The Parallels Toolbox auto-updater has no defer option, like "Remind me tomorrow" or similar, and the update cannot be cancelled. For security reasons, we are starting to downgrade primary Mac user accounts to standard users, and having a separate admin account. Standard users don't always have access to the admin credentials (also for security reasons) so there is no way to dismiss the upgrade. Toolbox is hugely useful, but if we can't manage the updates, then we may have to uninstall for these users.
