How to get operating system 32bit or 64bit from a Windows Batch File (BAT File)

I have recently been preparing some custom install scripts lately and I found a few things that may prove to be of some use! This script uses a registry key to determine weather the host system is a 32bit or a 64bit system

Code Snippet

1. @echo off REM Hide output from commands
2. @echo Attempting to get operating system type (32bit or 64bit)...
3.  
4. REM -------------- Get 32bit or 64bit --------------
5. Set RegQry=HKLM\Hardware\Description\System\CentralProcessor\0
6. REG.exe Query %RegQry% > checkOS.txt
7. Find /i "x86" < CheckOS.txt > StringCheck.txt
8.  
9. If %ERRORLEVEL% == 0 (
10.     @echo This is 32 Bit Operating system!
11.     SET ostype = "32bit"
12. ) ELSE (
13.     @echo This is 64 Bit Operating System!
14.     SET ostype = "64bit"
15. )
16. del /s checkOS.txt >nul 2>&1 REM Clean up silently
17. del /s StringCheck.txt >nul 2>&1 REM Clean up silently
