DHCP Client - Windows Vista Service
Registers and updates IP addresses and DNS records for your computer. If this service is stopped, your computer will not receive dynamic IP addresses and DNS updates. If this service is disabled, any services that explicitly depend on it will fail to start.
This service also exists in Windows 10, 11, 7, 8 and XP.

Default Behavior
The DHCP Client service starts as NT Authority\LocalService and runs in a shared process of svchost.exe. If DHCP Client fails to start, the error is recorded into the Event Log. Windows Vista startup proceeds, but a message box is displayed informing you that the Dhcp service has failed to start. At least one service depends on DHCP Client. Therefore I do not recommend you to disable it.
Dependencies
The DHCP Client service won't start, if the following system components are stopped or disabled:
- Ancilliary Function Driver for Winsock
- NetIO Legacy TDI Support Driver
- Network Store Interface Service
If DHCP Client is stopped, the WinHTTP Web Proxy Auto-Discovery Service fails to start and initialize.
