PowerShell: Check if TPM Is Present
Need a quick yes/no check for whether a machine has a TPM chip - without digging through a full CIM output? This one-liner reads the status directly and clearly.
Prerequisites:

Quick Command:
Get-TpmExample Output:
TpmPresent : True

How It Works:
- Get-Tpm is a purpose-built cmdlet from the TrustedPlatformModule module - a simpler, more readable alternative to querying the raw Win32_Tpm CIM class directly.
- TpmPresent gives the direct yes/no answer to "does this machine have a TPM chip" - True or False.
- TpmReady and TpmEnabled show whether the chip is properly configured and turned on, not just physically present.
Pro Tip:
On some virtual machines (including certain Parallels configurations), this command can throw an error like A specified output buffer is too small due to how the virtual TPM is emulated - this is a VM-specific quirk, not an indication that something is wrong with your command.
