C# Determine OS Version in .NET 6

What is the correct way to determine the correct OS version in .NET 6?
I found many different solutions regarding this topic. All of them are quite out of date I think.
I want to get something like "Windows 10 Enterprise build 22000 (64 bit)"
Environment.OSVersion.ToString()
gives "Microsoft Windows NT 10.0.22000.0"
RuntimeInformation.OSDescription
gives "Microsoft Windows 10.0.22000.0"
RuntimeInformation.OSArchitecture.ToString()
gives "X64"
So far I'm using:
Console.WriteLine(RuntimeInformation.OSDescription + " | " + RuntimeInformation.OSArchitecture.ToString())
This gives "Microsoft Windows 10.0.22000.0 | X64"
Is there a way to get something like "Windows 10 Enterprise | X64" in .NET 6?
In addition to that, I'm looking for a way to get the Windows install language and the current language.

The function:
RuntimeInformation.OSArchitecture.ToString();
returns the architecture that the OS was compiled, that is, in this case it was x86-64 (string-shaped)
The functions:
Environment.OSVersion.ToString()
RuntimeInformation.OSDescription
returns windows version
With this and with this link here:
(Get OS Version / Friendly Name in C#) we can get to this code:
using System.Runtime.InteropServices;
using System.Management;
static int GetARCHFriendlyBits(Architecture architecture)
{
return architecture switch
{
Architecture.X64 => 64,
Architecture.X86 => 32,
Architecture.Arm64 => 64,
Architecture.Arm => 32,
Architecture.Wasm => -1,
Architecture.S390x => -1,
_ => -1,
};
}
static string GetOSFriendlyName1()
{
string result = string.Empty;
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
ManagementObjectSearcher searcher = new("SELECT Caption FROM Win32_OperatingSystem");
ManagementObject os = searcher.Get().Cast<ManagementObject>().First();
if (os["Caption"].ToString() is string osResult)
result = osResult;
}
else
{
return $"{RuntimeInformation.OSDescription} ({RuntimeInformation.OSArchitecture})";
}
if (result == string.Empty)
return $"{RuntimeInformation.OSDescription} ({RuntimeInformation.OSArchitecture})";
else
return $"{result} build {Environment.OSVersion.Version.Build} ({GetARCHFriendlyBits(RuntimeInformation.OSArchitecture)} bits)";
}
static string GetOSFriendlyName2()
{
string result = string.Empty;
if (RuntimeInformation.IsOSPlatform(OSPlatform.Windows))
{
ManagementObjectSearcher searcher = new("SELECT Caption FROM Win32_OperatingSystem");
ManagementObject os = searcher.Get().Cast<ManagementObject>().First();
if (os["Caption"].ToString() is string osResult)
result = osResult;
}
else
{
return $"{RuntimeInformation.OSDescription} ({RuntimeInformation.OSArchitecture})";
}
if (result == string.Empty)
return $"{RuntimeInformation.OSDescription} ({RuntimeInformation.OSArchitecture})";
else
return $"{result} | {RuntimeInformation.OSArchitecture}";
}
Console.WriteLine(GetOSFriendlyName1());
Console.WriteLine(GetOSFriendlyName2());
which in my case writes this line here on the console:
Microsoft Windows 11 Home Single Language build 22621 (64 bits)
Microsoft Windows 11 Home Single Language | X64
To use System.Management, I had to install microsoft NuGet System.Management

C# Windows how ro run exe after detect .Net version

I Have a Three EXE's
EXE1 build with 3.5 net framework
EXE2 build with 4.5 net framework
EXE3 build with 4.6 net framework
I want to run exe after detect which.Net version already installed and according to that start exe
if 3.5 installed
RUN(EXE1)
if 4.5 installed
RUN(EXE2)
if 4.6 installed
RUN(EXE3)
i think about wix setup, iexpress but didnt get any thing so how can we do this ?
or its is possible? if yes then how and if no then so can we do this with the help of third party software?
so I need a way to run exe as per platform because each platform has
their own .Net framework

there is 2 way: using bath file to detect .net version after that run exe for this version
or build a porogram exe depend .net 2 after that this exe decide witch file must run
Update:
this samples give you version of .net freamwork are inistaled
for.net 4 and older

Update2:
by this Update you get latest version of .net at batch File
#echo off
setlocal

if "%%i"=="Version" (
SET .NetVer=%%k
)
)
#for /F "tokens=1,2*" %%i in ('reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full" /v "Version"') DO (
if "%%i"=="Version" (
SET .NetVer=%%k
)
)
ECHO The most current version of Net in use is %.NetVer%
and by this code you can run program but dont forget the bat file must be in folder the exe files are there
start myProgram.exe
exit

If you use Windows Installer (such as through wix), you can use the MsiNetAssemblySupport property to condition a custom action that launches your executable. If you use wix specifically, the WixNetfxExtension can be asked to set other properties that may be easier to use. Here is wix's list of .NET properties.
However I suspect this is the wrong approach. It should be much easier to write a single .NET executable that targets the lowest framework version you support, and include a .config file1 with a supportedRuntime element that enables it to run on a wider spread of frameworks. (See How to: Configure an App to Support .NET Framework 4 or 4.5.
Also, depending on what the executable does, you may be better off writing a C++ executable, a C++ DLL (so it can interact with Windows Installer), or even leveraging native Windows Installer functionality instead of custom actions. (If applicable, the last option is ideal.)
1Note that Windows Installer EXE custom action support for temporary files will only extract a single file to the temp folder, so your .config file would not be found in these configurations. Alternate approaches would be required; various Windows Installer tools have their own approaches for mitigating this problem.

Check Windows name c#

I will check my Windows os name (Windows 8 Pro) in c# but it gives an error, what's wrong?
RegistryKey reg = Registry.LocalMachine.OpenSubKey(#"HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion", true);
string currentKey;
currentKey = reg.GetValue("ProductName", true).ToString();
textBox1.Text = currentKey;

You can use Environment.OSVersion for this.
Edit:
Getting the OS name is answered here: Stackoverflow OS Friendly name

I'll just quote MSDN:
Registry.GetValue()-Method
Retrieves the value associated with the specified name, in the specified registry key. If the name is not found in the specified key, returns a default value that you provide, or a null reference (Nothing in Visual Basic) if the specified key does not exist.
This means that the value you are trying to get is not available.
Edit possible Solution:
Source: How to get the “friendly” OS Version Name?
private string GetOSName()
{
var name = (from x in new ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem").Get().OfType<ManagementObject>()
select x.GetPropertyValue("Caption")).First();
return name != null ? name.ToString() : "Unknown";
}
And to check whether OS is 32 or 64bit use following code:
private string GetOSBitness()
{
if (Environment.Is64BitOperatingSystem == true)
return " x64";
else
return " x86";
}
Above code will return (at least on my system):
Microsoft Windows 7 Professional x64

You can get the commercial name of your operating system, including service pack information by querying the Windows Management Instrumentation interface:
public static string GetOSNameAndVersion()
{
string str = Environment.OSVersion.ToString();
try
{
var obj2 = new System.Management.ManagementObjectSearcher("SELECT * FROM Win32_OperatingSystem")
.Get()
.Cast<System.Management.ManagementObject>()
.First<System.Management.ManagementObject>();
str = ((string)obj2["Caption"]).Trim();
string spMaj = obj2["ServicePackMajorVersion"].ToString();
string spMin = obj2["ServicePackMinorVersion"].ToString();
string osVer = obj2["Version"].ToString();
if (((spMaj != "") && (spMaj != "0")) || ((spMin != "") && (spMin != "0")))
{
str = str + " SP " + spMaj;
if ((spMin != "") && (spMin != "0"))
{
str = str + "." + spMin;
}
}
if (Environment.Is64BitOperatingSystem)
{
str = str + " x64";
}
else
{
str = str + " x86";
}
str = str + " (" + osVer + ")";
}
catch
{
// TODO: Implement your own exception handling here
// the way it is, the method will fall back on to the Environment.OSVersion
// if the query fails
}
if (str.StartsWith("Microsoft"))
{
str = str.Substring("Microsoft".Length + 1);
}
return str;
}

Hacking at the registry is probably the wrong solution.
But why is it failing? Since you use Registry.LocalMachine, the HKLM is wrong. Remove the HKLM. That's a clear error.
On top of that watch out for registry redirection. Perhaps your process is 32 bit but the value you are looking for is in the 64 bit view of the registry. Use the RegistryView enumeration to gain access to the 64 bit view.

Your program is subject to what I presume to be a NullReferenceException because the program cannot find the registry sub-key because the path that you have supplied is incorrect.
You do not need to specify the hive in the hive path because your relative path is already the local hive. Exclude the hive from the path like like this:
Registry.LocalMachine.OpenSubKey(
#"SOFTWARE\Microsoft\Windows NT\CurrentVersion", true);
Depending on your programs' access privileges and operating system configuration your program may still throw an exception due to your program having insufficient access permissions.

availability of Win32_MountPoint and Win32_Volume on Windows XP?

From the MSDN articles I've found -- http://msdn.microsoft.com/en-us/library/aa394515(v=VS.85).aspx -- Win32_Volume and Win32_MountPoint aren't available on Windows XP.
However, I'm developing a C# app on Windows XP (64bit), and I can get to those WMI classes just fine. Users of my app will be on Windows XP sp2 with .Net 3.5 sp1.
Googling around, I can't determine whether I can count on this or not.
Am I successful on my system because of one or more of the following:
- windows xp service pack 2?
- visual studio 2008 sp1 was installed?
- .Net 3.5 sp1?
Should I use something other than WMI to get at the volume/mountpoint info?
Below is sample code that's working...
public static Dictionary<string, NameValueCollection> GetAllVolumeDeviceIDs()
{
Dictionary<string, NameValueCollection> ret = new Dictionary<string, NameValueCollection>();
// retrieve information from Win32_Volume
try
{
using (ManagementClass volClass = new ManagementClass("Win32_Volume"))
{
using (ManagementObjectCollection mocVols = volClass.GetInstances())
{
// iterate over every volume
foreach (ManagementObject moVol in mocVols)
{
// get the volume's device ID (will be key into our dictionary)
string devId = moVol.GetPropertyValue("DeviceID").ToString();
ret.Add(devId, new NameValueCollection());
//Console.WriteLine("Vol: {0}", devId);
// for each non-null property on the Volume, add it to our NameValueCollection
foreach (PropertyData p in moVol.Properties)
{
if (p.Value == null)
continue;
ret[devId].Add(p.Name, p.Value.ToString());
//Console.WriteLine("\t{0}: {1}", p.Name, p.Value);
}
// find the mountpoints of this volume
using (ManagementObjectCollection mocMPs = moVol.GetRelationships("Win32_MountPoint"))
{
foreach (ManagementObject moMP in mocMPs)
{
// only care about adding directory
// Directory prop will be something like "Win32_Directory.Name=\"C:\\\\\""
string dir = moMP["Directory"].ToString();
// find opening/closing quotes in order to get the substring we want
int first = dir.IndexOf('"') + 1;
int last = dir.LastIndexOf('"');
string dirSubstr = dir.Substring(first , last - first);
// use GetFullPath to normalize/unescape any extra backslashes
string fullpath = Path.GetFullPath(dirSubstr);
ret[devId].Add(MOUNTPOINT_DIRS_KEY, fullpath);
}
}
}
}
}
}
catch (Exception ex)
{
Console.WriteLine("Problem retrieving Volume information from WMI. {0} - \n{1}",ex.Message,ex.StackTrace);
return ret;
}
return ret;
}

I guess the Win32_MountPoint and Win32_Volume classes are available on Windows XP Professional x64 Edition because it's based on the Windows Server 2003 codebase. On 32-bit versions of Windows XP, these classes don't exist and to perform your task you need to P/Invoke native volume management functions, like Tim said.

You may need to pinvoke into the Win32 Volume Management Functions

check whether microsoft components are present or not

I want to check whether certain microsoft components like wmencoder, directx or wmplayer
are installed or not. If it is installed, can I also get its version number?
How can I do that?
Thanks in advance.

I use the below to determine if other applications are installed, however you will need to know the "unique" product code (from the setup project in Visual Studio) that the application is installed with in the registry.
Include
using System.Diagnostics;
using Microsoft.Win32;
Usage:
// HKEY_LOCAL_MACHINE\SOFTWARE\Classes\CLSID\{0006F03A-0000-0000-C000-000000000046} << This is outlook 2003
String retval = "";
// Look to see if Outlook 2003 is installed and if it is...
if ((checkComServerExists("{0006F03A-0000-0000-C000-000000000046}", out retval)))
{
// Update boolean flag if we get this far so we don't have to check again
Console.WriteLine("Office CSLID exists - Version: " + retval);
}
Function:
// Checks to see if the given CLSID is registerd and exists on the system
private static Boolean checkComServerExists(String CLSID, out String retval)
{
RegistryKey myRegKey = Registry.LocalMachine;
Object val;
try
{
// get the pathname to the COM server DLL/EXE if the key exists
myRegKey = myRegKey.OpenSubKey("SOFTWARE\\Classes\\CLSID\\" + CLSID + "\\LocalServer32");
val = myRegKey.GetValue(null); // the null gets default
}
catch
{
retval = "CLSID not registered";
return false;
}
FileVersionInfo myFileVersionInfo = null;
try
{
// parse out the version number embedded in the resource
// in the DLL
myFileVersionInfo = FileVersionInfo.GetVersionInfo(val.ToString());
}
catch
{
retval = String.Format("DLL {0} not found", val.ToString());
return false;
}
retval = myFileVersionInfo.FileVersion;
return true;
}

My first thought would be WMI. Class Win32_SoftwareElement (on MSDN)
But likely to take some work to get the right classes and queries. Start with the WMI tools for WMI CIM Studio.
Using PowerShell, something like:
gwmi win32_softwareelement -filter "name like '%play%'" | ft
will allow finding the right ids. (Warning: this is extremely slow.)
Possible that the MS Installer (MSI) API has something quicker.

I use RegShot to determine registry setting that can be used to check if a softwre is installed ..

Here is also a small code snippet that uses, among others, Type.GetTypeFromProgID and registry access.
