Windows 10 Hardening and management
We have about 10 Windows 10 Single user license computers & laptops and would like to harden them and be able to manage them somehow. They're all using Microsoft accounts and are all "Administrators", how do I change them to regular accounts then have an administrator account so that I can limit the accounts from changing critical settings, please note that they are not on a domain and I've only installed a NAS drive for backup and storage of other stuff. Any advice on how to make the management of these computers easy, we are not yet able to procure Windows Sever or any of that enterprise software and equipment.
