Dear @Charles Kenyon,
Thank you for posting your question in the Microsoft Q&A forum!
I understand you're looking to eliminate the pink and blue mouse-over highlighting in Microsoft Word while keeping the squiggly red underlines for spelling errors.
Autocorrect and Highlight misspelled words features are helpful when you need to complete a big writing project quickly and don’t want to spend time proofreading every word. Your Windows computer highlights the misspelled words and changes them automatically so that you don’t have to spend your time on them.
In this case, here are a few steps you can try to customize these settings and check if it works:
Method 1: Right-click on the Start button and select Settings > go to the Time & language > click on Typing.
Here you would find 2 options namely Autocorrect mispelled words and Highlight misspelled words. Both have switches to enable or disable them.

Method 2: To turn Highlight misspelled words using Registry:
- At first, press Win+R, type regedit, press the Enter button, and choose the Yes option to open Registry Editor on your computer. After that, navigate to this path:
HKEY_CURRENT_USER\SOFTWARE\Policies\Microsoft
- Right-click on the Microsoft key, select New > Key and name it as Control Panel. Next, right-click on the Control Panel key, select New > Key, and name it International.
- Then, you have to create a REG_DOWRD value in the International key.
- For that, right-click on it, select New > DWORD (32-bit) Value, and name it as TurnOffAutocorrectMisspelledWords.
- Follow the same steps to create another REG_DWORD value named TurnOffHighlightMisspelledWords.
- Now, double-click on each of them to set the Value data as 1.

- Click on the OK button to save the change.
- If you want to turn them on again, open the same REG_DWORD values, enter the Value data as 0, and click the OK button to save the change.
