Please post your settings related to SSO (Windows Logon). Those might have to do with observed behavior.
Yes SSO is in use and working properly.
That is not what I have asked for. Please post your Win7 64-bit machine object property settings (using EEM) that you have in "Windows Logon" section.
In the Windows logon section, all the checkboxes are selected:
Require Logon to Endpoint Encryption
Attempt automatic Windows logon
Require re-logon to Endpoint Encryption
Automatically logon as pre-boot user
Endpoint ENcryption logon component always active
Set Endpoint Encryption password to WIndows password
Must match Windows user name
