If you have a valid Windows license, you are eligible for support from Microsoft, subject to the Microsoft Lifecycle Policy and the support terms and conditions that were in place at the time of purchase. If you acquired your Windows operating system through the Microsoft Volume Licensing program or from an Original Equipment Manufacturer (OEM), Microsoft offers access to a wealth of online self-help support content in addition to paid technical help offerings. If you acquired your Windows operating system through an OEM, you may also contact your OEM for more information about the support offerings for Windows operating systems from that OEM.
