Query Registry Key and add to a system variable or Text file (Batch file)

Hi all 

I'd like to query the Key / Value:  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\DefaultUserName and add the output to a System Variable (%VariableName%)  



Thx 4 hlp! 

Can you modify the registry key using the batch file?

Hi Tom2011,
 
Here's an example:
 
@ECHO OFF
:: delims is a TAB followed by a space
FOR /F "tokens=3 delims=  " %%A IN ('REG QUERY "HKCU\Control Panel\International" /v sCountry') DO SET Country=%%A
ECHO Country=%Country%
SETX Country %Country%
 
Also have a look at the SETX command itself, depending on what registry value you are looking for you can do it directly with SETX.
 
SETX TZONE /K HKEY_LOCAL_MACHINE\System\CurrentControlSet\    Control\TimeZoneInformation\StandardName
 
Hope this helps
