How to determine if PC is x32 or x64

[Chocolate]

I have an old computer that I want to install a new Windows on it, I don’t have the user password to login.
Which tool/program can I use to find out what architect the computers processor is? (Hirens etc.)

(It’s highly unlikely to be 32 bit…)

In any place you can get a Windows command terminal (Recovery Environment, Hirens, or anything in between) you can run echo %PROCESSOR_ARCHITECTURE% to get the processor architecture.

@Knaper-Yaden will the environment variable show AMD64 even if the OS version is 32 bit?
edit: seems not… https://superuser.com/a/305902

Sure. That’s the actual processor architecture. For OS architecture you need to use something like wmic OS get OSArchitecture.

worked.

@Knaper-Yaden why don’t you try this simple experiment:
run

"C:\Windows\SysWOW64\cmd.exe" /c echo ^%processor_architecture^%

on a 64bit machine…

I rest my case.

In Hirens he can use SecurAble (https://www.grc.com/securable.htm) to check if the CPU is 64 bit.

I use https://sergeistrelec.ru, I saw in properties of my computer it shows the architecture besides the type running.
