  1. "Select an App to Open 'UserName'" shows up when i try to uninstall an App


    Hello!As mentioned above i'm running into an issue with "Select an App to Open 'UserName'" showing up. I had this show up once after turning on my Laptop, but it stopped after deactivating autostart programs in task-manager.Now i wanted to uninstall Discord, and this shows up again, leaving me unable to uninstall. I've looked up other options to uninstall discord, as it seems like this is not effecting all apps. Opening the Run dialog box The windows that opens when hitting windows + R i typed in %AppData% - and this threw me the "Select an App to Open 'UserName'" again.I made Windows Defend

    :)

  2. "Select an App to Open 'UserName'" Shows Every Time I Log In

    I disabled a bunch of startup apps and the "Select an App to Open 'UserName'" dialog no longer shows up. I don't know which startup app fixed it though. I had to manually add Teams.exe into the startup folder but it seems to work now.

    Thanks.

    Cannot open mail app settings


    OK, my next suggestion was going to be uninstalling Mail and Calendar and reinstalling from the Windows Store. You can have a go at this by following these steps.

    1. Open the Start menu, type Windows PowerShell.
    2. Right click on the Windows PowerShell and select Run as administrator.
    3. Enter the below command to remove the Mail and calendar app.

    get-appxpackage *microsoft.windowscommunicationsapps* | remove-appxpackage

    After performing the above steps, install the Mail and calendar app from the Windows Store.

    Hope this helps, you will, of course, have to add you accounts back again.

    "Select an App to Open 'UserName'" shows up when i try to uninstall an App

    Can I use MSI Gaming App OC profile in Afterburner and uninstall Gaming App?

    Hello all,
    I bought an MSI GTX 760 TF OC Gaming Edition GPU last week. Unfortunately the OC isn't programmed into the BIOS and to get the highest Factory OC I need to use the MSI Gaming App. The problem is it does not start with Windows or remember your last Clock Selection.
    I know Afterburner can start with Windows and apply your last selected profile.

    So can I......

    1. Open Gaming App and select OC.
    Open GPU-Z and see how much the Clock Speed has increased.
    Restore the default Clock (Gaming).
    Open Afterburner and apply the same increase to the clock value as the Gaming App gave me.
    Save the profile.
    Tick the 'Start with Windows' box.
    Uninstall the Gaming App.

    2. Will the above effectively apply the same OC as the gaming App and therfore make the Gaming App obsolete?

    3. Also I've read on some forums that Afterburner will only OC the MSI card if the gaming App is installed. I'm away from home so cannot test any of this. Maybe this was the case with the original version of the gaming app. can anyone confirm?

    4. Also I've read people reporting that once the OC has been applied it is locked at this high clock and doesn't downclock when idle. From what I've seen the Gaming App does downclock depending on GPU demand. As does Afterburner. Can anyone confirm?

    I don't know why MSI did things this way. It's a Gaming Edition card so there should be a way of applying the factory OC and leaving it set that way. The Gaming App is a nice simple little tool but as a bare minimum they should let us start it with Windows and automatically apply the last selected Clock profile.

    Dragging the shortcut into the start-up folder doesn't work for me. And even if it did, the last profile selection is not remembered.

    Many thanks in advance,
