Add program to startup

• Select the Start(Windows) button, then select Settings - Apps - Startup. Make sure any app you want to run at startup is turned On.

If the application is not listed there:

• Select the Start(Windows) button find the app you want to run at startup.
• Open file location (from menu or right-click). This opens the location where the shortcut to the app is saved. If there isn't an option for Open file location, it means the app can't run at startup.
• With the file location open, press the Windows key + R, type: 'shell:startup', then select OK. This opens the Startup folder.
• Copy and paste the shortcut to the app from the file location to the Startup folder.
