We would like to know how are you defining that the scheduled volume optimization is not working?
It sets 2:00 AM as the default time for the task (you may change this if required). Once this time has passed, you should see an update or status of the run in the Intel® Optane™ application user interface. What does it say there if you check it at or after the scheduled time?
Following with this thread, the original issue is that the application Intel Optane doesn't work for some reasons and as suggested by you guys, I installed Intel® Rapid Storage Technology and now I can see the task in Task Scheduler however there is no trigger to tell when the task need to be executed. I can run it manually that's why I'm asking to know what should be the schedule for it so that I can setup it in Task Scheduler and as you mentioned, I will schedule it to run at 2AM everyday.
