There is no SP2. The thing you installed was just a roll up of various updates till July 2016. It 2 years out of date. There have been a lot of updates since then. Plus some of the updates included in that 3172605 have been superseded.
That is why I suggested you use dism++.
It is not a disaster. You can get the newer stuff by using windows built in mechanism, or dism++ ( which is quicker and will warn you about telemetry junk ). Or you can use this which will get you the updates without the telemetry junk, but it is quite a large download. https://update7.simplix.info/UpdatePatch-18.7.20.exe
Whichever of the above methods you use, run cleanmgr afterwards. That will clean out the superseded stuff you have unwittingly installed.
