    Those two updates were issued last year. One in July and one in October. Check to see if they're listed in your history as "Successful" or really missing. They might have been installed already.
    Even if they were 'successfully' installed, the fact that WU is picking htem out means that something is awry with them - and they need to be installed properly.

    ive done everything suggested except reinstalling NET framework, i refuse to do that. I guess ill just have to leave with these 2 security updates not being installed
    The advice is overwhelmingly to apply these updates.

    I have found with .NET Framework it is best to do one at a time.
    Reboot on completion.

    I agree Noel but the question is a diagnostic query. Perhaps the OP deleted or "cleaned" entries from the winsxs folder to try and save space.

    Tank - Run sfc /verifyonly from an elevated command prompt (Run as Administrator). Report back any messages you get.

    ok i uninstalled/reinstalled .NET Framework 4 and updated, it still wont install those updates. I noticed something, both the updates are for ".NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based" , According to my control panel the only .NET framework i had installed was 4, and not 3.5.1 like the update specifies it is for... Should I also install .NET framework 3.5, so i would have .NET framework 3.5 SP1 and also 4? In my computer> system properties it says i have "Service pack 1" on this computer.


    edit: i just ran that .net framework cleanup tool that was linked to in this site and that didnt work either. im totally out of options now. ive literally done EVERYTHING to fix this thing and im NOT reinstalling windows cus of this. Maybe i will call microsoft tech support tommorow

    i didn't touch the winsxs folder and i ran sfc /verifyonly from admin enabled cmd and it said no integrity errors were found

    what are you talking about one at a time? I have/had only the .NET Framework 4 on this computer, no other versions. Do i need to install other versions of .NET Framework along with 4? To my knowledge just having 4 was good enough.

    The .NET Framework versions are similar to the C++ versions in that you need them for software that was written for it. If you don't have .NET 3.5 installed, the updates won't apply. I'm not quite sure why WinUpdate pulled them down unless you've installed/uninstalled software that needed it. Hide the two updates if you don't have 3.5 installed.

    Did you not say in your Post 1
    .

    It is for updates:

    1.Security Update for .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2518869)
    Download size: 14.2 MB

    and


    2.Security Update for Microsoft .NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2572077)
    Download size: 11.0 MB
    Best to do / install one at a time IMO.
    In other words separately.

    Win 7 comes with .NET 3.5, .NET 3.0 and .NET2 already installed - .NET4.0 is merely an extension of functionality over the previous ones.

    There must be leftover from your previous uninstall of .net Framework v4.0 in the "Programs & Features".

    When you unistall it deletes most of it only, a part of previous security updates are left, therefore you'll have to dig them in the Tab " Show Installed updates" from "Programs & Features" panel.
