Is there a way I can run a batch file upon locking my computer, and then run another batch file when I unlock it? (Windows 8.1)
Thank you!
I am sorry I can't give you english screenshots.
Just create a task in planned tasks.
At the "trigger" tab, you can select "At lock" and "At unlock".
As user294496 pointed out, one of the fastest ways to do this would be to set a "Scheduled Task" up to execute your batch files at lock/unlock.
Another option would be to take a look here and see if this little GUI tool that somebody wrote for something similar might be a better option for you if you don't want to do this using scheduled tasks. If you are interested in writing some C#, I'll bet it wouldn't be too difficult to write a utility similar to this.
