Not really. Almost every Windows-based organization over a certain number of employees will use some shape or form of Active Directory (whether on-prem or in Azure) and most likely also Office 365, which is corporate/enterprise infrastrucure that is really hard to migrate away from once you built your IT and processes around it.

All the license fees for just retaining access to and being able to onboard new employees in that infrastructure is a huge portion of the budget for these organizations.

They just gave up the war on competing with UNIX/Linux on the non-enterprise production infrastructure side, since there were no money to be made there.
