Hi welcome to the forum.
These NET framework updates have raised a few questions of late.

Obviously only one of the said updates was installed on your computer?
Others you chose rightly to use 'Hide Update'. Which in essence means they are loaded, but not installed.
Having read a few threads on the various forums, including win7. The case seems divided.
But my own personal opinion is that as they are in 'Hidden Updates", you are not going to want them, you don't see them, they are not really doing any harm?
.I would leave them where they are.
Of course if you had this happening on a regular basis, we would have to look at what was causing the problem.
But as I suspect it is a one-off then I would leave them. Others may have a different opinion.
Windows Update - Windows Automatic Updating

Hello Zaniac625,

download the update program "Security Update for Microsoft .NET Framework 4 " from the Microsoft site, not Windows Update.

Security Update for Microsoft .NET Framework 4

go to Windows Update and see the installed updates. just uninstall the concerened update.

After uninstalling, reboot the system. then run the downloaded update to install it.

thats all. I think after installing manually it will not repeat. Thanks.
