Summarize this article in one sentence.
You can choose whatever password you want. It can be as long as you want too. Just remember to keep the quotation marks. The default will be .txt, so you’ll have to change this. If you’ve already saved the file just go to file, then save as, and then change the extension to .bat. You might need to check the box saying ‘show extension’ if you don’t see .txt. You can reach this tab from the Control Panel of your computer. Now go to Scheduled Tasks and navigate to the file that you just created. You can set it to run whenever you want it to – when someone tries to log on, when they try to open a certain file or folder, or any other prompt.

Summary:
Change "passwordhere" to the password of your choice. Save the file with an ending of .bat. Navigate to Performance and Maintenance.
