Microsoft® Windows® 2000 Scripting Guide

Even though the operating systems on two different computers might have the same name and version number, those two operating systems can still differ. They might be configured with different language settings, support different encryption levels, or have different client licensing requirements.
Many differences between similar computers are reflected in the detailed property settings of their operating systems. These property settings can greatly affect the way each computer should be managed. For example, you might send a different technician to work on a computer running a Japanese version of a Windows 2000 operating system than you would send to work on a computer running a French version.
The WMI Win32_OperatingSystem class can be used to retrieve details of the operating system installed on a computer.
Important
Some of the more commonly used properties from this class are listed in Table 8.9.
Table 8.9 Win32_OperatingSystem Properties
Property | Description |
---|---|
BootDevice | Name of the disk drive from which the Win32 operating system boots. |
BuildNumber | Build number of the operating system. The build number can be used for more precise versioning information than product release version numbers. For example, 2195 is the build number for the released version of Windows 2000. |
BuildType | Type of build used for the operating system. The two primary build types are retail (the build purchased through a software vendor), and checked (test versions of the operating system that include special code to aid in debugging). |
Caption | Name of the operating system. |
CodeSet | Code page value used by the operating system. A code page contains a character table used by the operating system to translate strings for different languages. The American National Standards Institute (ANSI) lists values that represent defined code pages. If the operating system does not use an ANSI code page, this member will be set to 0. The CodeSet string can use up to six characters to define the code page value. For example, the code page value for US English is 1252. |
CountryCode | Code for the country/region used by the operating system. Values are based on international phone dialing prefixes (also referred to as IBM country/region codes). The property can use up to six characters to define the country/region code value. For example, the country code for the United States is 1. |
Debug | Operating system is a checked (debugged) build. 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 to immediately determine the cause and location of the error. Performance suffers in the checked build because of the additional code that must be executed. In general, checked builds should be used on test computers, not production computers. |
InstallDate | Date the operating system was installed, in UTC format. |
NumberOfLicensedUsers | Number of user licenses for the operating system. If unlimited, this is returned as 0. If unknown, this is usually returned as 1. |
Organization | Company name of the registered user of the operating system. |
OSLanguage | Language version of the operating system installed. Sample values for this property include: 0001 Arabic 0004 Chinese 0009 English 0401 Arabic (Saudi Arabia) 0402 Bulgarian 0403 Catalan 0404 Chinese (Taiwan) 0405 Czech 0406 Danish 0407 German (Germany) 0408 Greek 0409 English (United States) |
OSProductSuite | Installed and licensed system product additions to the operating system. Values include the following: 1 Small Business Server 2 Enterprise Server 4 Back Office Server 8 Communication Server 16 Terminal Server 32 Small Business Server (restricted) 64 Embedded NT 128 Data Center |
OSType | Type of operating system. The most common values include: 16 = WIN95 17 = WIN98 18 = WINNT 19 = WINCE The value 18 (WINNT) is returned as the OsType for Windows 2000 and Windows XP. |
Primary | Boolean value that indicates whether this is the primary operating system. This property is meaningful only on multiple-boot computers that have more than one operating system installed. |
RegisteredUser | Name of the registered user of the operating system. |
SerialNumber | Serial identification number of the operating system. |
Version | Version number of the operating system (for example, 4.0). |
Listing 8.7 contains a script that retrieves the properties of the operating system currently in use on a computer. To carry out this task, the script must perform the following steps:
This query returns a collection consisting of the operating system currently in use on the computer.
