The Lenovo IdeaPad 3 15 Laptop, model number 81WE00NKUS, ships with Windows 10 S-Mode 64-bit Operating System. Windows 10 S-Mode provides added security by only allowing APPs available ( and therefore certified by Microsoft) at the Microsoft Store. If you don't need the added security or you need to install APPs not available at the Microsoft Store, you can switch to standard Windows 10 Home 64-bit Operating System, at no additional cost. The Zoom App is not available through the Microsoft Store, so in order to install it, you will need to switch out of S-Mode and into Windows 10 Home 64-bit Operating System first. Here is a link to instructions for switching from Windows 10 S-Mode to Windows 10 Home: https://support.microsoft.com/en-us/help/4456067/windows-10-switch-out-of-s-mode
