Automate the troubleshooting of network issue caused by Windows 11 24H2 Update

After upgrading to Windows 11 24H2, some computer clients cannot access network via LAN or WLAN because of missing network gateway that the DHCP server cannot request. Manually typing the gateway does not help neither because it is lost again after system restart.

Bear in mind that this internet disconnection issue is caused by a Windows 11 24H2 update from Microsoft, and this is not an issue with your internet router.

The following is a PowerShell script to automate the following steps:

1. Open the Registry Editor and go to: HKEY_LOCAL_MACHINE > System > CurrentControlSet > Services > WcmSvc
2. Locate the entry called DependOnService
3. Open it and remove the line WinHTTPAutoProxySvc
4. Save the changes
5. Restart Windows Connection Manager (WcmSvc) service

To use this script:

• Save it as Fix-InternetConnection.ps1
• Right-click and Run with PowerShell (requires admin privileges)
• Accept UAC prompt if asked

Features:

• Automatic admin elevation
• Checks if modification is needed before making changes
• Preserves existing service dependencies
• Error handling and status reporting
• Service restart verification
