The OP has solved the problem of Skydrive and it has, in his post, been deleted. As he says, he was aware that the name had been changed.
Deleting was a moot point, The change was made during an update. If the OP had already made a profile , and begun using onedrive, then he should have transferred all the items from skydrive to onedrive, and the deleted the skydrive directory. However, it is done now and I think he will find everything will work out ok
You can disable it, if you have no wish to use it, through the same "Charms" path. Microsoft are merely recommending, not forcing anything - it remains an option.
Many users, including myself, have third party hosting sites. For the capacity which MS provide for free, it is an option worth considering. I did, initially, uninstall it, but have since had second thoughts regarding the bottom line.
