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

by

This works for me:

@echo OFF

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

FOR /F "usebackq skip=4 tokens=1-3" %%A IN (`REG QUERY %KEY_NAME% /v %VALUE_NAME% 2^>nul`) DO (
    set ValueName=%%A
    set ValueType=%%B
    set ValueValue=%%C
)

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

usebackq is needed since the command to REG QUERY uses double quotes.

skip=4 ignores all the output except for the line that has the value name, type and value, if it exists.

2^>nul prevents the error text from appearing. ^ is the escape character that lets you put the > in the for command.

When I run the script above as given, I get this output:

Value Name = DefaultColor
Value Type = REG_DWORD
Value Value = 0x0

If I change the value of VALUE_NAME to BogusValue then I get this:

"HKEY_CURRENT_USER\Software\Microsoft\Command Processor"\BogusValue not found.
