Since the versions are quite similar, I was able to make most of Windows 10 1507 look like 8.1 without third party apps. But, I did have to install StartIsback for the Taskbar, Windhawk but Windhawk doesn't work well with Windows 10 1507 and Windows 8.1. For the Metro apps, I decided to copy all the apps from an iso. Most of the apps were in "Program Files"\WindowsApps. However, Windows Store, Camera and Photos are in the Windows folder so I replaced it with the Windows 10 RTM version as an alternative as I couldn't install the Windows 8.1 ones on Windows 10. Most metro apps installed. Except three. Microsoft.Help+Tips, Microsoft.BingMaps and Microsoft.XboxLIVE. To install the other apps along with these three, I placed the correct AppRepository files (C:\ProgramData\Microsoft\Windows\AppRepository) from a fresh Windows 8.1 to Windows 10 1507 install. All the apps except those three installed successfully and works perfectly. However, those three apps don't install. Does anyone know why? The AppRepository files for the apps that didn't get installed gets deleted when I try registering the package (add-appxpackage -register -disabledevelopmentmode "C:\Program Files\WindowsApps\*app*\AppxManifest.xml") to install the app. I replace the *app* with the actual app name in asteriks. The AppRepository .xml files get deleted and it errores out with the error shown at the start of the post. How to fix this issue? I have copied the AppRepository .xml files to the root (C:\) so that I don't need to copy from the 8.1 install and the 8.1 install can actually run alongside. Thank you for reading!
