Only companies are able to publish desktop apps and it is doubtful this will change.
Are you able to accomplish what you need to accomplish with a Windows 8 interface app?

Then allow at least changing an individual account to a company account. I've created 2 years ago my Windows Phone dev account as individual, not knowing that this would be a limitation 2 years later in the Windows 8 store. Now I cannot publish my desktop app
without creating another dev account, which I won't do (I already have listed my metro style app).
