*Purpose
 - UI Accessibility Checker
 - Verifies UI accessibility requirements

*LOLBIN Functionality/Steps
 1) Go to "Custom Verification Routines" link in reference section and copy the sample verification C# code into Visual Studio.
 2) Add proper assembly references (e.g. AccCheck.dll)
 3) Insert your C# code under a target method such as Execute()
 4) Compile to a .NET managed library (DLL)
 5) Invoke the code

// 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
