when running 64bit windows, open task manager goto process tab, there will be a list of 32 bit apps currently running...

Windows Vista Ultimate Edition x86 Oem
Microsoft Windows Vista Ultimate X64 OEM

which of this 2 is 64bit ?

[StyM]

the answer is already there... x64..

kani nga Windows Vista Ultimate Edition x86 Oem?para 32bit ni?unsa d i na X86?kay ingon man mo x64 is 64bit,ang x86?86bit pud?

hahaha lol..

[shogunfreak]

btaw...pero singit lng ko bro ha.... unsa man sad na bits na indicated sa ato video cards na ato gpalit..expensive raba... like for example: 256 mb/ 128 bit Nvidia Gforce.... nya sa xp..dli makita 128 bit gamit... libog jud ko mga bro.. can u enlighten me..

bits : width of path ( 16, 32, 64, 128,256, 288, 384, 512, etc )

ex. sdram 100 > 128mb/32bit - meaning 128mb ang capacity travelling in a 32bit width path from the north bridge AKA MCH to the processor

x86 : comes in 2 flavors -32 / 64

pentium4 : x86 ( denotes the architecture < 386,486, 586 blah blah )-32( bit )

Athlon64 : x86-64( bit )

x86 is the architecture of the CPU which i guess started way back from 8086 (8bit,16bit) MP ... again x86 architecture now comes with 32bit and the 64bit version ... but again back to your question ... a 64bit MP can actually run 32 bit apps and OS so basically Im not sure how to identify what Windows version is currently running ...

Sayun raman pag identify bro based from the OS installer like what vladimire said

Windows Vista Ultimate Edition x86 Oem
Microsoft Windows Vista Ultimate X64 OEM

Microsoft Windows Vista Ultimate X64 OEM -> This is the 64 bit OS version

Most applications that labeled x86 are mostly for 32bit machine generally for x86 architecture. Applications for 64 bit are identified using the attaached postfix "EM64" mostly. There are also postfix like IA64 which is intended only for Intel Itanium processors.

a 64bit MP can actually run 32 bit apps and OS so basically Im not sure how to identify what Windows version is currently running ...

In linux using the command "file <executable file>" will identify what type of executable the binary apps is. I don't know the equivalent in Windows.
Actually you can install 32 bit OS on 64 machines, but depending on OS installed, if you installed 32 bit OS on 64 bit machine, only applications binaries built for 32bit are compatible, 64bit apps won't work. But if you installed 64bit OS on 64 bit machine, only 64 bit applications will work.
