Answer 1

Wmic can be a weird beast. This works here in Windows 8 32 bit.

The extra code is needed to remove the trailing Carriage Return.

@echo off
setlocal enabledelayedexpansion
(For /F "tokens=1,* delims==" %%A in ('"wmic OS get FreePhysicalMemory,TotalVisibleMemorySize /value |find "M" "') do (
set "line=%%A= %%B"
set "line=!line:~0,-1!"
echo !line!
))>output.txt

First you would consider to convert the WMIC output encoding from Unicode to ANSI to ommit unicode characters (like empty Echoes), a simple trick to do this is filtering the output with FIND/FINDSTR command(s), after applying the output filter you just need to read the output with FOR /F to split the string using the desired tokens value and delims delimitter.

Here is the code:

@Echo OFF

(For /F "Tokens=1,* Delims==" %%A in (
    'wmic OS get FreePhysicalMemory^,TotalVisibleMemorySize /Format:list ^| FINDSTR "[0-9]"'
)DO (
    Echo %%A= %%B
))>"File.txt"
