Why do you say that a system update was downloading via the Play Store?
Keep in mind that there can be various kinds of updates automatically downloaded by the system -- these can be Play Services updates, or Google Play security updates (which are separate from system updates), among other things.
I don't think you have to disable the Play Store or Download Manager. If you disable Download Manager, you'll have trouble downloading anything at all.
