CIM_OperatingSystem
An operating system is software/firmware that makes a computer system's hardware usable, and implements and/or manages the resources, file systems, processes, user interfaces, services, ... available on the computer system.

PROPERTYSMS_REPORTCIMTYPEDESCRIPTION
CaptionStringThe Caption property is a short textual description (one-line string) of the object.
CreationClassNameStringCreationClassName indicates the name of the class or the subclass used in the creation of an instance. When used with the other key properties of this class, this property allows all instances of this class and its subclasses to be uniquely identified.
CSCreationClassNameStringCSCreationClassName contains the scoping computer system's creation class name.
CSNameStringCSName contains the scoping computer system's name.
CurrentTimeZoneSInt16CurrentTimeZone indicates the number of minutes the operating system is offset from Greenwich Mean Time. Either the number is positive, negative or zero.
DescriptionStringThe Description property provides a textual description of the object.
DistributedBooleanBoolean indicating whether the operating system is distributed across several computer system nodes. If so, these nodes should be grouped as a cluster.
FreePhysicalMemoryUInt64Number of kilobytes of physical memory currently unused and available
FreeSpaceInPagingFilesUInt64The total number of KBytes that can be mapped into the OperatingSystem's paging files without causing any other pages to be swapped out. 0 indicates that there are no paging files.
FreeVirtualMemoryUInt64Number of kilobytes of virtual memory currently unused and available. For example, this may be calculated by adding the amount of free RAM to the amount of free paging space (i.e., adding the properties, FreePhysicalMemory and FreeSpaceInPagingFiles).
InstallDateDateTimeThe InstallDate property is datetime value indicating when the object was installed. A lack of a value does not indicate that the object is not installed.
LastBootUpTimeDateTimeTime when the operating system was last booted
LocalDateTimeDateTimeOperating system's notion of the local date and time of day.
MaxNumberOfProcessesUInt32Maximum number of process contexts the operating system can support. If there is no fixed maximum, the value should be 0. On systems that have a fixed maximum, this object can help diagnose failures that occur when the maximum is reached. If unknown, enter -1.
MaxProcessMemorySizeUInt64Maximum number of kilobytes of memory that can be allocated to a process. For operating systems with no virtual memory, this value is typically equal to the total amount of physical memory minus memory used by the BIOS and OS. For some operating systems, this value may be infinity - in which case, 0 should be entered. In other cases, this value could be a constant - for example, 2G or 4G.
NameStringThe inherited Name property serves as key of an operating system instance within a computer system.
NumberOfLicensedUsersUInt32Number of user licenses for the operating system. If unlimited, enter 0. If unknown, enter -1.
NumberOfProcessesUInt32Number of process contexts currently loaded or running on the operating system.
NumberOfUsersUInt32Number of user sessions for which the operating system is currently storing state information
OSTypeUInt16A integer indicating the type of operating system.
OtherTypeDescriptionStringA string describing the manufacturer and operating system type - used when the operating system property, OSType, is set to 1 ("Other"). The format of the string inserted in OtherTypeDescription should be similar in format to the Values strings defined for OSType. OtherTypeDescription should be set to NULL when OSType is any value other than 1.
SizeStoredInPagingFilesUInt64The total number of kilobytes that can be stored in the operating system's paging files. Note that this number does not represent the actual physical size of the paging file on disk. 0 indicates that there are no paging files.
StatusStringThe Status property is a string indicating the current status of the object. Various operational and non-operational statuses can be defined. Operational statuses are "OK", "Degraded" and "Pred Fail". "Pred Fail" indicates that an element may be functioning properly but predicting a failure in the near future. An example is a SMART-enabled hard drive. Non-operational statuses can also be specified. These are "Error", "Starting", "Stopping" and "Service". The latter, "Service", could apply during mirror-resilvering of a disk, reload of a user permissions list, or other administrative work. Not all such work is on-line, yet the managed element is neither "OK" nor in one of the other states.
TotalSwapSpaceSizeUInt64Total swap space in kilobytes. This value may be NULL (unspecified) if 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.
TotalVirtualMemorySizeUInt64Number of kilobytes of virtual memory. For example, this may be calculated by adding the amount of total RAM to the amount of paging space (i.e., adding the amount of memory in/aggregated by the computer system to the property, SizeStoredInPagingFiles.
TotalVisibleMemorySizeUInt64The total amount of physical memory (in Kbytes) available to the OperatingSystem. This value does not necessarily indicate the true amount of physical memory, but what is reported to the OperatingSystem as available to it.
VersionStringA string describing the operating system's version number. The format of the version information is as follows: .. or ...
