TopMost works in Windows 8 but not Windows 8.1?

    Question

  • Hi,

    I'm writing an application, that needs to layer it's UI on top of all other windows when active, including the Metro Start screen.

    I'm using TopMost=true, and I modified the manifest to request UIaccess. I also signed the application, and put it in a trusted location...

    The problem, is that this works 100% of the time under Windows 8. However, under Windows 8.1 it seems to mostly not work. It seems to randomly work a few times, then mostly not work. By not work, I mean that it only puts the UI on top of other windows while in desktop mode. When I switch to Metro, the windows disappear.

    But like I said, it works 100% under Windows 8...

  • Update: Ok, I think I may have figured out what was going on, but not sure why it's the case.

    If I right click my app, and select, "Run as Administrator", it works.

    If I right click my app, select properties, then select "Run as Administrator"... When I run the app, it asks for admin, but then it doesn't overlay on Metro.
