OK -- I FIXED IT.
Through a lot of trial and error.
Head to users/user/appdata/local/microsoft/windows/applicationshortcuts
Once there do a search for each file within application shortcuts using the search bar in the top right of the explorer, you might need to play with the search terms. For example, mine found the photo app when I searched 'modern' but not 'photo'. Odd.
I used the following terms, camera, microsoft ((for skydrive)), bing, modern.
You need to delete the little white shortcut tile (I had to adjust security settings first and give myself permission to delete within the app shortcuts file, but Windows will guide you through it.)
For the chat app, just delete and reinstall the calendar/people/mail group and its gone.
Hope it works for you guys too...
Thank you thank you thank you. After Win8.1 update, I basically lost access to all Apps (grey screens everywhere) and once recovered my PC from the last backup nearly all the apps needed repairing (btw weird double installs for each app - first install fails,
second one works). but I had 6 that either 1) no longer existed in App Store 2) equally weird names like "ms-resource:DisplayName" or 3) said app can't open and store couldn't repair. Been looking for days trying to find answers until came across yours via
a link on another site, did your suggestions and it worked. And yes finding them was a process of checking off the working apps until I found app folders that weren't listed under All Apps as the names can be cryptic or need logic.
However I needed to do a couple of extra things to finally make them completely disappear.
- I had to delete the folder of the bad app too, not just the shortcut in it.
- I had to go to the store, swipe to get settings and then go to App Updates. I then did both Check updates and did all the updates listed (may not have been related but just in case).
- Tapped Sync Licences to get everything "clean" again.
All the bad apps were gone, and I was then able to reinstall the ones I wanted again from App Store.
Major kudos to you, and major thumbs down to Microsoft for creating such a mess with little or no info out there on causes or easy repair. The App Store Troubleshooter was useless here.
How Windows users with no IT skills deal with this type of thing is beyond me....
