This is a quick and easy way to verify if a remote computer is running a 32-bit OS or a 64-bit OS.
If you have trouble getting it to work, be sure you're using an admin command prompt (I've seen wmic not work from a regular command prompt)
1. Open notepad.
2. Copy and paste below and save as OSscript.bat or whatever you want. Enjoy
:Start
cls
@echo off
Echo.
Echo Remote OS Info (Verifying 32-bit or 64-bit)
Echo.
Set /P Computer=Enter the Computer Name:
If "%Computer%"== "" goto BadName
pause
wmic /node:"%Computer%" os get osarchitecture
pause
Goto End
:BadName
Cls
Echo.
Echo You have entered an incorrect name or left this field blank
Echo Please enter a valid Name or press Ctr-C to exit.
Echo.
Pause
Goto Start
:End
