This is the solution provided by the Rogue Company Dev Team. Internal testing and a few real world tests seems to have proven to correct the issue.

Run powershell as an administrator then run the following code one line at a time (do not copy and paste the entire block into Powershell):
CertUtil -generateSSTFromWU $Env:TEMP\certs\RootStore.sst
$file=Get-ChildItem -Path $Env:TEMP\certs\Rootstore.sst
$file | Import-Certificate -CertStoreLocation Cert:\LocalMachine\Root
This creates a directory called “certs” under your Windows Partition (usually c:\) Users\<your username>\AppData\Local\Temp. The second line moves PowerShell into the new directory you just made. Next the script generates an SST file from Windows Update. The following command sets the variable “$file” with the SST you just created then it imports to the PC’s root certificate directory.
