Does NW adapter powers off before Windows shutdown script is triggered?

Question

In my usecase i need to send API call upon Windows machine shutdown/reboot.

The script i created works as expected from the PowerShell console, but not when defined in gpedit.msc's shutdown scripts location.

I am assuming this is because WiFi adapter somehow gets down before the script gets executed. Added some debug prints and seems that it is a corect observation.

To prove it more i re-defined the same script in user login scripts location - and it worked as expected indeed.

My question is whether it is really correct that a WiFi adapter disconnects before the shutdown script steps into the process, and if yes - is there any way to outsmart it with PowerShell script?

(My theory is that trapping/delaying a WiFi adapter in a shutdown could adress the case, but even if i knew how to do that i smell the same issue here - the adapter will go down before the trap pops up...)

EDIT: the thing is definitely with the adapter power on shutdown call. If i define the User Logoff script - the script works even if i do reboot or shut down.

Answer 1

So despite i didn't find a way to intercept the NW adapter power supply on shutdown (as well as no comprehensive technical documentation of this feature), i definitely found out a way to acheive my usecase - define the user logoff scripts instead of shutdown scripts.
