I am currently running Microsoft EMET (Enhanced Mitigation Experience Toolkit) version 5.0 (Latest Version) with the popular software list which protects other well known software as Google Chrome, Firefox, Windows Media Player............etc.

After upgrading EMET to the latest version 5.0, I noticed that the Windows Media Player (Latest Version 12) crashes and the below event log is reported.



My first suspect was EMET, I removed all mitigation for the Windows Media Player from the Apps Section as shown below.



Windows Media Player started working normal after removing all mitigation, I started checking them one by one till it crashes back again with the StackPivot Mitigation.

The StackPivot Mitigation is used to detect if the stack is pivoted and used to validate the stack register present in the context structure of certain APIs. For some reason its triggered with Windows Media player and you need to un-check it to work it out till Microsoft finds a solution since they are both Microsoft Products.
