Great question! You can definitely lock individual pages in a long document to prevent changes from affecting other pages. Here's how you can do it:

1. Open your document in Microsoft Word.
2. Click on the page that you want to lock.
3. Click on the "Page Layout" tab in the ribbon at the top of the screen.
4. Click on the small arrow in the bottom right corner of the "Page Setup" section to open the Page Setup dialog box.
5. In the Page Setup dialog box, click on the "Layout" tab.
6. Under the "Page" section, check the box next to "Different first page" if you want to lock only the first page. If you want to lock multiple pages, select "Apply to:" and choose the pages you want to lock from the drop-down menu.
7. Click on the "OK" button to close the Page Setup dialog box.

Now the pages you selected will be locked and any changes made to other pages will not affect them. If you want to unlock the pages later, simply follow the same steps and uncheck the box next to "Different first page" or change the "Apply to:" selection to "Whole document".
