Undo-SbecActiveConfig

Undo-SbecActiveConfig is accessible with the help of BootEventCollector module. To configure BootEventCollector, go through this link.

Synopsis

Reverts a change to the active configuration.

Description

The Undo-SbecActiveConfig cmdlet reverts a change to the active configuration of the Setup and Boot Event Collector.

If multiple backup configuration files are available, you can apply Undo and Redo operations sequentially to move through the configurations backwards and forwards.

If the previous active configuration was not itself restored but set afresh (or checkpointed after restore), it is saved in a backup file. When doing multiple undo/redo/restore commands in a sequence, the intermediate configurations are not saved in the new backup files. A configuration from undo/redo/restore commands is automatically considered checkpointed if it was left unchanged for an hour.

You can use the OldTimestamp parameter to modify the configuration atomically.

The restored configuration is re-checked for validity, and refused if it has become corrupted.

You must have the Builtin Administrator privilege to run this command.

Parameters

-CimSession

Runs the cmdlet on the remote computers through a remote session. Enter a session object, such as the output of a New-CimSession or Get-CimSession cmdlet or an array of these objects. The default is to run the cmdlet on the local computer. For more information, see About_CimSession.

-ComputerName

Specifies the names of the computers on which you want to perform the operation. You can specify a fully qualified domain name (FQDN), a NetBIOS name, or an IP address for each computer. For more information, see Invoke-CimMethod on MSDN.

-Continue

Specifies that this operation will not throw an exception if a failure occurs. Instead the caller should examine the output of the cmdlet for the error information.

-OldTimestamp

Specifies the timestamp of the previous active configuration. This provides a way to perform the atomic changes of the configuration. Each configuration has a timestamp (the time when it was last set or restored) and an original timestamp (if the configuration was restored, the time when it was originally set, otherwise the same as the normal timestamp). This operation checks that the OldTimestamp value matches either the normal or original timestamp of the current active configuration thus ensuring that the active configuration wasn’t changed since the last time you have looked at it. If the values do not match, an error is returned.

Syntax

Undo-SbecActiveConfig [[-OldTimestamp] <UInt64>] [-Continue] [[-ComputerName] <String[]>] [[-CimSession] <CimSession[]>] [<CommonParameters>]

—————–Example 1—————–
Undo a configuration change
PS C:\> Undo-SbecActiveConfig -Continue | Format-List
This command reverts a configuration change to the active configuration, and passes the resulting hash table to Format-List, which formats it.

—————–Example 2—————–
 Undo a configuration change and throw on errors
PS C:\> $res = Undo-SbecActiveConfig; $res = Undo-SbecActiveConfig -OldTimestamp $res.OriginalTimestamp
This command undoes two configuration changes, ensuring that no other changes are done in between, and throwing on errors.
