Parental Control in Windows 10

I remember a time where you could set up a whole bunch of accounts on a local computer without having to have an email address. When I was younger my parents did this for me so that they could then restrict use to certain times of the day, week, and prevent my searching for inappropriate things. With how far Technology has  come in recent years and the release of Windows 10's developer's update my children are more than simply excited about the new laptop we bought. I have been trying as I might to set up parental controls for my two oldest children (only 8 and 10 years old). They will be using it for homework. My husband has his own business and was the primary reason we even bought the new laptop. 

My issue is that my children do not have email addresses and I absolutely do not agree with windows saying my children's information is SAFER by having an outlook account and therefore for me to set up parental controls for my kids' accounts not only do I have to have an outlook account but I also have to make outlook accounts for both of my children who are not even in middle school? I cannot limit their access to only one app so the "Assigned Access" is just simply not going to work. 

I want to know if there is a way that I can set up accounts for my children (just like a guest but with their own picture and account name) WITHOUT my having to tell my children to sign in with an email account? My children's information isn't on the web in any manor that is anything less than 100% necessary. My wanting to control the access to the internet when speaking about downloading viruses, viewing inappropriate images, or signing up for an email account of their own should not be dependent on them HAVING an email account. 

I'm sure I'm not the first parent asking the same question so the least that could be done is providing a different way of going about setting up restricted access to internet content and capability of downloading/modifying anything on the computer without admin (Parental) approval.
