Original Equipment Manufacturers (OEM) Support Numbers

Standard no-charge support covers most Microsoft products. If your Microsoft product was preinstalled, distributed with your computer, or if you obtained an upgrade directly from your computer manufacturer, your primary source for support is the personal computer manufacturer who provided your Microsoft software. Please check the documentation that came with your personal computer for information on how to contact them for support or see our alphabetical listing of computer manufacturers below.
