Windows TPM 2.0 Questions

[Boby]

Hi,

As Win 11 has TPM requirement and I'm not sure exactly how it works (and yes i used the search but i didn't fine answer to my questions) i have a couple of questions.

 

1. If i enable TPM module in the BIOS, but i don't use Bit-locker, does this change anything in Windows or it just covers the requirement without using it?

(for example will this lock my boot-loader and I'm unable to access this drive outside my machine or via other boot like USB?)

2. If i enable and use the TPM in the BIOS and i setup Bit-locker, will i be able to access my drive in case the motherboard or anything else die in the PC, or the windows itself get corrupted and i boot the PC using USB drive to recover some files from the drive?

 

3. Using TPM and Bit-locker, will i be still able to setup different boot OS on different drives, like for example Win 11 on C and Win 10 on D, Linux on G etc.

in essence, the TPM is nothing more than a piece of hardware that *can* be used by software to store authentication.

 

bitlocker uses it to unlock it's drive as long as no hardware has changed, outlook can use it as well (was surprised when i found this out...).

 

if you set up bitlocker, it'll ask you to make a backup of your recovery key, in case stuff breaks, you can use this key to access your drive again. no recovery key == no files. that's how bitlocker works.

 

as for dual-boot.. TPM changes nothing about the dumpster fire that trying to dual boot already is without taking windows 11 into account.
