How may I un-install .net frameworkon a Windows Server 2012 R2 server

Hello,

In Windows Server 2008 R2, one may browse into the 'programs and features' module and look for .Net Framework to un-install a specific version and then to re-install it again later.  How can I find the .Net Framework 4.6.1 in Windows 2012 R2 so i can un-install that program?

If you are wondering why I want to un-install that program it is because it was suggested that I un-install and then re-install the .Net Framework in order to get another program to install correctly.

There is a module you can add to Server 2008 R2 (Windows Experience? or like) that allows you to see Windows Features on the server. You can remove .NET Framework in Windows Features.

right-click your powershell icon and run as administrator
1st command     Import-Module ServerManager
2nd command    Get-WindowsFeature  (This will show you all the features that are installed, to the left will be the long name and to the right will be the name of the feature installed or to uninstall)
After you find the netframework version you want to uninstall and it's short name
3rd command    Uninstall-WindowsFeature  nameofthefeature

If you want to uninstall any update related to .Net framework you can open programs and features, ensure that the view allow you to visualize updates and them delete that update.

If you want to uninstall .net framework completely, you need to make it using server manager.

You can open server manager from the start screen or the task bar. Then from the top Menu select Remove Roles/Features. Follow the online process to uninstall roles/features, and on the feature window, uncheck the .net framework component that you want to uninstall.

Does Powershell have you tied up in knots?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

No.

Windows server 2012 uses 'Server Manager' to add/remove features.

Yes. Same way as Server 2008. I have Server 2012 (no more 2008) and you can enable .NET Framework via Windows Features.

Schnellsolutions,
You may in fact use powershell to install/uninstall features/roles
Server 2012  Add-WindowsFeature or Uninstall-WindowsFeature  
Server 2008 Add-WindowsFeature or   Remove-WindowsFeature

view what is installed   Get-WindowsFeature

Of course, it also uses ServerManager (as a module in PowerShell. In the case of Win2008 we need to load the module, in 2012 it loads automatically). What I mean is that the roles and feature components of Windows Server are managed by 'Server Manager'. (Gui, PowerShell or DISM)
