How to find out if a mchine is 32 bit or 64 bit

Hi All,

How to find out if a machine is 32 bit or 64 bit when it is switched on??
one way is to get the info from the manual.

hi,

can you try to run: dxdiag

the processor line will show you 64-bits if it is one.


NB. If it was an unix or linux machine, it would have been much easier to just run:

uname -a
or
getconf -a | grep KERN

revert

kind regards

Thank much for quick responses...

I tried the dxdiag command on both 32 bit and 64 bit machine...

U mean to say that, if the string "64" appears in the Process line then it is 64 bit otherwise it is 32 bit???

For example if the process reads as Intel(R) Celeron(R), I know its a 32 bit machine..but how will a Lehman find out? Probably he would look for the 32 bit string somewhere in the PC???

Is there any place in the machine which reads as 32 Bit?
