[German] government experts warn, Windows 8 is an unacceptable security risk for governmental offices and companies. The so-called Trusted Computing might be a backdoor for NSA.
[..]
According to their [expert's] opinion the operating system contains a backdoor which cannot be closed. This backdoor is called Trusted Computing and might have the consequence that Microsoft could control every computer remotely. And therefore NSA could do it as well.
[..]
Three points are decisive: First the [new] TPM, in contrary to the existing standard, is active from the time when you switch on the computer. As soon as you start the computer you cannot decide anymore if you want Trusted-Computing (Opt-in). Secondly it is not possible to deactivate in future the TPM (Opt-out). Third the OS takes over the control over the TPM, in the case of Windows OS it means that the computer is controlled by Microsoft.

In the light of the current situation on spying, I have to say that I am happy that it goes in this direction.
