You are very close. But Office isn't the secret to Microsoft's unassailable dominance in enterprise. I could remove Office at work and we'd be okay. Active Directory is the key. A unified management of users, devices, groups, and policies that everything else is built on. Nothing outside of the Windows world even comes close. There's Linux tools to impersonate or talk to Active Directory, but no alternative to it. Group Policy lets me set up any number of tens of thousands of configuration changes and apply it easily to any group of users or computers with a few clicks, regardless of device manufacturer. Linux distributions aren't even consistent enough about which system tools are onboard, much less what policies can be configured on them. Web browsers all have Group Policy plugins, so everyone's web browser is configured by Active Directory too.
