I just found this:

"Opt into the extended Auto-update policy
The extended Auto-update policy is available in the Admin console. To set the policy, do the following:

Sign in to your Google Admin console.
Sign in using an administrator account, not your current account sxxxxxxxxxxxx@gmail.com

In the Admin console, go to Menu and then Devicesand thenChromeand thenSettingsand thenDevice settings.
To apply the setting to all devices, leave the top organizational unit selected. Otherwise, select a child organizational unit.
Go to Device update settings.
Click Extended Auto-update.
From the list, select Allow updates during extended auto-update period.
Click Save."

How OR where do I find what my ADMINISTRATOR ACCT. sign in is???!!!
