CurrentVersion value in registry for each windows operating system

Question

I want to know CurrentVersion value for each operating system at

HKLM "SOFTWARE\Microsoft\Windows NT\CurrentVersion"

For example: I have windows 7 professional installed on my machine and CurrentVersion value is 6.1.

Can any one list it down for all windows operating systems since Windows 98?

Answer 1

These are the required versions of windows operating systems:

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
Windows ME                      4.90
Windows 98                      4.10

If you want to know it by reading it from registry, you need to check the new CurrentMajor/MinorVersionNumber keys as well. 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.

You should be using WinVer.nsh to check the Windows version...
