Launch ClientFaux and click to the Configure CM tab and provide your CM Server FQDN and three letter Site code.
Then click to the Device Naming page and provide your desired naming pattern and starting and ending numbers.
You can also increase the number of threads (I’ve tested up to 12 threads and seven is a good happy medium for resource usage, but feel free to go crazy).
Then to see it in action…click to the ‘Ready’ page and hit ‘Ready!’ and away we go!
The Big Warning
This is designed for DEMO or TestLab CM instances. I do not recommend running it against your Production CM instance as it can create thousands and thousands of CM clients if left running for a few hours! This can be hard to filter out of data for reporting, dashboards and the like.
Recently at work, we had a task come up which saw us needing to move tens of thousands of devices between collections in CM. We decided to run some tests to find the fastest way! We compared:
The SCCM 1511 Era Collection Cmdlets
The newly released speedier Collection Cmdlets which shipped with Tech Preview 1803
Using Keith Garner’s super powerful CMPSLib Module
Query Based Membership
AD Group Query Membership
Direct SQL Membership Tampering ☠
I’d always kind of wondered myself, so it was a fun challenge to come up with some hard numbers. And for the last item in the list…this is just for fun, I do not recommend using this in your production…or your testlab. Or anywhere.
The test lab
All testing occurred in my VM Testlab, a Ryzen 7 1700 with 64 GB of RAM, with storage served on NVMe m.2 SSD drives. A beastly machine (also hello to viewers from the year 2025 where we have 6TBs of storage on our phones and this is laughably quaint. Here in 2018, we believed more RBG = more better, and we were happy, damn it!) Continue reading →
I’ve performed a number of Windows 10 Deployment projects, and have compiled this handy list of must-have customizations that I deploy at build time using SCCM, or that I bake into the image when capturing it.
Hope it helps, and I’ll keep updating it as I find more good things to tweak.
With the Advent of client activity indicators in SCCM 1606:
We can now see which machines are online at a given time. I love these green checkboxes.
I thought it would be cool to try to make a collection of only currently online machines. So, into the query editor we go! We’ll add a new query rule, and then use the wizard to add a new value. This is all that you need to grab only the currently online systems.
This collection works VERY well for Incremental Updates. However, Scheduled Updates don’t make much sense
