You seem to be under the misconception that there is only one
correct variation of English. Word's spellchecker includes the
following English variations:
• English (Australia)
• English (Belize)
• English (Canada)
• English (Caribbean)
• English (Hong Kong SAR)
• English (India)
• English (Indonesia)
• English (Ireland)
• English (Jamaica)
• English (Malaysia)
• English (New Zealand)
• English (Philippines)
• English (Singapore)
• English (South Africa)
• English (Trinidad and Tobago)
• English (U.K.)
• English (U.S.)
• English (Zimbabwe)

You don't say which ethnocentric, narrow-minded, bigoted part of
the world you live in, but you just have to tell Word and Windows
which English variation you wish to use. Of course, you are
always free to add whatever words you wish to your custom
dictionary, whether correct or not, and whether English or not.
And if you don't like Word's spelling of a particular word, then
you can add that spelling to your exclusion dictionary.

Can I get a list of English, not US, spellings to add to custom.dic?

If so where?

Or is there another way of making Word use correct spellings for
English users?
