Adobe Acrobat Windows 10 Free Edition BOOKMARK a PDF

@dadybear1234 No, you can't. The free edition of Adobe Acrobat (Adobe Acrobat Reader DC) on Windows 10 does not allow you to create new bookmarks in a PDF. Adobe Acrobat Reader DC is primarily a PDF viewer. While it can display existing bookmarks in a PDF and allow you to navigate using them, the ability to create, edit, or manage bookmarks is a feature reserved for the paid versions of Adobe Acrobat, such as Adobe Acrobat Standard or Adobe Acrobat Pro.

If you need to add bookmarks to a PDF, you would need to either purchase a subscription to Adobe Acrobat Standard or Pro. https://www.adobe.com/acrobat/pricing.html

These are the steps to create a 'Bookmark' if you have subscription to Adobe Acrobat Standard or Pro.
1. Open the Bookmark panel. Mine is on the left side

2. Select the second icon (in blue)

3. A 'Bookmark' panel will pop-out

4. Click on the first icon and click on 'New Bookmark,'

5. I am on page 1 of 2 page document. So, to make it simple here, I will enter page 1

6. Click on the next page. Repeat step #4, 'New Bookmark'

7. Enter Page 2

8. Now, you can flip back and forth on the Bookmarks
In my example, is my students assignment...
