Read this tutorial Doing a Clean Install, will not bring you back to Windows 8

here are copies of the cbs & dism log
It states It did not find any integrity violations.dism.log

the CBS log states it is to large. ????

 

Since the SFC & DISM is done and did not find anything. I am going to do a RESET and see if it will fix itself. Thanks for everybody's help.

 

Ok Kathleen, but if I read your posts correctly, you've already tried Reset and it didn't work. If reset fails again, your only other choice just might be a clean install, Windows will find your Windows Key, and will activate once clean install is finished. You will have to re-install all your personal programs thou. You could make backups of your personal files, likes pictures or anything else, you need to save. But all personal programs would need to be re-installed again.

 

You need to clean install.
Click on link for a W10 ISO and download.
When done go to downloads, right click on link and choose MOUNT

Then follow instructions on screen
Skip when it ask for Windows Key as identification is already done when you downloaded the ISO.

Kathleen. Mike and Dencal are correct. Please don't run yourself around in circles. Make copies of all your personal stuff on an external drive of some type. Either a detachable USB drive or Flash drive or DVD. Documents, pictures, whatever you have. Please follow that tutorial for a clean install. You have a 64-bit machine, so make sure you are downloading and creating your ISO 64-bit. The link and Media Creation Tool will prompt you for all this, and guide you in making the ISO media. You need to boot from it to install. Just follow the tutorial.

 

Thanks for the logs
Its telling me its trying to mount 10Pro, and that theres an activation failure.

Have a look at this MS article.

Suspect a clean install will still have the same error

That doesn't surprise me seeing she has W10 Home installed....see post #29
If she clean installs W10 Home ISO all will go well.

 

Your correct,
She must have picked the wrong ISO on a clean install.
Thats WHY logs are handy.
Seen enough of them on Seven.

Where do you see that it is showing PRO? I am 99.5% sure I never downloaded PRO But.... I checked my machine and it is showing as Windows 10 core edition - in settings it shows Windows Home.

 

DISM log is showing as running a Pro repair.
Im assuming its trying that because of your product key.
run this tool

It will tell you whats on your system
DO NOT POST YOUR PRODUCT KEY

then read this sticky for an explanation

Hi Kaltland,
Whats showing when you do check product key part.

Roy

 

Anyhow, after not installing KB3211320 only downloaded KB3119986 and doing a reset, the system fixed the error (FOR NOW) it is no longer showing a pending service and I have 2 services listed instead of one in the registry.

 

Thank you all for your help. Have a great weekend.
