Somehow I corrupted the Windows Store. The Start Tile itself is working. It updates regularly showing new content. When I click the tile the screen morphs to the green full screen Windows Store. But it has the "merry-go-round" dots endlessly. Without the Store I can't download any apps. I can live without that ability but it would be nice to have.
I tried SFC but the huge report made no mention of Windows Store details. I tried a PowerShell script that was to refresh the cache. It didn't. I tried a regedit fix by tricking WS into recreating its cache. Didn't work. I didn't even find the cache where it was supposed to be. Didn' find it at all.
New sets of eyes and minds would be greatly appreciated!
As always TIA
