Preventing Skype for Windows 10 (Skype UWP) from starting
D'un autre côté, if this is the Skype UWP app those options won't be available. Based upon a similar question on the Microsoft Answers web page, their Skype Community Moderator explained what needs to be done:
The new Microsoft Skype for Windows 10 (Skype UWP) application has
never been present in the Startup tab. Windows apps are not managed
the same way as a Win32 application. The classic Skype for Windows
Desktop is a Win32 application, Skype UWP is not.
If you close your computer without signing out of the Skype UWP
application, then on next computer boot, Skype will auto run in the
background. To maximize Skype UWP you will just need to cliquez sur the
application icon.
If you prefer not to be signed in automatically on Skype for Windows
10, vous pouvez sign out from the app. We won't sign you in automatically
après cela.
Autrement dit, Skype UWP users simply need to logoff from within the app to prevent it from starting automatically during a subsequent Windows 10 login.
As a potentially viable alternative to the Skype Community Moderator's advice, vous pouvez turn off the background app functionality for Skype. Naviguez vers the following location:
Start > Settings > Privacy
Ensure that you have selected Background apps à gauche-hand side, scroll down à droite until you trouvez le entry for Skype and change the slider to Off.
That being said, in addition to the obvious advantages there are minor drawbacks to using this method:
Bear in mind that there’s a downside to this. If you prevent the
Alarms app from running in the background, par exemple, any alarms you
set won’t go off. If you prevent the Mail app from running in the
background, it won’t notify you of new emails. Apps normally run in
the background to update their live tiles, download new data, and
receive notifications. Si vous voulez an app to continue performing these
functions, vous devriez allow it to continue running in the background.
If you don’t care, feel free to prevent the app from running in the
background. Vous pouvez still use the app normally, but you may have to
wait for it to fetch new data after you launch it.
Uninstalling the classic Skype application
Taking it a step further, si vous voulez remove the application entirely, the classic Skype Win32 application will be listed within the Programs and Features applet in the Panneau de configuration. Simply highlight the Skype entry in the Name column et sélectionnez the Uninstall button near the top.
Uninstalling Skype for Windows 10 (Skype UWP)
In contrast, the Skype UWP app won't be found in Programs and Features. En conséquence, si vous voulez remove that particular version, naviguez vers the following location:
Start > Settings > Apps
Ensure that you have selected Apps & features on the upper-left, scroll down à droite and left-click Skype to select Uninstall.
Notably, if the Skype UWP application is already running, before attempting the Uninstall vous devrez peut-être first select Advanced options, then choose Terminate to "Immediately terminate this app and its related processes." Après cela, select Uninstall as desired.
