Computer Manufacturers' Contact Information

Start here

OEM is an industry acronym for Original Equipment Manufacturer. OEMs are computer manufacturers that install software on their computer systems. Common computer OEMs are Hewlett-Packard (HP), Dell, Lenovo, Acer and Toshiba.

Microsoft OEM products are Microsoft products which were supplied with a computer or in the case of software, installed on computer by a computer manufacturer. This can include your operating system (such as Windows 7) and Office (such as Office 2010) products.

How did you obtain your product? Was your Microsoft product preinstalled (in the case of software), distributed with your computer, or obtained as an upgrade directly from your computer manufacturer? If the answer is yes, it is likely that you have an OEM product. For customers with an OEM product, the primary source for support is the personal computer manufacturer who provided the Microsoft product.

Not Sure?
If you are not sure whether your product is OEM or not, follow these steps to find out. If the letters OEM are included in the product identification number, then your product came with your computer. If not, then your product was purchased separately.

As your computer manufacturer has configured your computer hardware and software they would be the primary resource to contact for any technical support that might be needed. You may be entitled to free warranty support from your OEM. Click here for a list of computer manufactures with contact information.

What if I don't want to contact my computer manufacturer or my warranty has expired?
Depending on the product you need support with, there may be Microsoft support options available to you. They include:

  • Self-help support. For free self help support resources, please see the list of product solution centers and select the appropriate product.

    If your problem is related to one (or more) of the subjects above, then please select your product from the Assisted Support products list and submit your incident.
