Windows 7: "Illegal operation attempted on a registry key marked for deletion."

18 Jan 2017   #1

Windows 7 Home Premium 64bit
"Illegal operation attempted on a registry key marked for deletion."

I just reinstalled a fresh copy of Windows 7 on my laptop, and when I went to download Windows Updates, it threw me this error message "Illegal operation attempted on a registry key marked for deletion." with the error code 800703FA. I also tried to run the .NET Framework installer and got the exact same message. I looked the error up and it's my understanding that it is a registry error? This doesn't make much sense though, as this is a fresh install of Windows.
