zip,OSVERSIONINFOEX.wProductType != VER_NT_WORKSTATION

Perhaps is there the same problem with other system ??

Seems to work OK on my Win7 64. The "Windows Server 2008 R2" is about of the same vintage which may account for the mis identification.

Hutch,
What do you get from a simple commandline ver?

i guess that would formatted as "5.1.2600 SP 3.0"

Code Select Expand

RtlGetVersion   5.1 SP 3.0 build 2600
Suite mask      0100: SINGLEUSERTS
ProductType     WORKSTATION
CSDVersion      Service Pack 3

@Dave: Thanks :icon14: So far RtlGetVersion returns correct numbers for all OS versions, including Sinsi's 10.0. It seems to be the lowest level solution, except for reading the PEB directly.

Too bad,there is not real change that justify this.The code worked perfectly in my old xp.
It is 32 bit,it's not so easy to change from 32 to 64 in asm.

[jj2007]

It is 32-bit indeed, just launch it with Olly. It displays a RichEd control with the text below.

@Yves: The cpu is OK but I'm definitely not running Windows Server 2008 R2 8)

After some test,Rtlgetversion seems to be a not very good way.
Just answer 0 as wProductType.
The god (MSDN) way is this one:

To obtain the full version number for the operating system,
call the GetFileVersionInfo function on one of the system DLLs,
such as Kernel32.dll, then call VerQueryValue to obtain
the \\StringFileInfo\\<lang><codepage>\\ProductVersion subblock of the file
version information.

[adeyblue]

Don't forget

void
__stdcall
RtlGetNtVersionNumbers(
   ULONG* pMajor,
   ULONG* pMinor,
   ULONG* pBuild
);

from XP onwards because 14 methods that return the version just wasn't enough.

[TouEnMasm]

Only 14 methods ??????:
If it is a game , the more powerfull is dumpbin
He found "RtlGetNtProductType"
After an acces violation,RtlGetNtProductType PROTO product:LPDWORD
He return 1 (WORKSTATION on Windows 10)
I will try to fulfill others conditions.

@Yves: Which test? Show me one example where RtlGetVersion doesn't return the correct OS version number.

@adeyblue: Nice find :t And it looks really, really foolproof :icon_mrgreen:
