Hi Stef,
Sorry, I didn't see those instructions, there's been a lot to read latey!
I went to the GitHub page, downloaded ran the add-store.cmd script, but just got the results below. It's saying that "...a higher version of this package is installed..." I think because in following Greg Carmack's instructions, I did download a bunch of appx files from the link he sent and I installed them yesterday.
I also ran the Add-AppxPackage -Path "Path_to_file.appxbundle" and got this:
===============================================
Also, it was a very good idea to create a new user to see if the Microsoft Store and Photos work there -- they do not! In the new profile, when I click on the icons, the window opens for a fraction of a second and then closes. So.....that leads me to think that it's hardware-related. I think there must be some driver for a piece of hardware in this laptop that Windows 10 doesn't have a good driver for yet. As I mentioned earlier, this is originally a Windows 11 laptop, but I can't stand working with it, so I did a clean Win 10 install on it.
Hmm, so the app doesn't open. It may, indeed, be a hardware issue, or the files that are required for the store don't work/are corrupt. Do you have more than 1 graphics card in your PC/Laptop? And if yes, is it a dedicated one or the CPU/integrated one?
And can you try running the same command again, but this time copy the thing that contains -ActivityID and run it. It will show something important.
