I have a test program installed on the server. The program needs to check and transfer the data to another control computer within 3 seconds, but at 00:00 on March 3, the data could not be transmitted once.

Inquiries about the task scheduler are as follows. 1. What exactly is the task registered in the task scheduler called SR (ex: registry backup) 2. Whether the SR can load the system and network 3. Problems that may occur when SR is changed to “Disable”
