Fun scripts in cmd

In this post, I’ll represent temporary parameter by using %name of parameter%, you need to change the whole thing with your parameter. Please take a look at the example below. The reason I use %name of parameter% because it represent a variable in batch file.

simpleBatch.bat (run as administrator)

@echo off
setlocal
set username=olaf
REM create new user
net user %username% /add
net user
pause
Result:

Administrator	DefaultAccount	Guest
xxx	olaf	xxx

sc config %service name% start=auto
net start %service name%

Ex (remember to change %service name% to service name you want to enable):

sc config RemoteRegistry start=auto
net start RemoteRegistry

Find particular service in cmd

sc query type=service state=all | findstr /i “remote”
/i: case insensitive
