I've finally got round to creating another in my 'Five Minute Mentor' series. The first in the series 'Deploying .exe applications in SCCM 2012' has been very popular so take a look here.
This time I've spent five minutes showing you how to quickly change your client settings priorities using a tool I created called the 'Update Client Settings Priority Tool'. This tool allows you to bulk change the priority quickly for client settings and SCEP settings.
You can download the tool from Technet Gallery via the Tools & Scripts menu.
I hope this helps you.
