Something strange happened last night and I am trying to get to the bottom of it.
I have a Windows 10 In Place Upgrade collection - membership rule type is Direct
I have a remote site named HOP, which has a collection named "All HOP Computers". This collection has all workstation and servers, every device belonging to this site is in the collection.
IT personnel have been manually adding computers to the Windows 10 IPU collection for the win10 upgrade.
Last night, I had to redistribute the Win10 Upgrade package to HOP DP.
All of a sudden late in the night, ALL computers in HOP were getting the windows 10 upgrade.
While investigating what happened that triggered the mass upgrade, I found that somehow the All HOP Computers collection was added to the Windows 10 IPU membership as shown below.
Are there any ways I can find out how this collection made its way into the Win10 IPU collection?
Thank you so much!
