Block download on windows 10
Open the Start Menu, and click the Settings gear icon. Choose Network & Internet. Select Wi-Fi on the left. Under Metered connection, flick on the toggle that reads Set as metered connection. There should be a setting somewhere to block downloads. If you block a computer from downloading anything, it cannot use the internet at all. If you want to prevent your child from installing software, have them use a Limited Account rather than an Administrator account.
