Is there a way to use a batch file to check if a registry value exists?

yes use the reg command. it will give error if the key you specified is not in the registry. You can catch this error in your batch file.

Ok, I made this batch file: ~~~~~~~RegTest.bat REG Query HKLM\Software\Microsoft\Windows\CurrentVersion\Run /v BLAH > nul IF %ErrorLevel%==1 GOTO Failed IF %ErrorLevel%==0 GOTO Success ~~~~~~~RegTest.bat If the value "BLAH" doesnt exist, the file displays the phrase, "Error: The system was unable to find the specified registry key or value". Is there any way to test to see if a value exists without displaying an error message if it doesnt exist?

I never heard of the "reg command", but in general commands write errors to stderr which can not be easily redirected. Results which go to stdout can readily be redirected: somecomd > nul If at first you don't succeed, you're about average. M2

try this REG Query HKLM\Software\Microsoft\Windows\CurrentVersion\Run /v BLAH > nul 2>&1

ghostdog, cool If at first you don't succeed, you're about average. M2
