NAME Add-MpPreference
SYNOPSIS
Modifies settings for Windows Defender.
SYNTAX
Add-MpPreference [-CimSession <CimSession[]>] [-ExclusionExtension <String[]>] [-ExclusionPath <String[]>] [-ExclusionProcess <String[]>] [-Force]
[-ThreatIDDefaultAction_Actions <ThreatAction[]>] [-ThreatIDDefaultAction_Ids <Int64[]>] [-ThrottleLimit <Int32>] [<CommonParameters>]
DESCRIPTION
The Add-MpPreference cmdlet modifies settings for Windows Defender. Use this cmdlet to add exclusions for file name extensions, paths, and
processes, and to add default actions for high, moderate, and low threats.
PARAMETERS
-CimSession [<CimSession[]>]
Runs the cmdlet in a remote session or on a remote computer. Enter a computer name or a session object, such as the output of a New-CimSession
or Get-CimSession cmdlet. The default is the current session on the local computer.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ExclusionExtension [<String[]>]
Specifies an array of file name extensions, such as obj or lib, to exclude from scheduled, custom, and real-time scanning. This cmdlet adds
these file name extensions to the exclusions.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ExclusionPath [<String[]>]
Specifies an array of file paths to exclude from scheduled and real-time scanning. You can specify a folder to exclude all the files under the
folder.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ExclusionProcess [<String[]>]
Specifies an array of processes, as paths to process images. This cmdlet excludes any files opened by the processes that you specify from
scheduled and real-time scanning. Specifying this parameter excludes files opened by executable programs only. The cmdlet does not exclude the
processes themselves. To exclude a process, specify it by using the ExclusionPath parameter.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-Force [<SwitchParameter>]
Forces the command to run without asking for user confirmation.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThreatIDDefaultAction_Actions [<ThreatAction[]>]
Specifies an array of the actions to take for the IDs specified by using the ThreatIDDefaultAction_Ids parameter. The acceptable values for
this parameter are:
-- 1: Clean
-- 2: Quarantine
-- 3: Remove
-- 4: Allow
-- 8: UserDefined
-- 9: NoAction
-- 10: Block
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThreatIDDefaultAction_Ids [<Int64[]>]
Specifies an array of threat IDs. This cmdlet adds the default action for the threat IDs that you specify.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
-ThrottleLimit [<Int32>]
Specifies the maximum number of concurrent operations that can be established to run the cmdlet. If this parameter is omitted or a value of 0
is entered, then Windows PowerShell???? calculates an optimum throttle limit for the cmdlet based on the number of CIM cmdlets that are running
on the computer. The throttle limit applies only to the current cmdlet, not to the session or to the computer.
Required? false
Position? named
Default value none
Accept pipeline input? false
Accept wildcard characters? false
<CommonParameters>
This cmdlet supports the common parameters: Verbose, Debug,
ErrorAction, ErrorVariable, WarningAction, WarningVariable,
OutBuffer, PipelineVariable, and OutVariable. For more information, see
about_CommonParameters (http://go.microsoft.com/fwlink/?LinkID=113216).
INPUTS
OUTPUTS
Example 1: Add a folder to the exclusion list
PS C:\\> Add-MpPreference -ExclusionPath "C:\\Temp"
This command adds the folder C:\\Temp to the exclusion list. The command disables Windows Defender scheduled and real-time scanning for files in
this folder.
