Windows 10: User account permissions need resetting.

I've converted my administrator account to a standard user account and created a new administrator account.

As a standard user I am able to access the admins user folder which I should not be able to do. There must some issues with the permissions somewhere but I'm not sure how to go about troubleshooting it.
@fdegrove has already suggested running an acl.bat as detailed here, post #39 Is a standard user account necessary for tight security and home user? - Page 4 - Windows 10 Forums

but it has not fixed my user permissions.

Has anyone got any ideas?

How to authorize my son to install software without my having to log onto the computer

Only an account with Administrator permissions can install software. Your son would need to log into a user account with Administrator permissions or he would need to know the password to an account with Administrator permissions.

 

Account type

Sign into Windows with an account that has Administrator permissions.

Control Panel > User Accounts > Manage Accounts > double click on the user you wish to demote > select Standard > click on the Change Account Type button.

A Windows PC only needs to have one user account with Administrator permissions. The other accounts, including your account, should have Standard permissions.

 

I wonder if my issue could be that the users folder is "shared"

I've found some information and uploaded some screenshots. I haven't applied the changes yet as I'll wait for another opinion even though it seems like a likely possibility...

You should not assign full permissions to everyone.
Here's the default permissions for C:\Users on my computer:

 

Mine looks the same. I think my issue is in the sharing section of the user folders. As you can see under the sharing tab "everyone" has full access.
