I am trying to understand the history of a laptop.
The product key sticker on the back shows Windows 7 Home Premium as the OS.
Looking at the partitions themselves, one of them is labelled Vista (the
other two partitions are WinRe and Data).

If the laptop originally had Vista installed in the shop and it was
upgraded to Win 7 before sale, would this account for the different
partition labelling? Or is the Vista partition proof positive that the
laptop has had the OS reinstalled at some time?

I guess anyone using a PC or laptop that has been upgraded from Vista to
7 should have the answer to this one.

Firstly, the partition labels don't necessarily have anything to do with
the contents of the partition.

What operating system is currently installed?

I would expect reinstalling the OS to leave the partition labels
untouched.

Note that the original manufacturing process may have been upgraded so
that the partition image put on the partition called "Vista" contained
a Win7 operating system.
