Porn 🍆 - Parental Controls On ✅ but Google SafeSearch off ‼️

Very good question.
You are making the wrong target that's all.
In Windows the parental controls are provided in 2 steps. Account access and Internet Options ASDC""? provider.
In Windows your parental accounts are blocked from every web site until you make an allowed list. Create a user account, also found in Control Panel.
In the router settings that is controlled confidentiality through an app or router settings.
You may have just turned on a basic feature. You actually need to block websites.
And by the way. Google and other search engines are not qualified for parental control settings.
If you want to allow your children access to a search engine. You have to do more. Because no matter how much you block they will still get a search preview in the page. Even if they will not be able to visit the site.
Every Search Engine has their own parental control option. You have to visit the desired search engine website and create a custom search page, rather advanced custom search page.
For example if your favorite search is Google.

There you are creating an account for that child. And then you are only allowing that child's account to be used on that computer with a restricted account and a custom search tool.
It's rather called a search tool.
That's all I can say for now.
Again. The best parental practice is too block search websites before you get familiar with their parental monitoring. They are not responsible for search communications.
