Here's an update that may or may not help clear up Regedit32's confusion. Not being very techie I had no idea that is what the CB version was for. About 3 or 4 months ago, I turned the computer off one night. It had been on for a few days as I was busy and was doing some downloads of files at night. The computer had been working fine. The next morning I turned it on and it would not start. I turned it off and on two or three times with no luck. I unplugged it, removed the battery, put the battery back in, and turned it on again. This time it came on but very little was working. I ran Malware bytes and it found nothing, I ran chkdsk (a number of times, I think) and it fixed some stuff but not others, then ran a sfc /scannow, also a number of times, if memory serves. I'm pretty good about backing up the Registry files even if I'm only going to look at it and not make any changes. I tried using 3 or 4 older versions of the Registry backups, but that didn't help anything either.
I spent about 5 days, 16 hours a day working on this, I was pretty brain dead by this point. Somewhere, please don't ask when, where, or what prompted it, but I found a place that said I wasn't running the most current version of Windows and should update mine. Since my computer was still pretty sick and pretty much unusable, I did. And I thought I was getting that Anniversary version but evidently not. Remember, I was brain dead. Not sure I've recovered yet.
Anyway, many runs, many days, sleepless nights, many cups of coffee, many changes, updates, and only a few lost files, I managed to get it back to working. Trust me, I was amazed that I did it. And there was never any one thing that I did that Poof, made it magically all work again. With everything I did, it seemed that I got a little bit more functionality. Updating to this newer version of Windows seemed to help the most. Bear in mind, I'm not a techie when it comes to laptops. Give me a mainframe any day.
After doing that update, Cortana was back. I had found a way to turn it off in the Windows 10 Home that I initially put on the laptop. But it reared its ugly head again after I updated to whatever version is now on my laptop.
When I look in the Control Panel/System, it shows Windows 10 Home. See screen shot below.
However, when I look in File Explorer/System properties I see what is shown below. So, I understand your confusion and I am also confused.
The laptop was used and came with Windows 8.1. Before I started using it, I upgraded to Windows 10 Home, that free version MS had made available. That was another three months of trying to get that to work and I still can't set up a network with this laptop and my old one running Windows 7. But that is a battle for a different day, if ever.
As a side note, probably not at all relevant, I have ordered a new DVD drive, this one is dead, died right before all the problems. A new keyboard, this one misses keystrokes, so be patient with typos. And a new 2Tb hard drive as this one is getting quite full. It only has about 50 gb available out of 1Tb. I have lots of instructional videos and lots of research material for various writing projects. And I ordered a new fan, just in case.
I'm currently in Costa Rica trying to find a buyer for my beach house here and have to have everything freight forwarded to me which is why I ordered so much at once and a fan, just in case. Computer parts are not available here and neither are competent technicians to fix them. If I'd been in Arizona I would have taken the laptop to the repair shop when I first turned it on and it wouldn't work.
So, there. You have a more or less complete history of this laptop and my troubles with it. I hope that helped with some of your confusion.
