[C++] Detect Windows Build?

Question

I have some code that depends on APIs that have changed from Windows 10 Build 20348 onwards. Is there a reliable way to check which build my app is running on?

Answer 1

GetVersion, GetVersionEx, VerifyVersionInfo, and the Version Helper functions are for desktop apps only. Universal Windows apps can use the AnalyticsInfo.VersionInfo property for telemetry and diagnostic logs.

In order for your app to target Windows 8.1 or later, you'll need to include an app (executable) manifest for the app's executable.

Hi, @ravi jagannadhan
The RtlGetVersion routine returns version information about the currently running operating system. You could try the snippet below.

 #include <iostream>  
 #include<Windows.h>  
  
typedef LONG NTSTATUS, * PNTSTATUS;  
#define STATUS_SUCCESS (0x00000000)  
  
typedef NTSTATUS(WINAPI* RtlGetVersionPtr)(PRTL_OSVERSIONINFOW);  
  
RTL_OSVERSIONINFOW GetRealOSVersion() {  
    HMODULE hMod = ::GetModuleHandleW(L"ntdll.dll");  
    if (hMod) {  
        RtlGetVersionPtr fxPtr = (RtlGetVersionPtr)::GetProcAddress(hMod, "RtlGetVersion");  
        if (fxPtr != nullptr) {  
            RTL_OSVERSIONINFOW rovi = { 0 };  
            rovi.dwOSVersionInfoSize = sizeof(rovi);  
            if (STATUS_SUCCESS == fxPtr(&rovi)) {  
                return rovi;  
            }  
        }  
    }  
    RTL_OSVERSIONINFOW rovi = { 0 };  
    return rovi;  
}  
int main()  
{  
    auto VN=GetRealOSVersion();  
    std::cout << VN.dwBuildNumber ;  
      
}  

Windows 10 build 18362 (also known as SDK version 1903)

The number in the picture is the build I got.
