I installed my Windows 7 yesterday (64 bit version with a clean install) and I've noticed something strange.

I have two IE8 shortcuts in the start menu and when I looked further I see that one of them is 64 bit and the other is (x86). Why is this and do I need them both.

I also notoce that I seem to have two program file folders, one of which is called Program Files (x86) and the other is just Program Files. IE8 is in both of these folders.

Why are programs split between these folders.

One of them is 32bit IE (x86) and other is 64 bit version.
The 32bit version is provided because some IE addons (toolbars, plugins etc) are not compatible with 64 bit IE. In that case you can use 32bit IE, else use 64 bit IE.

Similarly, the Program Files(x86) is for 32bit programs (used when you install a 32 bit program), and other one for 64 bit software.
You will also find 2 system folders C:\Windows\System32 for 64 bit drivers and libraries. And C:\Windows\SysWOW64 for 32bit drivers etc.
In Registry also there are separate sections for many things for both 32bit and 64 bit programs.

The reason for this is because 64 bit Windows uses WOW system to run 32 bit programs and therefore MS thought it would be better to keep them separate.

an example of things that will NOT work in 64bit IE are flash items. You'll have to use 32bit ... or Firefox (which right now is only 32bit)
