Firewall rules change often

Hello,

I get often, from 5 to 15 minutes, a message saying firewall rules changed to Private/Low Risk Zone.
I wish I know the reason.
On one hand I didn’t get the mesage telling me it changes to other kind of zone.
On other hand, although I have one network adapter plugged in, I see different device set, twice each time:

RCS-RDS Residential (Marvell Yukon 88E8056, RO)

then

RCS_RDS Residential (Hyper-V Virtual Ethernet, RO)

where RCS-RDS is my Internet provider.

I have Windows 10 64bit Pro build 14393.

What might be the reason?

Thank you.

Hmm, I didn’t found that.
Sorry.

No problem.
