I run Win 7 SP1 Ultimate 64 bit and recently downloaded IE10 from
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?
