Thank you for the reply, however I make it a habit of searching the forum prior to posting, so I already read those postings and did not get the desired results. However if it takes days to see results then I'm just impatient.
The events that led up to this situation is that I replaced my motherboard and defined a RAID 1 mirror as my boot drive. I could not do a system image restore because the RAID 1 overhead makes the drive appear just a bit smaller and Windows 8.1 will not do a system image restore even if, as in my case, less than a third of the drive was in use. This left me with no alternative but to reinstall the OS from the original DVD.
After finishing with all of the Microsoft Updates, I went to the store, signed on with my Microsoft User ID and restores all of my store apps. A few days later while probing my store settings I saw two entries for this machine since I rebuilt it with the same name. I was unable to determine which entry was for the previous machine, so I deleted both machines. I requested all of my store apps to be installed on the current machine. Tiles for all of my store apps were there the next morning, all with the "x" in the lower right corner. If I clicked on the tile I am given the opportunity to go to the store and repair that store app. I found I could repair only a single selected store app at a time, and I have over 200 store apps. I could not find any forum posting here or on Microsoft's support forums that allowed me to "Repair" all of my store apps at once. I looked at the PowerShell commands for store apps, but couldn't identify a command for the repair. I hoped to get a list of installed store apps and pipe that to a command to repair each one. I'm hoping others may understand the PowerShell commands better than I or that there is a document procedure other than manually repairing them one by one.
