title: Signtool: Since Windows 10 Update 1803: No certificates were found that met all the given criteria
body: <p>I'm using signtool to sign my c# assemblies. Everything worked fine until Windows 10 1803 Update. Now as soon as a restart the Computer or even after suspending the Computer I get the error: No certificates were found that met all the given criteria.</p>
  
  <p>If I import the certificate again, everything works fine until the next restart...</p>
  
  <p>I tried to Import the certificate into different Folders of the Windows Certificate Store, i imported it for the current User or for Computer, I deleted it in all folders bevor the Reimport... but the Problem is always the same.</p>
  
  <p>Any hints would be great!</p>
