    .NET framework prevents shutdown after Win8.1 -> Win10 upgrade


    Since I've upgraded from Win 8.1 to Win 10, I can't turn off my PC without getting an exception in .NET Framework, and then a message that it is preventing shutdown. Google shows that this problem isn't exactly new and already happened to some people with Win8, but for some reason I've not been able to find a working solution yet. Does anyone know of a way to fix this other than doing a clean reinstall (which I really don't want)?

    I've already tried some ".NET repair tool" from Microsoft, downloaded various offline installers of .NET and tried forcing them to re-install via command line. No luck - they just keep telling me that .NET is already installed, already a part of the OS, or sometimes even "installed but not activated", which is just plain wrong according to the feature selection dialog...

    Did you install dot net 3.5? You have to add it via 'Apps and Features"->Manager Optional Features->Add a Feature, it should be right on top. I haven't had any dot net errors.

    If it is related to NET app holding up shutdown, you might try this. Run as admin and restart.

    I did not install it specifically, but my features dialog looks exactly as your screenshot, so it's there.

    Took 2 restarts for some reason, but it worked! Thanks! Of course, I would prefer to somehow fix .NET directly (as the problem seems to be with it), but making Windows shutdown quickly no matter what is good too.

    For others: don't forget to run it with admin rights, otherwise it won't be able to modify these reg keys.

    I have tried running this multiple times as admin (with reboots in between) but it hasn't fixed the issue for me unfortunately. Does anyone have any other suggestions?
