Update that enables user to set Application Pool to run as Null Virtual Account in Windows 8.1 or Windows Server 2012 R2

About this update

When an Internet Information Services (IIS) worker process that's running with ApplicationPoolIdentity tries to access an external resource, for example, content on a UNC Share, the logon session will show the machine identity instead of IIS APPPOOL\ApplicationPoolName because the ApplicationPoolIdentity by nature is the Local Machine Virtual Account identity.

This update allows you to disable the local machine account from the remote logon session for ApplicationPoolIdentity by setting the password to the Null Virtual Account password, and then IIS will use this Null Virtual Account to access the external resource.
