I just noticed I don't seem to have this installed on my x201 yet am using TPM and PW Manager. I this due to the Lenovo Enhanced Experience? I got my unit with W7 Pro 64 but upgraded to W7 64 Ultimate some time ago. Was an upgrade install. Was that a factor and somehow removed? Should I install it? What does it actually do in layman's terms? Thanks in advance.
