Reference
Win32_OperatingSystem class
The Win32_OperatingSystem WMI class represents a Windows-based operating system installed on a computer. Any operating system that can be installed on a computer that can run a Windows-based operating system is a descendent or member of this class. Win32_OperatingSystem is a singleton class. To get the single instance, use “@” for the key.
Windows Server 2003 and Windows XP: If a computer has multiple operating systems installed, this class only returns an instance for the currently active operating system.
The following syntax is simplified from Managed Object Format (MOF) code and includes all of the inherited properties. Properties and methods are in alphabetic order, not MOF order.

Data execution prevention is a hardware feature to prevent buffer overrun attacks by stopping the execution of code on data-type memory pages. If True, then this feature is available. On 64-bit computers, the data execution prevention feature is configured in the BCD store and the properties in Win32_OperatingSystem are set accordingly.

Windows Server 2003 and Windows XP:  This property is not available.

DataExecutionPrevention_Drivers
Data type: boolean
Access type: Read-only

 

When the data execution prevention hardware feature is available, this property indicates that the feature is set to work for drivers if True. On 64-bit computers, the data execution prevention feature is configured in the BCD store and the properties in Win32_OperatingSystem are set accordingly.

Windows Server 2003 and Windows XP:  This property is not available.

DataExecutionPrevention_SupportPolicy
Data type: uint8
Access type: Read-only

Windows Server 2003 and Windows XP:  This property is not available.

 

The following table lists the possible values.

Value Meaning

Always Off
0
 DEP is turned off for all 32-bit applications on the computer with no exceptions. This setting is not available for the user interface.

Always On
1
 DEP is enabled for all 32-bit applications on the computer. This setting is not available for the user interface.

Opt In
2
 DEP is enabled for a limited number of binaries, the kernel, and all Windows-based services. However, it is off by default for all 32-bit applications. A user or administrator must explicitly choose either the AlwaysOn or the OptOut setting before DEP can be applied to 32-bit applications.

Opt Out
3
 DEP is enabled by default for all 32-bit applications. A user or administrator can explicitly remove support for a 32-bit application by adding the application to an exceptions list.

 

Debug
Data type: boolean
Access type: Read-only

 

Operating system is a checked (debug) build. If True, the debugging version of User.exe is installed. Checked builds provide error checking, argument verification, and system debugging code. Additional code in a checked binary generates a kernel debugger error message and breaks into the debugger. This helps immediately determine the cause and location of the error. Performance may be affected in a checked build due to the additional code that is executed.

Description
Data type: string
Access type: Read/write

 

Description of the Windows operating system. Some user interfaces for example, those that allow editing of this description, limit its length to 48 characters.

Distributed
Data type: boolean
Access type: Read-only

 

If True, the operating system is distributed across several computer system nodes. If so, these nodes should be grouped as a cluster.

EncryptionLevel
Data type: uint32
Access type: Read-only

 

Windows Server 2003 and Windows XP:  Encryption level for secure transactions: 40-bit, 128-bit, or n-bit.

ForegroundApplicationBoost
Data type: uint8
Access type: Read/write

 

Increase in priority is given to the foreground application. Application boost is implemented by giving an application more execution time slices (quantum lengths). A ForegroundApplicationBoost value of 0 (zero) indicates the system boosts the quantum length by 6; if 1, then 12; and if 2 then 18. The default value is 2.

Access type: Read-only

 

Additional description for the current operating system version.

Windows Server 2003 R2:  Contains the string “R2”.

Windows Server 2003 and Windows XP:  OtherTypeDescription is null.

PAEEnabled
Data type: Boolean
Access type: Read-only

 

If True, the physical address extensions (PAE) are enabled by the operating system running on Intel processors. PAE allows applications to address more than 4 GB of physical memory. When PAE is enabled, the operating system uses three-level linear address translation rather than two-level. Providing more physical memory to an application reduces the need to swap memory to the page file and increases performance. To enable, PAE, use the “/PAE” switch in the Boot.ini file. For more information about the Physical Address Extension feature, see http://go.microsoft.com/fwlink?LinkID=45912.

Windows XP:  The PAEEnabled property is not available.

ServicePackMinorVersion
Data type: uint16
Access type: Read-only

 

Minor version number of the service pack installed on the computer system. If no service pack has been installed, the value is 0 (zero).

SizeStoredInPagingFiles
Data type: uint64
Access type: Read-only

 

Total number of kilobytes that can be stored in the operating system paging files—0 (zero) indicates that there are no paging files. Be aware that this number does not represent the actual physical size of the paging file on disk.

For more information about using uint64 values in scripts, see Scripting in WMI.

Status
Data type: string
Access type: Read-only

 

Current status of the object. Various operational and nonoperational statuses can be defined. Operational statuses include: “OK”, “Degraded”, and “Pred Fail” (an element, such as a SMART-enabled hard disk drive may function properly, but predicts a failure in the near future). Nonoperational statuses include: “Error”, “Starting”, “Stopping”, and “Service”. The Service status applies to administrative work, such as mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is online, but the managed element is neither “OK” nor in one of the other states.

 

The values are:

“OK”

“Error”

“Degraded”

“Unknown”

“Pred Fail”

“Starting”

“Stopping”

“Service”
SuiteMask

TotalSwapSpaceSize
Data type: uint64
Access type: Read-only

 

Total swap space in kilobytes. This value may be NULL (unspecified) if the swap space is not distinguished from page files. However, some operating systems distinguish these concepts. For example, in UNIX, whole processes can be swapped out when the free page list falls and remains below a specified amount.

For more information about using uint64 values in scripts, see Scripting in WMI.

TotalVirtualMemorySize
Data type: uint64
Access type: Read-only

 

Number, in kilobytes, of virtual memory. For example, this may be calculated by adding the amount of total RAM to the amount of paging space, that is, adding the amount of memory in or aggregated by the computer system to the property, SizeStoredInPagingFiles.

For more information about using uint64 values in scripts, see Scripting in WMI.

TotalVisibleMemorySize
Data type: uint64
Access type: Read-only

 

Total amount, in kilobytes, of physical memory available to the operating system. This value does not necessarily indicate the true amount of physical memory, but what is reported to the operating system as available to it.

For more information about using uint64 values in scripts, see Scripting in WMI.
