Windows 10: Cannot enable .NET Framework

After having disabled NET Framework 3.5 and .NET Framework 4.8 to getting my PC to install the latest troublesome Windows Update, I have to re-enable them. But Windows can't do the change, and I get the error 0X800F0806. Doing a google search doesn't help. I tried the trouble shooting thing, no luck. Others suggest to reset the updates.... it's not going to happen! Took me 2 days to get one update installed and 3 days to get the next updated installed by force. So I am not removing them again.What good does these .NET Framework do for my PC? I can't really find out, if it matters to have them
