BleepingComputer.com: HOW TO CHECK SYSTEM X32 OR X64?

I AM USING WINDOWS XP, SO HOW TO CHECK WHETHER MY SYSTEM IS RUNNING WITH X32 OR X64?

In Windows XP x64 edition :
1. When you start PC, the boot logo shows x64 edition under Windows XP
2. Right-click on My Computer icon on desktop and select Properties. Under the General tab in System Properties you would see x64 Edition
3. Open Start Menu > Run, type winver and press Enter. You would see x64 edition in the Windows LOGO image.
4. In Windows x64, there are two Program Files folders one is C:\Program Files and other C:\Program Files(x86). Latter for 32bit programs.
5. In Windows x64, there are two System folders. One is C:\Windows\System32 and other C:\Windows\SysWOW64. Latter for 32bit programs and drivers.

None of these are true for Windows XP 32bit (also called x86) version.

Before you go inspecting your Windows version, first have a look at your CPU whether it is 32bit or 64bit. Windows XP x64 can only be installed if you have 64 bit CPU processor. This is also true for any other 64bit OS, like 64bit Linux.

Here is another method for XP and Vista:

http://support.microsoft.com/kb/827218

The article says to run winmsd, but I always use msinfo32 these days. You can get a lot of information about a system with minimal questions via a copy/paste the information operation. It will tell you your processor (hardware) type, motherboard, BIOS, etc.

The winmsd.exe was replaced with msinfo32.exe a while ago under some systems, so if winmsd.exe will not run on the system, use msinfo32.exe instead.

thanks for reply ROMEO 29,

To know if you have 32bit CPU or 64bit CPU :

1. Download CPU-Z from here : http://www.cpuid.com/download/cpuz/cpuz_152.zip.
2. Extract and run cpuz.exe.
3. Look in the box labeled Instructions. Along with other things like MMX, SSE etc, you would find x86 or x86-64. If its only x86, then you have 32bit CPU. If its x86-64, then you have 64bit CPU.
