    Cant open any Windows App with UAC disabled

    I disabled UAC and when I try to open Edge, Calculator, etc I get a window message that says that I cant open it with UAC disabled, I find it something very annoying that makes me think about going back to Windows 7, is there any around this?
    In Windows 7 for example, I was able to open the calculator with UAC disabled.

    You cannot open any universal apps with UAC disabled, because Universal apps run in sandboxes that are based on UAC functionality. It was the same way in Windows 8.

    Some apps have moved from desktop apps to Universal apps in Windows 10, such as the calculator. Edge is also a universal app. Settings is also a universal so, with UAC disabled, you can't access settings either.

    Basically, disabling UAC cripples your computer now, and you can't run without it effectively.

    Thanks for your answer, didnt know that Windows 8 was the same about it because I was still using Windows 7. I never liked the UAC stuff, will try to use it a bit more to see it better before take the decision to go back to Windows 7.

    Disabling UAC poses a huge security risk. If you download a fake Adobe Flash Player installer, for example, you would usually be able to tell that it is fake when you run it and the UAC dialog box pops up telling you that it is unsigned. Without UAC, you would have to manually check in the Properties. You don't even need to run the file yourself. Some viruses can automatically execute from infected removable drives, and without UAC, you would be infected. You can disable the way UAC blocks the desktop by searching for "UAC" and clicking the first result then dragging the slider to the second from bottom position and clicking OK.

    @You I will be the judge of the risks. I had even to disable running in elevated mode in the policy editor. Because when running xplorer2 you can't create a folder in "Program Files" in normal mode, but in elevated mode it's running in the administrator account meaning that all your networkdrives have to be configured again.
    Anyway, prompting does not solve any risks as one tends to press on ok without reading the message after ten prompts or so. The only solution is virus-scanning and checking the source (url) yourself when in doubt.
    So I hope someone finds a way to run apps with all this disabled. In the meantime I will refrain from using them on the desktop.

    That is odd, Calc, Edge, Store run just fine with UAC disabled, maybe an update fixed that?

    @TairikuOkami It turns out that the lever in the lowest position does not mean that UAC is disabled. Only "disable running in elevated mode" in the security policy editor does turn off the service entirely (restart necessary). I have not been able to identify a separate service that can be stopped or run or other methods of turning it on or off without a restart. But maybe someone knows

    Indeed, the op did not specify, that he used an advanced way of turning off UAC, using EnableLUA.

    To be fair to OP, dragging the slider to the bottom doesn't disable UAC, and also doens't imply it is disabled.

    OP: I have the same gripe as you. looks like it's turning back on until such time they reimplement the win8 version of calc.
