First, please be aware that you are not addressing Microsoft in this forum.
No one here works for Microsoft; we're all just other users like you, and
many of us are equally frustrated by Word's seeming inability (increasingly
in recent versions) to remember environment settings. Ultimately, the only
way to assure that you see the same thing every time you open a document,
template, or Word generally is a macro of some sort. Graham Mayor will
likely be along later to provide one.

I suspect that what you're encountering is "Personalized menus and
toolbars". Choose Tools - Customize - Options tab. Tick "Show Standard and
Formatting toolbars on two rows" and "Always show full menus".

Word should now do a better job of leaving things the way you found them.

Let's all settle down -- English is not a very precise language.  We
use the word "you" to mean "you, individually" "you all, as
individuals" and "your company."  This causes no end of trouble!  

Cleverly, many areas of the country have developed a workaround:
you'll, youns, you guys.  Unfortunately, those word cannot be used in
formal writing.  

Where did we English speakers go wrong?  Englished used to have two
different words for you-singular and you-plural.  They were "you" (for
you plural and/or you most honorable and high status individual), and
"thee" for (you singular and/or you, fella, informal).  

The Bible was translated using the informal version to refer to jesus
-- thee, thou, thine.  I guess the idea was that the original language
was written in an informal, friend-to-friend tone.  

So then we went and messed that one up too!  Now everybody thinks
"thee" is a formal word for "you" just specially for really high
status and important people.  

Gawd, we make a mess of this language.  

Oh yeah, everybody here's a volunteer and nobody gets paid by MS.  The
MVP's get something, but I haven't figured out what it is.  And
Microsoft doesn't read these groups, except maybe they do and don't
tell us.  And oh yeah, and the MVP's need to not trash Microsoft.  

Awaiting your responses with baited breath, I remain, yours truly,
