Hi guys,

My Windows10 installed the newest patch this week ,it's used for patch Intel CPU--Spectre&Meltdown vulnerabilities. But today when I test WindowsIntelPt project on this machine, I find it is something wrong in user mode trace. And everything is Okay before I installed the newest windows patch...
Log like this:

`Talos Intel PT Test Application
Version 0.5

Starting the Tracing and resuming the process...
Error!

All the dumps have been saved in "D:\mirror\transfer\Compiled_IntelPt\1746-01082018_Dumps".

I guess the problem is the newest windows used different CR3 between user mode and kernel mode.
