for more details i made some screenshot.

i got that problem since i've changed my mother board from 32-bit to 64-bit. so i got 64-bit windows but most of programs run on 32 bit.

The 32 bit shown in your first screen shot refers to the number of bits used to display color. 32 bit is the max.

Software that is associated with the display (Dxdiag) may be 32 bit based on the manufacturer even running on 64 bit systems. That is also normal.

Windows 64 bit has both a 64 bit and 32 bit programs, that is normal.
Many programs have only been written as 32 bit and run fine in Windows 64 bit.

The 32 bit software on your computer is what is required and available. All seems normal to me as far as I can tell.

Most software is still 32 bit. If a program has a 64 bit version, that version will usually be installed. There are some exceptions, such a Microsoft Office, that has both 64 and 32 bit versions available. Most people install the 32 bit version since it allows interfacing with more add-on programs than the 64 bit version.

There is nothing wrong with running 32 bit software on a 64 bit OS. Microsoft went to a great deal of trouble to make 64 bit Windows able to run 32 bit software. This is not an automatic ability of a 64 bit OS but something that must be designed in, and it isn't simple. There is a huge amount of 32 bit software out there and much of it will never be converted to 64 bit. This would require a lot of work by a developer and in many cases there is no significant advantage in doing so.

Microsoft Office is available in both 32 and 64 bit versions. But the 32 bit version is recommended for general use, even on a 64 bit OS. This is in the interests of better compatibility with third party software, much of which is 32 bit only. 32 bit browsers are usually recommended for the same reason.

64 bit software has some serious advantages, but only for some types of application. For the rest there is little or no advantage. Note that 64 bit applications usually consume more memory and will in some cases be slower. Not the usual case but it is possible.

Whether a program is 32 or 64 bit is a fundamental part of it's nature. A 32 bit application will not become 64 bit simply because it is running on a 64 bit OS.

Note that I am not talking about 32 bit vs 64 bit operating systems, That is another matter entirely and will not discuss it here.

i'm greatful for explaining my issue in great details. and i got 1 more questions.
am i able to change particular game from 32 bit to 64 bit? easy way. as it has some advanges on 64 bit
thanks.

am i able to change particular game from 32 bit to 64 bit?

Generally No.

Some programs will have the option to install either the 32 or 64 bit version. That is the only way. Internally 32 and 64 bit applications are VERY different and cannot be changed.
