the Windows 7 Starter Edition is not a different operating system, it's just one kind of Windows 7.
And it's the lowest level edition, so you can upgrade from it to a higher level such as Windows 7 Home Edition.

Microsoft Word Starter is a (teaser) Edition of the Microsoft Office Package, it is a Basic Version of MS Word Professional .
A free pre-installed software to let the user do basic tasks of word processing.
But the full version of Word, called (MS Word) is more advanced feature packed of the MS Office package .
MS Word is a professional version and has more options and added features more than the basic (Word Starter).
Another differing point between the two versions is the price: Word Starter is free of charge, but MS Word ain't , so you must buy the MS Word in order to use it , of course you can try before you buy it, hence the license.
As for the Security, the less vulnerable version is Word Starter, because it has lesser user base and lowest features , so there little chance of malware to target it or the machine running it through another weak security hole.
In general it all depends of course on the Operating System security state, so if the system is more hardened that can lower the security breaches through any weak software points.

Microsoft Word is great and full featured, Starter have the basic and common things.
