The new Windows 10 showed up unbidden on another of our computers yesterday and I've been trying my best to get a handle on this system but it is so crammed with boxes and icons and advice and new ways of doing things that I'm wasting a lot of time on this. The one thing I absolutely do not like is the "assistant" Cortana. She is intrusive and pops up constantly telling me she'd like to help. So I did a Google search to see if there was a way of disabling her. Here's the list of answers, few of which are understandable or helpful. There were 435,000 search items for this questions so I'm not the only one wanting to rid my computer of her.
Here's the first answer from Google: "Bring up the Start menu and start typing. Click on the "hamburger" icon in the left sidebar and choose "Settings". From there, you can turn off Cortana. To clear Cortana from the PC memory, either reboot or open task manager and kill Cortana."
Frankly, I never saw a hamburger icon and it's absurd anyway. So I kept going. I still have no idea if I've shut her off permanently or just for today.
