IE 10 32bit and 64bit

I run Win 7 SP1 Ultimate 64 bit and recently downloaded IE10 from
http://windows.microsoft.com/en-us/internet-explorer/downloads/ie-10/worldwide-languages.  
I was asked to chose my OS and I chose Win 7 SP1 64bit.
After installing  I noticed that iexplore.exe appeared in both Program Files and Program Files (x86).  That is no different than the situation with IE9.  But in Start|All Programs I only had Internet Explorer and it was the 64 bit version.  
So I guess MS is making the 64 bit version of IE10 the Default version for running on Win 7 64 bit.
I also seem to be able to run the 32 bit version of IE10 with no problems.  (That is the version of IE9  I ran on this Win 7 SP1 64 bit PC for some years.)
Any reason to run the 64 bit version of IE10 rather than the 32 bit version?

Yes, both versions are installed (and updated) by design by Microsoft.  You can use either version, but make sure you use the appropriate plugins (64 bit or 32 bit).  (I use 32 bit version as the default version).

aadih--Thanks for the prompt reply.  If you can, I would like a little elaboration on why MS chose the IE10 64 bit version as Default.
And when you say "plugins", I assume you mean Add-ons.  Most of those are carryovers from when I ran IE9 and so are 32 bit.  A few are 32 and 64 bit.

P.S. Java has always confused me about which bit version to download.  The Download page offers both 32 and 64 bit versions of Java according to Operating System, but the little paragraph right below the Download links implies the choice should be made according to Browser version.

Yes add-ons.

On my Windows 7 (64 bit) the ie10 32 bit  (preview) was automatically set as the deafult.. And if i wanted, I had to manually set ie10 64 bit as the default.  I do not know why Microsoft made ie10 64 bit as default now.

I use 32 bit Java version (but keep it disabled, however, until absolutely needed).  Hope it helps, somewhat.

Just for the heck of it, I ran IE10 iexplore.exe (which I assume is 32 bit) from Program Data (x86).  It brought up my Home Page just fine.  But when I checked Properties, it was the 64 bit version!!  (showing "C:\Program Files\Internet Explorer\iexplore.exe" as Target )
So I guess MS really wants the 64 bit OS to use the 64 bit IE 10.

Did you have the "Enhanced Protected Mode" turned on by any chance?

In my case, ie10 (32 bit or 64 bit) does not indicate the version in "About Internet Explorer."
The information is the same.

aadih--No, I do not have Enhanced Protected Mode turned on.

Now going back to my original post
"I also seem to be able to run the 32 bit version of IE10 with no problems.  (That is the version of IE9  I ran on this Win 7 SP1 64 bit PC for some years.)"

But now I realize that I was not running the 32 bit version of IE10, I was only starting IE10 64 bit from the iexplore.exe file in Program Files (x86).  So either the iexplore.exe file in both Program Data (x86) and Program Data is the same file (the size differs by only 5KB), or the file in Program Data (x86) redirects to the file in Program Data.

You are correct that the version of IE is not indicated in "About Internet Explorer".

Iexplore in program files (x86) is the ie 10 *32 bit* application.  Use it if you wish *not* to use the 64 bit version.
