Just to be clear, if you are referring to the yellow key it is suppose to be there... [IMAGE]it does look like an exclamation mark if something else then try to update driver or wait for the next new driver update.
Like the subject says, I have a yellow exclamation mark on the trusted platform module 2.0.  I can't figure out how to make it go away please help. 
Aurora R11, TPM 2.0, Windows 10 has yellow exclamation mark
