I never would have guessed that so many data centers ran their DHCP off of Microsoft Windows.

Active Directory and DHCP go hand-in-hand. Your Domain Controllers aren't always your DHCP servers, but under a certain scale, they very likely are.

  If you create a brand new domain, it will automatically configure it to be the DHCP server by default.

    That's true of DNS, not DHCP. One has to specifically install the DHCP role in a new AD domain.

  I'm a 20+ year Windows sysadmin and I don't buy it. If you'd said "Active Directory and DNS go hand-in-hand" I'd agree-- the coupling there is pretty tight (and it's a pain-in-the-ass to run Active Directory with non-Microsoft DNS servers being authoritative for the AD domain name). DHCP is a lot less tightly coupled.

I find this number also very surprinsing but it's not really 40% of datacenter, it's 40% of the networks monitored by Akama

  Yeah, I thought that too. Akamai seems to be popular with corporations.

Microsoft's Active Directory, DHCP server, and DNS server integrate very closely. When a domain member gets a dynamic IP address, the DHCP server will inform the DNS server to update its record for that host. Many companies are, let's say a bit lazy - when use an Active Directory domain anyway, you might as well use the DHCP and DNS servers, too, they handle replication and failover very smoothly. (I am not a big fan of Windows, but that part has worked pretty well in my experience.) You can get a similar mechanism to work between BIND and ISC DHCPD; it's not a lot of work, but with Zeroconf/mDNS it is less useful than it used to be.

Not the colo themselves running it, "in" datacenters. And more accurately, in networks in datacenters. Colocation means many clients, and in any given colo there's almost certainly someone running a Windows AD + Microsoft DHCP box, meaning it's "in" that datacenter. I'm surprised as many as 40% of networks still have that tech, but that's enterprise for you. Point being, though, it's likely in well more than 40% of datacenters.

In the 90s Microsoft tied their dominant Exchange/Outlook to Active Directory which depends on DNS/DHCP.

  Active Directory was officially only released in 2000 though.
