    Are you attributing this to KB3121461?

    So ,on my Desktop I decided to install each update one by one, restart and run sfc/ scannow after each one to check for corruptions. Chose the desktop cause it's pretty fast and can get through the sfc/ scannow pretty fast. After about 6 updates with every going smoothly I hit a snag with KB3121461, file corruption just as before. I uninstall KB3121461, restart then no corruptions with SFC/ scannow. I leave this out for now and finish the list, restarting and sfc/ scannow after each one with no problems. At the very last I try KB3121461 again and same thing, file corruption. Tried installing again and same thing.

    On my laptop I installed the whole list except for KB3121461 successfully with no corruptions then after installing KB3121461 I get corruptions. So at least for my PC's KB3121461 is causing problems so I am going to let that on sit for a while. I have encountered false positives with scf/ scannow before and this is acting the same way. I will try KB3121416 again in a couple of days.
    Interesting, I have that one installed and got no corruption after the install. Just checked again and no corruption.

    No, after removing it the inventory agent DLL is still marked.

    Currently I had removed 3 updates, 2 randomly chosen and updates 1 & 2 installed again.
    1. KB3121461
    2. KB3124275
    3. KB3123479

    Update 3 hasn't yet been installed, after installing update 1 the corruption has returned.
    Updates 2 and 3 have been removed after each other as I wanted to start with removing everything at once and update 2 didn't require a reboot for removal.
    I find it however odd that after removing update 1 the corruption was still there, but after removing the other 2 no corruption was present anymore.

    Code:
    2016-01-16 12:45:01, Info                  CSI    00000960 [SR] Repairing corrupted file [ml:520{260},l:46{23}]"\??\C:\WINDOWS\System32"\[l:24{12}]"invagent.dll" from store
    EDIT: I have been able to find out that both updates
    1. KB3121461
    2. KB3123479

    have caused it on my system.

    I am at a point right now where KB3121461 causes the file corruption every time I install it. Everything else is installed with no corruptions. Last night I tried installing KB3121461 two more times on both my PC's and same thing. Funny though, when I uninstall KB3121461 it requires a restart but I need to restart a second time to get a clean sfc/ scannow. The only thing I never did try was installing KB3121461 first without all the rest.

    I've just installed the updates including KB3121461 and SFC /SCANNOW shows no errors. Maybe only a few users have this problem or MS has fixed it?
