Purchased points don't expire. Any points you get through promotions can have expiration dates. Typically, points expire within thirty days of the date you get them. To view any points in your account that have expiration dates, go to the Billing and Account Management page, sign in with your Windows Live ID, and then click Microsoft Points under Stored Credits. If you have points that are expiring in the next thirty days, you can click View expiring points to view the points and their expiration dates.
Note
You can only see points that are expiring in the next 30 days.
