Summarize:

Describe how long the problem has been going on and whether the issue has been consistent or intermittent. Be sure to describe any relevant circumstances about when your issues began, if the troubles began after a new install or the move to a new product, for example. Be sure to include all relevant details of your Microsoft device or product in your email, including the product key number if you have it. It should be located on the original packaging. Add any warranty information, if applicable, as well as the version of the product or program you're using. It is critical to include your contact information, so your Microsoft support technician can reach you to discuss the problem. Indicate in your message whether you'd like to be contacted back by email or phone, and if by phone, a good time for them to reach you.
Draft an email to wehelp@microsoft.com describing your issue. Include the product key number and any relevant warranty information. Bold your contact information so the support person can follow up.
