How can we check if the current OS is win8 or blue

Question

Win8.1 and Win8 has the same OS Version. How can we check if the current OS is Win8 or Blue? The Environment.OSVersion is giving us the same results:

Environment.OSVersion 6.2.9200.0 Environment.OSVersion.Version 6.2.9200.0 Environment.OSVersion.Version.Major 6 Environment.OSVersion.Version.Minor 2

Answer 1

Windows 8.1 will lie to you and tell you it is Window 8. Changing that lie requires editing the manifest that is embedded in your program so that Windows knows you don't want to be lied to. Project + Add New Item, select the Application Manifest File item template. Copy paste this verbiage underneath the <application> element:

<compatibility xmlns="urn:schemas-microsoft-com:compatibility.v1"> 
    <application> 
        <supportedOS Id="{1f676c76-80e1-4239-95bb-83d0f6d0da78}"/>
    </application> 
</compatibility>

Answer 2

I found a solution under this Registry Key

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
