TPM (Trusted Platform Module) enabled but the TPM-related info cannot be read

Hello everyone.

I had the same problem with a Windows 11 ARM.

Thanks to Pat-NS, I was able to solve my problem but, I also had to clear the TPM inside Windows by reverting to a snapshot with the tpm.msc.

Snapshots are so important in the VM world.

Hey NVM I figured it out the location. If anyone is having this issue deleting the NVRAM.DAT and NVRAM.TNVS Fixed the problem as discovered by @Pat-NS. The location of the files are in the folder your VMs are stored in. While in the folder find your VM and right click on it and select "Show Package Contents" you will see the two files there (NVRAM.DAT /NVRAM.TNVS). Just delete them or move them out. Then start your VM with TPM enabled and Windows should boot like normal with TPM.

Cheers!

Thank you ... this fixed my problem. Turning off Bitlocker in Windows 11, removing TPM in Parallels, deleting those files, adding back a TPM allowed me to turn on bit locker in Windows 11 again and all is well. Thank you.

No matter what I did (prior to the above) Parallels kept complaining about not being able to read the TPM related info ... until I deleted those 2 files (NVRAM.DAT and NVRAM.TNVS). THANK YOU.
