Enabling Adobe Acrobat Reader DC to trust the Windows Certificate Store / Certificates (Local Computer)

I recently had a client who used my previous post:

Digitally signing Adobe Acrobat PDF documents with Microsoft Certificate Authority Certificates
http://terenceluk.blogspot.com/2013/09/digitally-signing-adobe-acrobat-pdf.html

… to allow users to sign Adobe PDF documents with user certificates generated by an internal trusted Microsoft Certificate Authority.  During the time when I wrote the blog post above, I was unable to find a way to enable the version of Adobe Acrobat or Adobe Reader to trust the Windows Certificate Store (Certificates (Local Computer) so I provided a not as efficient workaround that isn’t very efficient.  Having to revisit this issue again recently with the client, it looks like Adobe Reader DC now provides enabling the application to trust the Windows Certificate Store / Certificates (Local Computer).  The following is where this setting is located:

Edit > Preferences:

Signatures > Verification – Control how and when signatures are verified > More…

In the Signature Verification Preferences window, locate the Windows Integration section where the Trust ALL root certificates in the Windows Certificate Store for: Validating Signatures is found:

Enable the following 2 configuration settings:

• Validating Signatures
• Validating Certified Documents

Adobe Acrobat Reader DC should now trust all of the root and intermediate certificate authorities found in the Windows Certificate Store / Certificates (Local Computer)
