After updating to the new Windows 11h2, some machines experienced network issues with both cable and Wi-Fi. They connect but don’t get network access and receive an IP address starting with 169…, resulting in no internet or network connection. I updated drivers, firmware, and reset the network settings. The machines’ MAC addresses haven’t changed. Does anyone know what could be causing this?

I believe it is disabled because WPAD is a known security vulnerability. Look at the description on that service and it refers to WPAD. WPAD should have been disabled in any secure configuration via GPO or other secure config management tool. WPAD has not been required for around a decade or more.
I had the same issue after updating to 24H2. Luckily i could recover 23H2 from a system image. The only way i can update to 24H2 and retain the wifi setting (mine disaapeared altogether) is to install the update via a mounted iso of 24H2. the download is avialable from Microsoft.
So For my issue, (at least on one machine, we have 2 right now with the problem) the WinHttpAutoProxySvc was disabled (from install). Made this change to the registry here: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WinHttpAutoProxySvc"Start"=dword:00000003 rebooted and resolved our issue. Internet back and working without anything else.
Not sure why this would be the case but it worked, I will try the other system and let you know.
***UPDATE***
Maybe spoke too soon! Not shocked, but when we rebooted that machine again (after the initial reboot and the internet was working on WIFI) the Start DWord in the registry had gone back to 4. And the internet did not work until the registry was changed and rebooted again.
So not sure what to say now.
If you have AD check if any GPO disable this service. The problem solved for me as you say with registry key.
Hi, I tried it on 2 desktops, one laptop and one Surface and removed this WinHTTPAutoProxySvc , rebooted the workstations and it worked. Windows 11 23H2 does not have this dependency.
just for reference, in "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Wcmsvc
DependOnService" I have only "RpcSs". But let's see if someone else can fix the issue using your solution.
