The Automatic Updates detection frequency machine setting should be configured correctly. Specifies the hours that Windows will use to determine how long to wait before checking for available updates. The exact wait time is determined by using the hours specified here minus zero to twenty percent of the hours specified. For example, if this policy is used to specify a 20 hour detection frequency, then all clients to which this policy is applied will check for updates anywhere between 16 and 20 hours. If the status is set to Enabled, Windows will check for available updates at the specified interval. If the status is set to Disabled or Not Configured, Windows will check for available updates at the default interval of 22 hours. Fix: (1) GPO: Computer Configuration\Administrative Templates\Windows Components\Windows Update\Automatic Updates detection frequency (2) KEY: HKLM\Software\Policies\Microsoft\Windows\WindowsUpdate\AU\DetectionFrequencyEnabled
