Windows Screen Unlock Service

Case Introduction

To trigger the process automation of some RPA robots, you need to schedule cron jobs to execute business flows at different frequencies at the same time every day. If the computer screen is locked when the robot starts a process, a flow execution error is reported.

To resolve such issues, we provide a function that prevents screen lock to ensure operations of the RPA robot.
