Delayed Start Script

About

Script to delay start of X processes and/or services by Y seconds.

Configuration

The script has a set of configurable parameters located in the top of the file. Setting these values should be enough to get it up and running.

set /a enable_evt_logging=1
set /a enable_cmd_tracing=1
set /a delay=60*5
set delayed_processes=explorer.exe notepad.exe
set delayed_services=MSSQL$SQLEXPRESS

If no processes or services are required set the variable to an empty value.

set delayed_processes=
set delayed_services=

Note: Logging to the Windows Event Log might require admin privileges.
