About the Windows 7 support expiration.

If you live in a neighborhood you might want to look into wireless network sharing, as Win10 by default shares your wireless network password with anyone in your Microsoft address book (contacts in Win10)
This was a disturbing seeming 'feature' so I looked it up. Seems like the auto sharing of passwords was gotten rid of a few years ago and you have to intentionally set a network for password sharing. Did you say what you meant to say above?
