I have a desktop with windows 8.1 and a surface 2 with windows 8.1. I have refreshed both a few times. This means that my Microsoft account thinks I have five different PCs when really 3 are old PC names that I reset or got rid of. This means that in the store when I click "my apps" I can see the apps I had installed on my surface before I reset it and the same for my old desktop account. This doesn't matter so much since I never look there, but I do look in the "other tabs" list on my L520 wp8.1 preview. And on that list is two surface devices. My current one, and the one before I reset it, which says there are two tabs open in IE11 even though that "PC" doesn't exist anymore! So... any idea how I can manage/delete these old non-existent devices from my Microsoft account?
