TPM update: TPM owned > please clear...


Recommended Posts

A recommended update for tpm available.
But... owned \ clear is out of my field of experience :O)
 

What can happen if it's cleared, f.ex. am unsure about interaction with bitlocker partitions.
And should it be re-owned (whatever that is) afterwards ? Big mysteries...

Thanks for any info.

Suspend BitLocker. Disable the TPM device in Device Manager. Reboot to BIOS setup. Clear the TPM. (You check the box in BIOS setup but it won’t prompt to clear until you boot up normally.) Boot back to Windows and try to update the TPM. I’m not sure if you have to enable the TPM device in device manager first, but only do it if it makes you, because Windows might “claim” it right away.

 

If it works, enable the TPM device and then resume BitLocker and you should be all set. Have your BitLocker recovery keys handy just in case.

Thanks, a good overview which pointed me towards more reading (found good Dell pages about just this), and will go ahead when feeling well prepared.
