Windows 7 - Require enhanced PIN at startup

I have encrypted my drive using TPM and read that using gpedit, there is an option to use an enhanced PIN at startup so that you can move away from just a numerical PIN and use letters and special characters.

The article I read said that not all systems support this and you may not know if your system does support it until you reboot and can't log back in.

Isn't there any kind of a test that can be performed to verify if this is a supported function or not on my pc?

Thank you

With this information in hand lets start to fill out the specs

System Manufacture/Model Number
As you see in my screen shot I have no listing due to my laptop being a custom build (I made it myself). For most people out there usually this will list a name brand like Dell and a model like 1525.
