If I'm in CMD I can use winver

enter image description here

I can see my OS version is 20H2 now. But this is GUI result, I want to use command line to make it. If I use

ver

Microsoft Windows [版本 10.0.19042.868]

If I'm in powershell, I can use

Get-ComputerInfo WindowsVersion

WindowsVersion
-------------- 
2009

So how to get the version like "20H2" in command line(powershell or cmd)?

The value can be found under registry key Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion inside the value named DisplayVersion.

The following PowerShell command will get it:

(Get-Item "HKLM:SOFTWARE\Microsoft\Windows NT\CurrentVersion").GetValue('DisplayVersion')

    You might want to point out that DisplayVersion does appear to have existed before 20H2. On my 1909 system it returns nothing. – Ramhound Apr 08 '21 at 14:31
  • @Ramhound: Strange. But anyway, DisplayVersion was the only value in my registry that contained the string 20H2, so without it one needs manually to map the numeric value of ReleaseId to a name. – harrymc Apr 08 '21 at 14:54
  • Microsoft changed from using Version 2004 to Version 20H2 with the release of 20H2. It appears that ReleaseId is still the YYMM date format. – Ramhound Apr 08 '21 at 15:03
