Windows 10 installed painlessly over my old Windows 7. In starting web browser, it always asks if I want to make it my default. I click "yes" and it then opens a window to assign a calendar and email address to the browser. I do not want a calendar or email address assigned to this user ID, but it will not accept a default browser without email address and calendar. How do I get past this? Everytime I open the browser it asks the default question, but will not accept as default without email and calendar assigned. I'm ready to go back to Windows 7.
