Aplica-se a: Windows 8.1 EnterpriseWindows 8.1 ProWindows RT 8.1

This article describes an issue when you use the Certutil.exe command-line tool. A hotfix is available to resolve this issue. The hotfix has a prerequisite.


Assume that you copy a .pfx certificate file to a Windows 8.1-based or Windows Server 2012 R2-based computer that has its Trusted Platform Module (TPM) chip enabled. You run the certutil -importpfx command and the -pin argument to import the .pfx file together with a virtual smart card (VSC) personal identification number (PIN). In this situation, the -pin argument cannot be recognized, and you are always prompted for the VSC PIN.


This issue occurs because the value for the -pin argument is saved into a global variable during the argument processing. However, the value is never used by the Certutil.exe command-line tool. Therefore, you are always prompted for the VSC PIN.


To resolve the issue, install the hotfix that is described in this article.
