Bitlocker with Wintousb and in-use TPM chip

[spenol]

Hi all,

I have a laptop that I want to run a second version of Windows off a USB on occasions. However the laptop is already used with BitLocker - hence the TPM chip will be used to store the startup key for the main installation.

Can I also use bitlocker on the Wintousb Windows installation, and if so is it likely to reset the TPM configuration and thus cause problems for the main installation?

I note that Windows To Go doesn't use the TPM chip for this very reason, but I'm not sure if Winto usb will also work in the same way and thus could cause a problem for the main installation.

Thanks for any help.

Oliver.
