Win7 IE10 64 vs 32

How can I tell for certain if I am using IE10 64 or 32 on Win7, now that they are combined!

I get a notice on the IE10 website that I am using 64 but the Enable Protected Mode is NOT checked!

Doesn't that mean I am using IE10 32??

Look at properties (right click) and see if the the program is located in "Program Files" of "Program Files(x86)". 64 bit or 32 bit.

It's in the Program Files... but again, the Enable Protected Mode (in both Security and Advanced) is not checked and my UAC is set for Never Ask (Off).

But there is another IE10 folder, with files, in the Program Files (x86), which I assume is 32.

Maybe MS is as confused as I am?

What is in Program Files is 64 bit IE.
What is in Program Files(x86) is 32 bit IE.

Where is the confusion? ;-)

It is confusing.  When you install IE10 it installs iexplore.exe in both Program Files and Program Files (x86).  And they both have the same version number.  The size is also almost the same.  No where does it mention 64 bit or 32 bit.
However if you go to C:\Users\Username\AppData\Roaming\Microsoft\Windows\Start Menu\Programs you will find a shortcut to IE.  If you right click on that and then Open File Location, you will be taken to either the Program Files or Program Files (x86) folder.  The former means the iexplore.exe file being used by Windows is 64 bit.  If you go to Program Files (x86) it means you are using the 32 bit version.
Windows apparently picks the bit version according to the bit version of Windows.

Or, when running, determine from task manager .

Here is a small correction to my earlier post.  
The statement "Windows apparently picks the bit version according to the bit version of Windows"  is probably not correct.
IE10 can run either the 32 bit or the 64 bit versions.  You can determine which is running when you start IE by following the steps mentioned earlier.  Or you can right click on the shortcut you are using to start and then right click again on "Internet Explorer" in in the drop down menu.  Now you can click Properties and in the Target line on the Shortcut tab you will see which iexplore.exe is being used. ( Program Files or  Program Files (x86) ) But this is just for Start up.  It seems IE can open the other when it wants to, but I do not know why that is.

You said "I get a notice on the IE10 website that I am using 64 but the Enable Protected Mode is NOT checked!"
Which website is this?  And why do you think that Enable Protected Mode not being checked means you are running 32 bit.

I had read on an MS IE10 site that the Protected Mode was the 64 bit version.

Also advised that I was running 64.

I have also noticed that Task Manager shows that when I run either of my IE10s, from Program Files or 86 Program Files, that I am running 32!

Go figure!

Well, that could certainly be.  Did you go through the suggestion I made earlier.

"Or you can right click on the shortcut you are using to start IE and then right click again on "Internet Explorer" in in the drop down menu.  Now you can click Properties and in the Target line on the Shortcut tab you will see which iexplore.exe is being used.

In Task Manager, on the Processes tab... you will see at least 2 instances of iexplore.exe running. By default, 64 bit versions of windows running IE 10 will start a 64-bit window containing a 32-bit tab. That will be indicated by
iexplore.exe
iexplore.exe *32

Every tab you open in that same window after that will start another
iexplore.exe *32
process. If you open another window, it will start another
iexplore.exe and another
iexplore.exe *32
process (one for the window, and another 32-bit tab process).

If you explicitly start \Program Files (x86)\Internet Explorer\iexplore.exe then you will see 2
iexplore.exe *32
processes... 1 for the window and 1 for the tab.

If you want to run 64-bit windows AND 64-bit tabs, you have to check the boxes next to Enable Protected Mode (requires restarting Internet Explorer) on the Security tab, AND next to the Enable Enhanced Protected Mode* option under Security on the Advanced tab. Like soIE10 - Internet Options - Security - Protected Mode (click for larger)IE10 - Internet Options - Advanced - Security - Protected Mode (click for larger)Then reboot and you should no longer see any
iexplore.exe *32
processes. e.gTask Manager - 64-bit IE10 Processes (click for larger)

Thanks Darr... actually I was trying to stay with the 32 bit. I've got a program that doesn't run with 64... yet!

Also, when Protected Mode got checked after reinstalling IE10 several months ago I found that Outlook would not open sites in the reading pane!

It should work by default then, since 32-bit tabs are used in the 64-bit window (that enables 32-bit plugins and add-ons to all function, too... that's why they did it like that by default).

There should be a setting in Outlook to adjust how the IE security integration works, but where it is and what setting to change depends on what version of Outlook it is. In Outlook 2007 it's in Tools->Trust Center... in 2003 all you had to do was right-click the blocked items and different ways to override it were right in that version's context menu. I haven't tried changing it in Outlook 2010.
