Reliable way to get Windows Version from registry

Question

I\'m checking the windows version in an installer (made with NSIS) by checking the following registry key:

HKLM \"SOFTWARE\\Microsoft\\Windows NT\\CurrentVer         


        

Answer 1

Instead of reading the value CurrentVersion, read the new values CurrentMajorVersionNumber (which is 10) and CurrentMinorVersionNumber (which is 0) under Windows 10. Those 2 keys are new in Windows 10 to detect Windows Version from Registry.
