All versions of Windows include DHCP client software, which is installed when the TCP/IP protocol stack is installed on the machine. DHCP clients obtain a DHCP lease for an IP address, a subnet mask, and various DHCP options from DHCP servers in a four-step process: DHCPDISCOVER: The client broadcasts a request for a DHCP server. Similar to vendor extensions, DHCP options are tagged data items that provide information to a DHCP client. The options are sent in a variable-length field at the end of a DHCP message. For example, the DHCP Message Type is option 53, and a value of 1 indicates the DHCPDISCOVER message.
DHCP Client is a Win32 service. In Windows 10 it is starting automatically when the operating system starts.
