How to block all search engines except Google? [closed]

I'm using Windows 10 and I have a parental control program called Qustodio installed, but my child is able to bypass the security by accessing a search engine that isn't forced to use Safe Search, like yandex.com or others.

Is there any way - with Windows 10, Qustodio, or any other program - to block all search engines, except Google?

A solution for Windows and Android would be great.

Solution 1:

For Windows it's best to use the Windows Parental Controls.

This will allow you to review the websites frequented by your children and block sites that you don't like.
