Hello Windows Forum,
Windows 8.1 has once again threw the same issue to me for a third time. Most App tiles apppear with an X in the bottom right and fail to launch. I Have tried every researched answer and after boot it's all over again.
Things I've tried:
Windows app diagnostic troubleshooter...
admin rights
app synchronization
apptiles
boot issues
chkdsk
cyberfox
diagnostics
dism
hp desktop
powershell
registry
reinstall
resolution
safe mode
sfc
system restore
system specs
system tray
