To enhance system performance, it is recommended that one minimize startup programs/files/services loading. Accordingly, I unchecked (deactivated) all three Acronis TI related startup files: Acronis Scheduler2 Service, Acronis Timounter Monitor and TrueImageMonitor.exe (see .gif below). I learned the hard way that Scheduler2 Service is necessary to avoid the dreaded "Error #1722: The RPC server is unavailable" error. So I reactivated it. Why are Timounter Monitor and TrueImageMonitor.exe still necessary? Thanks in advance.
