Windows – Find out if a PC has a TPM chip installed

bitlockerSecuritywindows xp

I have several Windows XP laptops that I need to check to see if they will work with Bitlocker if I install Windows 7. If they have a Trusted Platform Module (TPM) chip then Bitlocker should work without a USB key. If not, I'll leave them running XP.

Is there and easy way (or a free utility) that will tell me if a TPM is installed or integrated?

Update:
Windows XP lists the TPM (if present) in Device Manager under 'System Devices' (Windows 7 lists it under 'Security Devices').

I don't know if this works on Windows XP (it does on Vista) but from here there appears to be a Control Panel for it, at least on Vista. I'd hope the same is true for XP but I have no way to verify it.

Click Start, click All Programs, click Accessories, and then click Run.

Type tpm.msc in the Open box, and then press ENTER.

Doing this shows me this window.

tpm.msc

Otherwise as atroon advised it may show up in either the BIOS or Device Manager (detailed here)
