Spell Check not working.

If your spell check function in Microsoft Word is not working and it indicates that the check is complete even when there are misspelled words, there are several potential causes and solutions you can try:

1. Proofing Tools Not Installed: Ensure that the proofing tools are installed. You can do this by going to the Control Panel, selecting Microsoft Office, and modifying the installation to include proofing tools.
2. Speller Add-in Disabled: Check if the speller add-in is disabled. Go to File > Options > Add-Ins, and at the bottom, change the dropdown from COM Add-ins to Disabled items. If you see Speller EN-US (nlsdata0009.dll), enable it.
3. Check Spelling as You Type: Make sure that the Check spelling as you type option is enabled. Go to File > Options > Proofing and ensure the box is checked.
4. Language Settings: Verify that the correct language is set for the document. Select all text, go to the Review tab, click Language, and then Set Proofing Language. Make sure the Do not check spelling or grammar box is unchecked.
5. Registry Issues: If none of the above methods work, there might be a registry issue. You can check the registry key at HKEY_CURRENT_USER\Software\Microsoft\Shared Tools\Proofing Tools\1.0\Override and ensure it is set correctly.

After trying these methods, restart Word and check if the spell check functionality is restored.

Which version of Word are you using? Some do not have the Editor.

Desktop or online?

Can you provide a sample document with a couple of words that should be marked as misspelled but are not marked?

You can save such a sample on OneDrive or DropBox and post a link here. More about that: https://addbalance.com/articles/Why%20a%20sample%20file%20is%20important%20for%20troubleshooting.%20How%20to%20do%20it.htm
