Spark log-in starts when I turn on my PC

Is there a way where the Spark log-in pops up/starts when I want to actually turn it on? Right now, the log-in boxes pop up everytime I turn on my computer and I have to manually cancel it…Thanks for the info in advance!

Launch Spark, login, go to Spark > Preferences > Login - uncheck Launch on startup and press the Save button. Spark shouldn’t startup on you computer’s startup. But keep in mind, that you have to login once after you do a Spark upgrade, if you do this with the new version installer. Because the installer will add Launch on startup entry to your registry again and only when you login and Spark preferences are read, then it will remove that entry from the registry.
