I'm sorry to hear that you're having trouble finding the Design tab in Word 2007. The Design tab is where you can find options for formatting your document, including adding a header to page 1.

It's possible that the Design tab is hidden or not enabled in your version of Word. Here's how you can try to enable it:

1. Click on the Office button (the round button in the top left corner of the screen).
2. Click on Word Options at the bottom of the menu.
3. Click on Customize Ribbon on the left side of the screen.
4. In the right-hand pane, make sure that the checkbox next to the Design tab is selected.
5. Click OK to save your changes.

If the Design tab still doesn't appear, you can try resetting the ribbon to its default settings:

1. Right-click anywhere on the ribbon (the area with all the tabs and buttons).
2. Click on Customize the Ribbon.
3. Click on the Reset button at the bottom of the window.
4. Click OK to confirm that you want to reset the ribbon.

As for your frustration with Microsoft Help, I understand how you feel. It can be difficult to find the information you need, especially if you're not sure what to search for. One thing you can try is using more specific keywords when searching for help. For example, instead of searching for "Design tab missing," you could try searching for "How to add a header to page 1 in Word 2007."

Regarding your question about why Microsoft changed the user interface in Office 2007, the main reason was to make the program more efficient and easier to use. The new ribbon interface was designed to make it easier to find the features you need, and to provide more context-sensitive options based on what you're currently working on. While it can take some time to get used to the new interface, many users find that it ultimately saves them time and makes them more productive.
