// I borrowed this great POC from Adam Chester [@_xpn_] to demonstrate spoofing for evading .NET 'Usage Logging'.
// This code will launch the target a suspended PowerShell.exe process, read PEB, update the ptr used to store environment variables, and resume the process
// Adam's original POC and blog for evading ETW with COMPlus_ETWEnabled can be found at these URLs:
