Microsoft Support Phone Numbers
Finding information on Microsoft’s Web site is not always an easy thing. Unfortunately, Microsoft’s search engine is not very reliable so if you are trying to locate a Knowledge Base article or a certain document, use Google’s special search engine for Microsoft, rather than relying on Microsoft’s search which will often fail to locate documents on Microsoft’s own Web site.
The following contact information may be useful to you if you are looking for Microsoft’s support contact information in US or Canada.
