Operating System Version

The Version API Helper functions are used to determine the version of the operating system that is currently running. For more information, see Getting the System Version.

The following table summarizes the most recent operating system version numbers.

Operating system	Version number
Windows 10	10.0*
Windows Server 2019	10.0*
Windows Server 2016	10.0*
Windows 8.1	6.3*
Windows Server 2012 R2	6.3*
Windows 8	6.2
Windows Server 2012	6.2
Windows 7	6.1
Windows Server 2008 R2	6.1
Windows Server 2008	6.0
Windows Vista	6.0
Windows Server 2003 R2	5.2
Windows Server 2003	5.2
Windows XP 64-Bit Edition	5.2
Windows XP	5.1
Windows 2000	5.0

* For applications that have been manifested for Windows 8.1 or Windows 10. Applications not manifested for Windows 8.1 or Windows 10 will return the Windows 8 OS version value (6.2). To manifest your applications for Windows 8.1 or Windows 10, refer to Targeting your application for Windows.

Identifying the current operating system is usually not the best way to determine whether a particular operating system feature is present. This is because the operating system may have had new features added in a redistributable DLL. Rather than using the Version API Helper functions to determine the operating system platform or version number, test for the presence of the feature itself.

To determine the best way to test for a feature, refer to the documentation for the feature of interest. The following list discusses some common techniques for feature detection:

• You can test for the presence of the functions associated with a feature. To test for the presence of a function in a system DLL, call the LoadLibrary function to load the DLL. Then call the GetProcAddress function to determine whether the function of interest is present in the DLL. Use the pointer returned by GetProcAddress to call the function. Note that even if the function is present, it may be a stub that just returns an error code such as ERROR_CALL_NOT_IMPLEMENTED.
• You can determine the presence of some features by using the GetSystemMetrics function. For example, you can detect multiple display monitors by calling GetSystemMetrics(SM_CMONITORS).
• There are several versions of the redistributable DLLs that implement shell and common control features. For information about determining which versions are present on the system your application is running on, see the topic Shell and Common Controls Versions.

If you must require a particular operating system, be sure to use it as a minimum supported version, rather than design the test for the one operating system. This way, your detection code will continue to work on future versions of Windows.

Note that a 32-bit application can detect whether it is running under WOW64 by calling the IsWow64Process function. It can obtain additional processor information by calling the GetNativeSystemInfo function.

If the value that corresponds to Processor starts with ia64 or AMD64, the computer is running a 64-bit version of Windows.

How to find the operating system version using JavaScript?

How can I find the OS name and OS version using JavaScript?

14 Answers 14

If you list all of window.navigator ‘s properties using

You’ll see something like this

Note that oscpu attribute gives you the Windows version. Also, you should know that:

I started to write a Script to read OS and browser version that can be tested on Fiddle. Feel free to use and extend.
Breaking Change:
Since September 2020 the new Edge gets detected. So ‘Microsoft Edge’ is the new version based on Chromium and the old Edge is now detected as ‘Microsoft Legacy Edge’!

@Ludwig ‘s solution was brilliant. A couple of fixes (which didn’t have to do with operating system, and I couldn’t place as a comment on his original posting because this is too long):

1. IE 11 no longer identifies itself as MS IE.
2. Chrome on IOS spoofs itself as Safari

JavaScript have access to the window.navigator.platform — a string representing the platform of the browser: https://developer.mozilla.org/en-US/docs/Web/API/NavigatorID/platform

Use it to extract whatever details you need (and can). Note that there are no guarantees that the client actually uses that platform since this can easily be modified in many ways.

platform.js seems like a good one file library to do this.

You can use this javascript function to check users’ OS simply

You can find the OS name and version in the navigator object, as others have answered. The standard, cross-browser place to find this information is in the navigator.userAgent property. However, user agent strings vary widely by OS and browser.

So, I created a script to encapsulate this logic and report on the most common OSes and browsers in a familiar way, like http://www.whatsmybrowser.org.

I open-sourced the script and uploaded it to github, https://github.com/keithws/browser-report. Pull requests are welcome!

I’ve created a library for parsing User Agent strings called Voodoo. But be aware that this should not be used instead of feature detection.

What Voodoo does, is that it parses the userAgent string, which is found in the Navigator object (window.navigator). It’s not all browsers that passes a reliable userAgent string, so even though it’s the normal way to do it, the userAgent can not always be trusted.

I fork @Ludwig code and remove necessity of swfobject .

I just use swfobject code for detect flash version.

I can’t comment on @Ian Ippolito answer (because I would have if I had the rep) but according to the document his comment linked, I’m fairly certain you can find the Chrome version for IOS. https://developer.chrome.com/multidevice/user-agent?hl=ja lists the UA as: Mozilla/5.0 (iPhone; CPU iPhone OS 10_3 like Mac OS X) AppleWebKit/602.1.50 (KHTML, like Gecko) CriOS/56.0.2924.75 Mobile/14E5239e Safari/602.1

So this should work:

Haven’t been able to test (otherwise I would have improved his answer) it to make sure since my iPad is at home and I’m at work, but I thought I’d put it out there.

Hey for a quick solution you can consider the following library : UAPARSER — https://www.npmjs.com/package/ua-parser-js

Detect Windows version in .net

How can I detect the Windows OS versions in .net?

What code can I use?

15 Answers 15

System.Environment.OSVersion has the information you need for distinguishing most Windows OS major releases, but not all. It consists of three components which map to the following Windows versions:

For a library that allows you to get a more complete view of the exact release of Windows that the current execution environment is running in, check out this library.

Important note: if your executable assembly manifest doesn’t explicitly state that your exe assembly is compatible with Windows 8.1 and Windows 10.0, System.Environment.OSVersion will return Windows 8 version, which is 6.2, instead of 6.3 and 10.0! Source: here.

I used this when I had to determine various Microsoft Operating System versions:

I use the ManagementObjectSearcher of namespace System.Management

Do not forget to add the reference to the Assembly System.Management.dll and put the using: using System.Management;

Result:

Like R. Bemrose suggested, if you are doing Windows 7 specific features, you should look at the Windows® API Code Pack for Microsoft® .NET Framework.

It contains a CoreHelpers class that let you determine the OS you are currently on (XP and above only, its a requirement for .NET nowaday)

It also provide multiple helper methods. For example, suppose that you want to use the jump list of Windows 7, there is a class TaskbarManager that provide a property called IsPlatformSupported and it will return true if you are on Windows 7 and above.

You can use this helper class;

Sample code is here:

This is a relatively old question but I’ve recently had to solve this problem and didn’t see my solution posted anywhere.

The easiest (and simplest way in my opinion) is to just use a pinvoke call to RtlGetVersion

Where Major and Minor version numbers in this struct correspond to the values in the table of the accepted answer.

This returns the correct Windows version number unlike the deprecated GetVersion & GetVersionEx functions from kernel32

Via Environment.OSVersion which «Gets an System.OperatingSystem object that contains the current platform identifier and version number.»

These all seem like very complicated answers for a very simple function:

Detect OS Version:

Then simply do wrap a select case around the function.

1. Add reference to Microsoft.VisualBasic .
2. Include namespace using Microsoft.VisualBasic.Devices ;
3. Use new ComputerInfo().OSFullName

The return value is «Microsoft Windows 10 Enterprise»

The above answers would give me Major version 6 on Windows 10.

The solution that I have found to work without adding extra VB libraries was following:

I wouldn’t consider this the best way to get the version, but the upside this is oneliner no extra libraries, and in my case checking if it contains «10» was good enough.

How about using a Registry to get the name.

«HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion» has a value ProductName since Windows XP.

If you are using .NET Framework 4.0 or above. You can remove the Is64BitOperatingSystem() method and use Environment.Is64BitOperatingSystem.

First solution

To make sure you get the right version with Environment.OSVersion you should add an app.manifest using Visual Studio and uncomment following supportedOS tags:

Then in your code you can use Environment.OSVersion like this:

Example

For instance in my machine ( Windows 10.0 Build 18362.476 ) result would be like this which is incorrect:

By adding app.manifest and uncomment those tags I will get the right version number:

Alternative solution

If you don’t like adding app.manifest to your project, you can use OSDescription which is available since .NET Framework 4.7.1 and .NET Core 1.0.

Note: Don’t forget to add following using statement at top of your file.

You can read more about it and supported platforms here.
