Procedure:

Start->All Programs->MS Office-> MS Word
Open Microsoft Word and select "File" from the top menu. Then, click "New" and search for "business card" in the search bar.
Choose a business card template that you like and click "Create." The template will open in a new document.
Customize the template by replacing the placeholder text with your own information, such as your name, job title, and contact details. You can also change the font, font size, and color of the text to match your branding.
Add any additional elements that you want to include on your business card, such as a logo or a background image. You can use Word's drawing and formatting tools to add these elements.
When you are satisfied with your design, you can print your business card on cardstock paper or have it professionally printed.
Click on Close button to exit from the MS Word.
