I cannot be sure if the Windows 10 version is the same as my Windows 7 version of the Desktop Weather app from TWC, but in my version you click on the gear icon near the bottom left to get the Settings menu, then click on App Settings. This submenu gives two options: Autostart App and Start Minimized. Click both of these to ON and it should give you what you want. Note that doing this autostarts the app minimized in the Systray, so you have to click on it to bring up the main screen. If you leave Start Minimized OFF, then it will bring up the main screen at its normal size whenever you reboot/restart. You can also get to the Settings menu by right clicking the temperature icon in the Systray and clicking on Settings. This is the way the app works in Windows 7; hopefully it works the same in Windows 10. Good luck!
