Persist Internet Connection Sharing after Reboot

In my previous post I wrote about how to use Microsoft's Internet Connection Sharing to share an internet connection on a Windows machine with a Raspberry Pi. Unfortunately, I learned that the ICS service settings do not persist after the Windows machine reboots, and as a result the ICS connection is lost.

The fix is explained in this Microsoft Learn page.

To fix the issue, add a key in the Windows registry with the following information:

• Path: HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\SharedAccess
• Type: DWORD
• Setting: EnableRebootPersistConnection
• Value: 1

I then had to reset the shared connection by unchecking and rechecking the boxes in the Sharing tab of the internet connection as explained previously. After a reboot, I confirmed that I could connect to the Pi without manually re-enabling ICS.
