Error (0x80070643) for Windows Jan. 9th Security Update

So, (to keep this concise) I’m updating my craptop (my laptop is optimized for the standard source game setup) as I usually do, setting aside my afternoon to do so and then I get slapped with the error (0x80070643) while installing the security update. Note that the update was fully downloaded, without issue but installation is giving me trouble. I look it up and apparently it’s something with the .NET framework be busted or something. What should I do?
