Stop Word from adding new styles automatically

Question

Using Microsoft 365. As I edit a document, new styles are added to the styles list.

I made sure the "Keep track of formatting" check box in the Advanced options is unchecked.

In the Styles options, I unchecked the three check boxes under "Select formatting to show as styles."

Still having the issue with new styles being added.

Answer 1

Go to File > Options > Proofing > AutoCorrect Options > AutoFormat As You Type and clear the last check box, "Define styles based on your formatting".

Answer 2

Could you give examples of those styles? Are they built-in styles?

For example, there is an option in the Style Pane Options dialog box to add more heading levels when you apply a heading style to text.

Answer 3

Thanks for the response. That option was not checked for me so there must be another setting somewhere.

Answer 4

Sure. I am not working with headings. I didn't notice the new styles at first so not sure where some of them came from. I have 3 that have hexadecimal names. I included a screenshot (below) of the properties of one of them. I use building blocks and after adding the text from the building block I modified a bullet in that text. Now I have a style with the name of the building block.

Answer 5

I don't know of anything that is built into Word which could create style names like that.

Are you running some type of add-in with Word?
