Need help removeing .net 4.7.2 on Windows 2016 Data Center Servers

Need help to uninstall .net 4.7.2 on my Windows 2016 Server.

I installed .net 4.7.2 for my Exchange 2016 CU9 running on Windows 2016 Data Center.

After getting a million errors on my Exchange Servers I was asked to remove .net 4.7.2 and revert back to .net 4.7.1

I found no way on the Server to remove .net except for 4.6 3.5 and 2.0   4.7 does not show.

I did find this but not sure which is correct.
Open an admin command prompt and paste this script:
%windir%\\Framework64\v4.0.30319\SetupCache\v4.7.02558\setup.exe /uninstall /x86 /x64 /passive /norestart
If you have 4.7.1 as the latest version, this will run the removal tool. Reboot, and it will be removed.

What would the proper method of removing .net 4.7.2 be?

Can I use the above command? What changes would I need to make it work?

Thank  you,
LVL 23

When you go to add/remove programs click on view installed updates and see if you can find either of the below KBs, these will be the KBs for the web install of 4.7.2 or the offline install.


Select that and uninstall. Exchange doesn't support .net 4.7.2 so i would suggest looking at the below link in order to block that installation from happening again without your knowledge. I actually blocked this on my exchange servers because it will break exchange.

When I do that I do not see .net installed  see control panel image.

I went into the registry and found this see attached.

What about the command I posted?>

Ah KB4054590 in your screenshot is for .net 4.7.2, that is what you will need to uninstall.

I ran this also

461808 is 4.7.2

PS C:\Windows\system32> Get-ChildItem "HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\" | Get-ItemPropertyValue
 -Name Release | ForEach-Object { $_ -ge 461808 }

461308 is 4.7.1
PS C:\Windows\system32> Get-ChildItem "HKLM:SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full\" | Get-ItemPropertyValue
 -Name Release | ForEach-Object { $_ -ge 461308 }

Both came back as true.

So if I uninstall 4.7.2 then the 4.7.1 should be good still? or do I need to reinstall 4.7.1

timgreen7077Exchange EngineerCommented:
4.7.1 should still he fine.
