Visit Microsoft's Windows Support page to find contact information and support regarding your Windows operating system. There you find links to contact Microsoft directly, by phone, mail or Web, or to the Microsoft forums, where other users can answer your questions.
Should you desire to speak directly with Microsoft, simply click the "Contact Us" link and choose the category that you need help with. If you require in-person help, click the "Find a Microsoft Store" link, look at the heading for your state, and select the location closest to you. Note the store address, hours and phone number, and then contact them at your convenience.
