Quicken runs slowly, and it makes all the other programs running at same time run slowly.
This problem persists even after I exit Quicken until I reboot. Does anyone else have this problem. I run Quicken Premier 2019

If you haven't already, I suggest you use Windows Task Manager (press Ctrl + Shift + Esc) to determine if Quicken is consuming CPU resources or increasing memory while idle.  If so, you may have a runaway reminder (aka a corrupt reminder). Unless you can identify the specific reminder, I suggest you delete all of the reminders, perform a Copy and Validate, and reenter your reminders.

Always save a backup (press Ctrl + B) before making any significant changes to your data file.
