I am relatively new to Windows 10. This morning my computer seemed ever so slightly slower than it had been. In looking at the task manager the memory usage was at 30% which is higher than usual. The major contributor is MoUSO Core Worker Process at 2219.2 MB and it is quiescent whenever I check. Should it always reside in memory just waiting to occasionally spring into action or does its continual presence indicate that there is a problem? I ask because this seems to be a departure from how my system had been operating.
