We have a Windows server 2012 R2 that we are using to virtualize a Windows 2008 R2 server via Hyper-V.
In the users RDP sessions I have noticed that they are running both the 32 and 64 bit version of IE. I have been told that to optimize performance and to take advantage of the multiple threads of our hexacore processors, we should only run the 64-bit version. However when I tested running both versions, regardless of the version I launch, I noticed in the task manager that sometimes it loads as the 32-bit version and sometimes it loads as the 64-bit version even if I launch it from the same shortcut.
Does anyone have any ideas if this is controllable or is it due to perhaps some applications/processes requiring the 32-bit version of IE?
