how to uninstall .net framework 4.8 from windows 10

Question

I have windows 10 and .net framework 4.7.2 installed and my program works fine. Then I figured to try the .net framework 4.8, after installation, my program doesn't work. I was trying to uninstall .net framework 4.8, I did the uninstall from control panel, but the registry HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\Full is permanently set at version 4.8.03761. I've searched online for hours on how to completely rid of this 4.8 version to no avail. I also read that Microsoft made the decision that 4.8 version update to be irreversible, I am hoping this is not true and hope for ways that I can go back to 4.7.2 version without completely nuking the whole system and starting over.

.NET is part of Windows. New releases would appear as Windows updates in ARP (Control Panel -> Uninstall a Program -> View Installed Updates). To uninstall new .NET release, you would need to uninstall the correct Windows update.

Here are the update numbers for .NET 4.8 on Windows 10:

KB4486129 - for Windows 10 RS1/RS2 releases

KB4486153 - for Windows 10 RS3 and later releases

If uninstalling these updates does not fix the issue, I suggest opening a .NET issue on Developer Community web-site (https://developercommunity.visualstudio.com/spaces/61/index.html) and provide .NET installation/uninstallation logs.
