This is just a reminder for the built-in Task Sequence variables in ConfigMgr 2012 R2.
You can also find them at: https://technet.microsoft.com/en-us/library/hh273375.aspx
| Built-in Variable Name | Description |
| _SMSTSAdvertID | Stores the current running task sequence deployment unique ID. It uses the same format as a Configuration Manager software distribution deployment ID. If the task sequence is running from stand-alone media, this variable is undefined. Example: ABC20001 |
| _TSAppInstallStatus | For System Center 2012 R2 Configuration Manager only: The task sequence sets the _TSAppInstallStatus variable with the installation status for the application during the Install Application task sequence step. The task sequence sets the variable with one of the following values:
|
| _SMSTSBootImageID | Stores the Configuration Manager boot image package ID if a boot image package is associated with the current running task sequence. The variable will not be set if no Configuration Manager boot image package is associated. Example: ABC00001 |
| _SMSTSBootUEFI | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: The task sequence sets the SMSTSBootUEFI variable when it detects a computer that is in UEFI mode. |
| _SMSTSClientGUID | Stores the value of Configuration Manager client GUID. This variable is not set if the task sequence is running from stand-alone media. Example: 0a1a9a4b-fc56-44f6-b7cd-c3f8ee37c04c |
| _SMSTSCurrentActionName | Specifies the name of the currently running task sequence step. This variable is set before the task sequence manager runs each individual step. Example: run command line |
| _SMSTSDownloadOnDemand | Set to true if the current task sequence is running in download-on-demand mode, which means the task sequence manager downloads content locally only when it must access the content. |
| _SMSTSInWinPE | This variable is set to true when the current task sequence step is running in the Windows PE environment, and it is set to false if not. You can test this task sequence variable to determine the current operating system environment. |
| _SMSTSLastActionRetCode | Stores the return code that was returned by the last action that was run. This variable can be used as a condition to determine if the next step is run. Example: 0 |
| _SMSTSLastActionSucceeded | The variable is set to true if the last action succeeded and to false if the last action failed. If the last action was skipped because the step was disabled or the associated condition evaluated to false, this variable is not reset, which means it still holds the value for the previous action. |
| _SMSTSLaunchMode | Specifies the task sequence launch method. The task sequence can have the following values:
|
| _SMSTSLogPath | Stores the full path of the log directory. This can be used to determine where actions are logged. This value is not set when a hard drive is not available. |
| _SMSTSMachineName | Stores and specifies the computer name. Stores the name of the computer that the task sequence will use to log all status messages. To change the computer name in the new operating system, use the OSDComputerName variable. Example: ABC |
| _SMSTSMDataPath | Specifies the path defined by the SMSTSLocalDataDrive variable. When you define SMSTSLocalDataDrive before the task sequence starts, such as by setting a collection variable, Configuration Manager then defines the _SMSTSMDataPath variable once the Task Sequence starts. |
| _SMSTSMediaType | Specifies the type of media that is used to initiate the installation. Examples of types of media are Boot Media, Full Media, PXE, and Prestaged Media. |
| _SMSTSMP | Stores the name or IP address of a Configuration Manager management point. |
| _SMSTSMPPort | Stores the management point port number of a Configuration Manager management point. Example: 80 |
| _SMSTSOrgName | Stores the branding title name that is displayed in a task sequence progress user interface dialog box. Example: XYZ Organization |
| _SMSTSPackageID | Stores the current running task sequence ID. This ID uses the same format as a Configuration Manager software package ID. Example: HJT00001 |
| _SMSTSPackageName | Stores the current running task sequence name specified by the Configuration Manager administrator when the task sequence is created. Example: Deploy Windows 7 task sequence |
| _SMSTSRunFromDP | Set to true if the current task sequence is running in run-from-distribution-point mode, which means the task sequence manager obtains required package shares from distribution point. |
| _SMSTSSiteCode | Stores the site code of the Configuration Manager site. Example: ABC |
| _SMSTSType | Specifies the type of the current running task sequence. It can have the following values: 1 – indicates a generic task sequence. 2 – indicates an operating system deployment task sequence. |
| _SMSTSTimezone | The _SMSTSTimezone variable stores the time zone information in the following format (without spaces): Bias, StandardBias, DaylightBias, StandardDate.wYear, wMonth, wDayOfWeek, wDay, wHour, wMinute, wSecond, wMilliseconds, DaylightDate.wYear, wMonth, wDayOfWeek, wDay, wHour, wMinute, wSecond, wMilliseconds, StandardName, DaylightName Example: For the Eastern Time U.S. and Canada, the value would be 300,0,-60,0,11,0,1,2,0,0,0,0,3,0,2,2,0,0,0,Eastern Standard Time,Eastern Daylight Time |
| _SMSTSUseCRL | Specifies whether the task sequence uses the certificate revocation list when it uses a Secure Socket Layer (SSL) certificate to communicate with the management point. |
| _SMSTSUserStarted | Specifies whether a task sequence is started by a user. This variable is set only if the task sequence is started from the Software Center. For example, if _SMSTSLaunchMode is set to SMS. The variable can have the following values:
|
| _SMSTSUseSSL | Specifies whether the task sequence uses SSL to communicate with the Configuration Manager management point. If your site is running in native mode, the value is set to true. |
| _SMSTSWTG | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Specifies if the computer is running as a Windows To Go device. |
| SMSTSAssignmentsDownloadInterval | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Use this variable to specify the number of seconds to wait before the client will attempt to download the policy since the last attempt (which returned no policies). By default, the client will wait 0 seconds before retrying. You can set this variable by using a prestart command from media or PXE. |
| SMSTSAssignmentsDownloadRetry | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Use this variable to specify the number of times a client will attempt to download the policy after no policies are found on the first attempt. By default, the client will retry 0 times. You can set this variable by using a prestart command from media or PXE. |
| SMSTSAssignUsersMode | Specifies how a task sequence associates users with the destination computer. Set the variable to one of the following values.
|
| SMSTSDownloadProgram | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Use this variable to specify an Alternate Content Provider, a downloader program that is used to download content instead of the default Configuration Manager downloader, for the task sequence. As part of the content download process, the task sequence checks the variable for a specified downloader program. If specified, the task sequence runs the program to perform the download. |
| SMSTSDownloadRetryCount | For System Center 2012 R2 Configuration Manager only: Use this variable to specify the number of times that Configuration Manager attempts to download content from a distribution point. By default, the client will retry 2 times. |
| SMSTSDownloadRetryDelay | For System Center 2012 R2 Configuration Manager only: Use this variable to specify the number of seconds that Configuration Manager waits before it retries to download content from a distribution point. By default, the client will wait 15 seconds before retrying. |
| SMSTSErrorDialogTimeout | When an error occurs in a task sequence, a dialog box is displayed that is automatically dismissed after a number of seconds specified by this variable. By default, the dialog box is automatically dismissed after 900 seconds (15 minutes).. |
| TSErrorOnWarning | For System Center 2012 R2 Configuration Manager only: Use this variable to specify whether the task sequence engine considers a detected warning as an error during the Application Installation task sequence step. The task sequence sets the _TSAppInstallStatus variable to Warning when one or more applications, or a required dependency, did not install because a requirement was not met. When you set the TSErrorOnWarning variable to True and the _TSAppInstallStatus variable is set to Warning, it is treated as an error. A value of False is the default behavior. |
| SMSTSLanguageFolder | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Use this variable to change the display language of a language neutral boot image. |
| SMSTSLocalDataDrive | Specifies where temporary files are stored on the destination computer while the task sequence is running. This variable must be set before the task sequence starts, such as by setting a collection variable. Once the task sequence starts, Configuration Manager defines the _SMSTSMDataPath variable once the Task Sequence starts. |
| SMSTSMPListRequestTimeout | For System Center 2012 R2 Configuration Manager only: Use this variable to specify how many milliseconds a task sequence waits before it retries to install an application after it fails to retrieve the management point list from location services. By default, the task sequence waits 60,000 milliseconds (60 seconds) before it retries the step, and retries up to three times. This variable is applicable only to the Install Application task sequence step. |
| SMSTSPersistContent | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Use this variable to temporarily persist content in the task sequence cache. |
| SMSTSPostAction | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: Specifies a command that is run after the task sequence completes. For example, you can use this variable to specify a script that enables write filters on embedded devices after the task sequence deploys an operating system to the device. |
| SMSTSPreferredAdvertID | Forces a specific targeted deployment on the destination computer to be run. This can be set through a prestart command from media or PXE. If this variable is set, the task sequence overrides any required deployments. |
| OSDPreserveDriveLetter | For System Center 2012 Configuration Manager SP1 and System Center 2012 R2 Configuration Manager only: This variable determines whether or not the task sequence uses the drive letter captured in the operating system image WIM file when applying that image to a destination computer. In Configuration Manager with no service pack, the drive letter captured in the WIM file is used when applying the operating system image WIM file. In Configuration Manager SP1, you can set the value for this variable to False to use the location that you specify for the Destination setting in the Apply Operating System task sequence step. For more information about the Apply Operating System task sequence step, see the Apply Operating System Image section in the Task Sequence Steps in Configuration Manager topic. |
| SMSTSRebootDelay | Specifies how many seconds to wait before the computer restarts. The task sequence manager will display a notification dialog before reboot if this variable is not set to 0. Examples: 0 30 |
| SMSTSRebootMessage | Specifies the message to display in the shutdown dialog box when a restart is requested. If this variable is not set, a default message will appear. Example: This computer is being restarted by the task sequence manager. |
| SMSTSRebootRequested | Indicates that a restart is requested after the current task sequence step is completed. If a restart is required, just set this variable to true, and the task sequence manager will restart the computer after this task sequence step. The task sequence step must set this task sequence variable if it requires the restart to complete the task sequence step. After the computer is restarted, the task sequence will continue to run from the next task sequence step. |
| SMSTSRetryRequested | Requests a retry after the current task sequence step is completed. If this task sequence variable is set, the SMSTSRebootRequested must also be set to true. After the computer is restarted, the task sequence manager will rerun the same task sequence step. |
| SMSTSUDAUsers | Specifies the primary user of the destination computer. Specify the users by using the following format. Separate multiple users by using a comma (,). Example: domain\user1, domain\user2, domain\user3 For more information about associating users with the destination computer, see How to Associate Users with a Destination Computer. |
