Drive Encryption For HP Protect Tools?

My flat mate set up a security thing called Drive Encryption for HP ProtectTools. What this does is, upon start up, before it lets you load windows, you need to enter a password and pin. Clearly, it is anoying, so he handed it to me to get rid of it. It will not uninstall, as it says it is still active, and must be deactivated. I went into services - found it - disabled it. I went into some .msc thing i saw on the HP forums, disabled it. I went into the BIOS - Disabled it. I have disabled every aspect of it, however, it will still not uninstall, and continues to ask for a password and pin prior to windows starting.
