I bought an iPod last week for the first time in my life and want to access iTunes (yes, I know it's now 2015).
My six-year old computer runs on Windows Vista with which you can no longer download the iTunes program. You need at least Windows 7 to do so.
What is the cheapest way to get hold of a (safe) upgrade to Windows 7 or 8 to tide me over until I get a new computer, hopefully early next year?
