How can I add a Word to Windows 10 Auto-Correct?

Windows 10 has added an Auto-Correct feature for typing. I want to be able to edit the dictionary. This document says that I should be able to find it here:

%AppData%\Microsoft\Spelling\\default.acl

I've found it, but it's just an empty file. How do I edit this thing?

Answer

I found this out from: https://www.tenforums.com/tutorials/25994-spell-checking-dictionary-add-remove-words-windows-10-a.html

They document two ways to do it.

1. 
   

   Add highlighted misspelled words with right click "Add to dictionary"

   
   


2. 
   

   Add or Remove Words in Spell Checking Dictionary default.dic file for a Language

   
   

   Here you put word in the %AppData%\Microsoft\Spelling right dictionary for your language. Open the default.dic file with Notepad. Put word in plaintext. One per row.

   
   

Hope this helps.

EDIT:

For auto correct you add words in the default.acl directory as " autocorrect pair with the words separated by a vertical bar ("|") (in the AutoCorrect word list)" (See Microsoft page dictionary files section).

For example, if you wanted to change misspelling mnger to manager, then you would add this line in .acl file:

mnger|manager 

I tested it now. I had no spaces between words and the pipe.

Plus, please make sure "Autocorrect misspelled words" is on in Settings.
