The "48 in 1" part of the product turned out to be a huge advantage. Emma's laptop was a few years old, and she wasn't sure if it would be compatible with the latest versions of Windows 7. But with this DVD, she had access to 48 different versions of the operating system, including various languages, architectures (32-bit and 64-bit), and editions (Starter, Home Basic, Home Premium, Professional, and Ultimate).
