OSVERSIONINFOW.dwBuildNumber does not return the complete build number of Windows 10


The build number of my Windows 10 is 18363.900, as shown in the below picture.

About Windows - OS Build I tried RtlGetVersion(PRTL_OSVERSIONINFOW), but OSVERSIONINFOW.dwBuildNumber only returns 18363.

Why doesn't RtlGetVersion return the complete build number? How can I get the complete OS Build number of Windows 10?


Solution

  • This version is not returned by dwBuildNumber, what you want is called UBR can be read from a DWORD from registry:

    This number shows the patchlevel. My 329 shows I have this patch installed
