Recently I discovered a really annoyoing issue when:
Error message: ZTIWindowsupdate has run And Failed too Many Times. Microsoft – Printer 6/21/2006 12:00:00 AM 10.0.15063.0
Deploying with MDT
NO WSUS
Both Windows 10 1703 and Windows 10 1709

Here´s the issue, when running the Windows update step in the MDT, it hangs on some Updates

Biggest question, What it is?
Its two drivers,
Microsoft to PDF
XPS Services

And somehow it causes the Windowsupdate to retry,retry and retry. Its simpely cant succeed. These updates are not in the WSUS just when you going to microsoft.com

My solution is to “Disable” the feature before the updates, and “Enable” them after the updates. Because it bad drivers from Microsoft.

The solution:
1. First, Open the Task Sequence that you are deploying.

2. Add a Step into the task sequence. (Make sure you add it After Windows is Installed, Add it just before Windows update is running.)
Add\Roles\Uninstall Roles and Features

3. Check Microsoft Print to PDF

4. Check XPS Services

5. Then We add a new step in the task sequence. Pretty down in the task sequence. Just before “Apply Local GPO Package”
Add\Roles\Install Roles and Features

6. Check Microsoft Print to PDF

7. Check XPS Services

8. Then apply

9. Update your Deploymentshare and try again. On my machine it solved the issue. Good luck!
