This answer already is there but I don't want to do it with Task scheduler as it reduces my machine efficiency.

Answer 1

Windows has a "Task Scheduler", which is what you need to use to run a program on a recurring schedule and/or on machine startup.

Answer 2

You can program a task, or make an executable with your jar and place it on startup folder if windows 7 or lower

PROGRAM A TASK (SOURCE)

To Run Task Scheduler using the Windows interface

• Click the Start button.
• Click Control Panel .
• Click System and Maintenance .
• Click Administrative Tools .
• Double-click Task Scheduler .

To Run Task Scheduler from the Command Line

• Open a command prompt. (cmd or click Start, All Programs, Accessories, Command Prompt)
• At the command prompt, type Taskschd.msc.

STARTUP FOLDER (SOURCE:)

On Windows 7 and earlier versions of Windows, the Start menu contained a “Startup” folder to make this easy. On these versions of Windows, you can simply open your Start menu, locate a shortcut to an application you want to start automatically, right-click it, and select Copy. Next, locate the Startup folder under All Apps in the Start menu, right-click it, and select Paste to paste a copy of that shortcut.

Answer 3

Create a bat file for that you want to achieve and schedule the windows Task Scheduler as listed below.

1. Click Start
2. Type Task and then click Task Scheduler

Once the Task Scheduler is open, you can create your own custom task by clicking Create Basic Task. This action starts a wizard that walks you through the process, prompting you with what program you want to execute, as well as how often and what time it should be run.
