How can I get the value of a registry key from within a batch script?

Question

I need to use a REG QUERY command to view the value of a key and set the result into a variable with this command:

FOR /F \"tokens=2* delims=    \" %%A IN (\         


        

Answer 1

@echo off
setlocal ENABLEEXTENSIONS
set KEY_NAME=HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\App Paths\awhost32.exe
set VALUE_NAME=Path
for /F "usebackq tokens=3" %%A IN (`reg query "%KEY_NAME%" /v "%VALUE_NAME%" 2^>nul ^| find "%VALUE_NAME%"`) do (
  echo %%A
)

How do you handle a space in the %%A variable? This results in C:\Program. The actual path is C:\Program Files\Symantec\pcAnywhere.

With regedit:

@echo off
setlocal
::if the scrit is not ran as administrator
::  and the key does not require admin permissions
set __COMPAT_LAYER=RunAsInvoker

set "key=%~1"
set "value=%~2"

regedit /e "#.reg" "%key%"


for /f "tokens=1,* delims==" %%a in ('find  """%value%""=" "#.reg"') do if "%%~b" neq "" echo %%~b
del /q #.reg

endlocal

Example:

call regreader.bat "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.0\Setup\1033\" Version

output:

3.0.30729.4926

Answer 3

Great level of solutions here.

My little grain of salt as the solution @Patrick Cuff did not work out of the box; I had 2 problems

• I use Windows 7 => changed to "skip=2"
• The value of the registry value had a space in it Value Value = C:\Program Files\...

Here is the solution I found: taking 4 tokens and setting ValueValue to %%C and %%D. (Thanks @Ivan!)

setlocal ENABLEEXTENSIONS
set KEY_NAME="HKEY_CURRENT_USER\Software\Microsoft\Command Processor"
set VALUE_NAME=DefaultColor

FOR /F "usebackq skip=2 tokens=1-4" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C %%D
)

if defined ValueName (
    @echo Value Name = %ValueName%
    @echo Value Type = %ValueType%
    @echo Value Value = %ValueValue%
) else (
    @echo "%KEY_NAME:"=%\%VALUE_NAME%" not found.
)

Answer 4

set regVar_LocalPrjPath="LocalPrjPath"
set regVar_Path="HKEY_CURRENT_USER\Software\xyz\KeyPath"

:: ### Retrieve VAR1 ###
FOR /F "skip=2 tokens=2,*" %%A IN ('reg.exe query %regVar_Path% /v %regVar_LocalPrjPath%') DO set "VAR1=%%B"

Thanks, i just need to use:

SETLOCAL EnableExtensions

And put a:

2^>nul

Into the REG QUERY called in the FOR command. Thanks a lot again! :)
