I am running Windows 10 Pro (Version 1809. OS Build 17763.437) and installed .NET 4.8 and afterwards learned that ILMergeGUI would not work with it. So I uninstalled 4.8 using “Uninstall Programs and Features,” and rebooted.

Now 4.7.1 is gone too, which was the version on the machine after a fresh install of Windows 10 on a new PC.

Yet when I try to install 4.7.1, I get an error that it, or a later version, is already installed.

And to top it all off, when I run this command:

reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v4\full" /v version

this is the result: 4.8.03761.

I have now done a restore using the restore point created when upgrading to 4.8 and I'm back to 4.7.03190.

Go to Update History -> Uninstall Update and then ...

Single installation:

Client Win 10: Uninstall Update KB4486153

Windows server 2016: Uninstall Update KB4486129

Update 1903:

Being a part of the Feature Update 1903, .NET 4.8 cannot be deinstalled except by a rollback to 1809 via control panel (Updates ->Recovery)

Requirements: Backup of 1809 is still existing under :\windows.old (Folder will be deleted 10 days after Update to 1903) and no disk cleanup has been done, as this deletes the folder too.
