This policy setting determines when policies that assign wireless network settings are updated. This policy setting affects all policies that use the wireless network component of Group Policy such as those in WindowsSettings -> Wireless Network Policies. It overrides customized settings that the program implementing the wireless network set when it was installed. If you enable this policy you can use the check boxes provided to change the options. If you disable this setting or do not configure it it has no effect on the system. The “Allow processing across a slow network connection” option updates the policies even when the update is being transmitted across a slow network connection such as a telephone line. Updates across slow connections can cause significant delays. The “Do not apply during periodic background processing” option prevents the system from updating affected policies in the background while the computer is in use. When background updates are disabled policy changes will not take effect until the next user logon or system restart. The “Process even if the Group Policy objects have not changed” option updates and reapplies the policies even if the policies have not changed. Many policy implementations specify that they are updated only when changed. However you might want to update unchanged policies such as reapplying a desired setting in case a user has changed it.
