    So do I do
    DISM /Online /Enable-Feature /FeatureName:NetFx3 /All /LimitAccess /Source:e:\sources\sxs
    in an admin cmd prompt?

    Drive 'E' is where Windows 10 installed.

    Yes, at admin cmd. The "e" above refers to the drive letter assigned by windows when you mount the ISO for build 14342, not where windows is installed. Do you have the ISO? Do you still have the $BT~ folder from the build update in the root drive C? Please let me know these two things. It's fairly simple, but I need to know a few things first.

    Can you tell me where the $BT folder is?

    And what do you mean by "mounting" the ISO?

    And I'm not sure where exactly the ISO is... (that might be a problem)

    Pdragon, let's back up a little and get some basic info. What version of Windows are you running? Hold the Windows key down and press R. In the box, type WINVER and press enter. Please post a screenshot of that display. I'll wait.....

    pdragon... You are on the "current" public build of Windows Home. It looks like you have not done any cumulative updates and are running as a local account, not an MS account. The most current build is 10586.318. You have 10586.0. How long have you had this installed and where did you get the installation media?

    I got the media from the official Windows 10 microsoft website.
    Windows 10

    And I had this build ever since I installed Windows 10

    I had that build installed ever since I upgraded from Windows 8.1.

    So you upgraded from Windows 7 or 8. Are you running as a local account or do you have a Microsoft Account?

    The source for your media will download and, at your choosing, upgrade your system automatically. It's the Media Creation Tool. One more question (I think) before I get to a possible fix. Have you done a check for updates since you installed it? You should have gotten at least a cumulative update and a few other things, that would have brought you up to 10586.318. This is important.

    I have a Microsoft Account, and no, I don't think I have recently checked for updates.
