Here is my solution:
$IEProcess = [System.Diagnostics.Process]::Start("iexplore", "-noframemerging")
Sleep -Seconds 1
$ie = $(New-Object -ComObject "Shell.Application").Windows() | ? {$_.HWND -eq $IEProcess.MainWindowHandle}
I launch an instance with the System.Diagnostic.Process library, I was using Start-Process but getting some weird outcomes, this fixed that right up. At this point I have an instance of IE open with the noframemerging switch and a variable pointing the process.
I threw a sleep in there to give the com object a chance to construct before trying to reference it.
Then I grab all the windows com objects and select the one that has a handle (HWND) that is the same as the one from the process I just started and assign it to my $ie variable.
The end result is I have a variable that references a com object of Internet Explorer that is independent of all other sessions. The reason I needed this in particular is I'm opening many instances of IE and logging into a website with different user accounts, if they share a session the login page is skipped and they will already be logged in as the first user that logged in.
Thanks for all the help guys!
