We have in the past pushed back on just having golang call out to powershell to do things. If we wanted to do this, we could just use upstream's powershell scripts in the first place, instead of handling cni setup in golang. Why do we need a powershell script to check a registry key and reinitialize hns?

It needs to check the latest reboot. If Calico os starting after a reboot it has to clean the network if it's after a restart of RKE2 the network shouldn't be cleaned. I can try to do the check inside golang.

You're still execing powershell. You should be able to do this using pure go. See for example: https://gistlib.com/go/get-system-boot-time-in-milliseconds-in-go

I was searching for something similar but it seems that syscall it's not working properly on windows. I tried that code and it's not building. I'll try to check if there is something similar.

I did something similar using a different function. Now I'm not using any exec command so I also removed the context and left as it was before.

Proposed Changes
This PR move the delete of all networks on a script that does as Calico that checks if the node is rebooted only.
The fix right now works only if the other version has already the new script check updating from an older version requires a node reboot and the bug is fixed from the next version updates.
