C# - How to show the full Windows 10 build number?

问题

How to show the full Windows 10 build on C#?

I'm currently using Environment.OSVersion.VersionString but it's not showing the full build number

The result:

Microsoft Windows NT 10.0.17134.0

But I want the last number, my full build: 10.0.17134.228

I want to know how can I show the last missing number. Not only where to find the number. The c# code to get it.

回答1:

The Windows 10 build number is stored in the registry in HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\ in the UBR key.

Here's how to get it in code:

using Microsoft.Win32;

// ...

RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion");

var buildNumber = registryKey.GetValue("UBR").ToString();

EDIT: Fixed the value name to get the correct number for OP. Credit for the correct key to Jorge Aguiar.

You can get the last missing number at

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\UBR

(it's a DWORD value. It might be missing in some Windows versions.)

回答3:

You've to combine the 2 values to get "OS build":

RegistryKey registryKey = Registry.LocalMachine.OpenSubKey(@"SOFTWARE\Microsoft\Windows NT\CurrentVersion");

var _UBR = registryKey.GetValue("UBR").ToString();
var _CurrentBuild = registryKey.GetValue("CurrentBuild").ToString();

string _version = _CurrentBuild+"."+ _UBR;
