Hi, As you can see for yourself, the initiator deletes the CHILD_SA in every case. Windows 10's VPN implementation was broken a lot of times in the past, so I wouldn't be surprised if they did not implement inactivity timers and reestablishment correctly. AFAIK the Windows 10 VPN implementation does not try to keep the CHILD_SA up at all times and you can't change that.
Kind regards
