Windows - Command To Find Out If A Registry Path Exists Or Not
In Windows, you can use the reg query
command to find out if a registry path exists or not. Here's the command syntax:
shellreg query <RegistryKeyPath>
Replace <RegistryKeyPath>
with the full path to the registry key you want to check. For example, to check if the HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
key exists, you can use the following command:
shellreg query HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion
If the key exists, the command will display information about the key and its values. If the key does not exist, the command will display an error message stating that the key was not found.
You can also redirect the command's output to nul
to hide the output and only check the exit code. This allows you to perform conditional checks in batch scripts. For example:
shellreg query HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion > nul 2>&1
if %errorlevel% equ 0 (
echo Registry key exists
) else (
echo Registry key does not exist
)
In this example, if the registry key exists, the output will be "Registry key exists," and if the key does not exist, the output will be "Registry key does not exist."
