Dear PI Geeks,
It's time to re-animate this community project since quite a while.
By chance I was just recognizing one of my virtual machines showing with CPU usage. Because this machine is running Windows Core (Microsoft Hyper-V Server 2012) high CPU usage is pretty uncommon. After logging on and launching task manager (type "taskmgr" in a command prompt), I identified TiWorker.exe as the responsible process. A quick internet research identified TiWorker.exe as the "Windows Modules Installer Worker". I concluded this process was just installing hotfixes but wanted to confirm this is the case by retrieving the list of installed hotfixes sorted by installation date:
Get-HotFix | Sort-Object -Property InstalledOn
