The IsWindowAvailableNow WMI class method, in Configuration Manager, determines whether a service window of a specified type and the given duration is available to run at the point of time when the call is made.

The following syntax is simplified from Managed Object Format (MOF) code and defines the method.

uint32 IsWindowAvailableNow(
	 [IN]  UInt32 ServiceWindowType,
	 [IN]  Boolean FallbackToAllProgramsWindow,
	 [IN]  UInt32 MaxRuntime,
	 [OUT] Boolean CanProgramRunNow
);

Parameters

ServiceWindowType

Data type: UInt32Qualifiers: [in]Type of service window. The following table lists possible values.

Value Service Window Type Description

1

ALLPROGRAM_SERVICEWINDOW

All Programs Service Window

2

PROGRAM_SERVICEWINDOW

Program Service Window

3

REBOOTREQUIRED_SERVICEWINDOW

Reboot Required Service Window

4

SOFTWAREUPDATE_SERVICEWINDOW

Software Update Service Window

5

OSD_SERVICEWINDOW

OSD Service Window

6

USER_DEFINED_SERVICE_WINDOW

Corresponds to non-working hours.
FallbackToAllProgramsWindow

Data type: BooleanQualifiers: [in]true, if the generic All programs window service window is to be used when a window specified in FallbackToAllProgramsWindow is not available; otherwise, false.
MaxRuntime

Data type: UInt32Qualifiers: [in] Maximum run time, in minutes, that a software update installation has to complete before the installation is no longer monitored by Configuration Manager. This setting is also used to determine whether there is enough time to install the update before the end of a maintenance window. The default setting is 60 minutes for service packs and 5 minutes for all other software update types. Values can range from 5 to 9999 minutes.
Important
Make sure that the maximum run time value is not set for more time than the configured maintenance window or the software update installation will not initiate.
CanProgramRunNow

Data type: BooleanQualifiers: [out] true if a service window of the specified type and the given duration is available to run at the point of time when the call is made; otherwise, false.

Return Values

A UInt32 data type that is 0 to indicate success or nonzero to indicate failure.
