Run PowerShell ISE as System to Test scripts… From Software Center

by

Yet another post caused by my recent rebuilding of my lab from scratch after I totally hosed my last CM Server.  This time I’m documenting (blogging) a few additional things. So you write a lot of scripts for ConfigMgr?  Notice that they sometimes don’t perform quite as expected because they run as system instead of … Read more

Dynamic updates, what are those things?  Well, as Microsoft says “With Dynamic Update, if you start a computer from an existing operating system (for example, Windows 8), and then run Setup from that operating system [IN PLACE UPGRADE], Setup [Windows 10 Upgrade Setup] can check for new Setup files, including drivers and other files.”  You can enable it in your TS on the Upgrade OS step: (yes, you want to do this if you have bandwidth, way more info HERE, Thanks Adam)

Test Low Disk Space / Create Large Test File

by

So I stole this code from my friend Keith G, who provided it to assist with testing scenarios to see if our safe guards would work.
Basically, the 1 line command will check your drive, then create a dynamically sized file to leave “XX” GB remaining.  In my command, I leave only 15GB Free, which is low enough to trigger a failure on our in place upgrades.  Then I can test to make sure the the IPU TS fails the way I expect, running the proper remediation steps, and records the metrics for reporting.

Code: (run in elevated PowerShell Console)

get-volume c | % {$_.SizeRemaining - 15GB} |  % {Fsutil file createnew c:\TestFile.id $_}

So I made it into an App, I’ve added a few items into the app model to allow me to “install” it quickly on a machine to test failure scenarios.

App Code:

powershell.exe -command "get-volume c | % {$_.SizeRemaining - 15GB} |  % {Fsutil file createnew c:\TestFile.id $_}"
