Answer 1

You should escape | by ^| when you use it inside the for command

Commandline :

@FOR /F "usebackq" %a IN (`wmic MEMORYCHIP get Capacity ^| findstr [0-9]`) DO echo %a

Batch File :

@echo off
@FOR /F "usebackq" %%a IN (`wmic MEMORYCHIP get Capacity ^| findstr [0-9]`) DO Set "Memory=%%a"
    echo %Memory%
pause
