Must Log-in Each Time ????????

kinda weird that with windows 10, you can clear the cookies and it still doesn't boot you out of your accounts. In a big way, I don't like that.

If you are using Microsoft Edge for browsing the directions for clearing that stuff is here.

Also note that Explorer still exists in Win 10 but you have to find it in the file system with Windows Explorer, as it isn't in the programs list in 10.
