Sure, I can help you with that! The symbol you're looking for is called the registered trademark symbol. Here's how you can insert it into your Microsoft Word document:

1. Place your cursor where you want to insert the symbol.
2. Click on the "Insert" tab at the top of the screen.
3. Click on the "Symbol" button, which is located on the right-hand side of the ribbon.
4. Select "More Symbols" at the bottom of the drop-down menu.
5. In the "Symbol" dialog box, select "Arial Unicode MS" from the "Font" drop-down menu.
6. Scroll down until you find the registered trademark symbol (it looks like an "R" inside a circle).
7. Double-click on the symbol to insert it into your document.

Alternatively, you can also use the keyboard shortcut to insert the registered trademark symbol. Simply hold down the "Alt" key and type "0174" on the numeric keypad (make sure Num Lock is on). When you release the "Alt" key, the symbol will appear.
