office key - Microsoft Community

so trying find out key comes computer or u have buy it

no office not "come with" purchase of new computer. 

for matter, neither windows.

both stand alone products have bought.  windows "comes with" computer, because builder paid ms it, , included cost, , fee install on computer.

many computers "come with" time limited "free trial" of office installed @ factory because  ms pays builders install it.

in past, computers came "permanent" copy office installed , activated because buyer paid it, less buying retail copy, extra.

in last year, computers "come with" free 1 yr subscription office 365 personal installed. user has activate license providing email account.  once again, paying it, don't know it.

to repeat, bottom line office not "come with" computer, have buy in 1 way or another.
