Delete Corrupted Built-in Building Blocks File

Resolve widespread page number failures by forcing Word to regenerate its corrupted Building Blocks file.

Microsoft Word relies on the Built-in Building Blocks file to load gallery items like pre-formatted headers, footers, and page numbers. When this file becomes corrupted, these features will disappear or stop working across all documents.

1
Close Word

Ensure all instances of Microsoft Word are completely closed.

2
Navigate to the Building Blocks Folder

Open File Explorer, type %appdata%\Microsoft\Document Building Blocks into the address bar, and press Enter.

3
Locate the File

Open the folder labeled with your locale ID (for example, 1033 for US English) and locate the 'Built-in Building Blocks.dotx' file.

4
Delete and Regenerate

Delete the 'Built-in Building Blocks.dotx' file. Restart Microsoft Word; the program will automatically regenerate a fresh, working copy of this file upon launch.

Automatic Regeneration: Deleting this file is completely safe. Word is designed to automatically rebuild it using default factory settings the next time the application opens.

Frequently Asked Questions

Why are my page numbers restarting at 1 on every page?

This usually happens when the page number format is set to 'Start at 1' for each section or due to hidden section breaks. Double-click the page number, select 'Format Page Numbers', and choose 'Continue from previous section'.

Can I insert page numbers without overwriting my existing footer text?

Yes. Instead of using a pre-formatted gallery option from the menu (which often replaces the entire footer), double-click to edit the footer, place your cursor where you want the number, and press Alt + Shift + P to insert only the page number.

Where exactly is the Built-in Building Blocks file located?

It is typically located in a hidden AppData folder at C:\Users\[YourUsername]\AppData\Roaming\Microsoft\Document Building Blocks\[LocaleID]. You must enable 'Show hidden files' in Windows to browse there manually, or simply use %appdata% in the Run dialog.
