Deploying and uninstalling the Coro Agent with Windows Server GPO
This guide explains how to deploy and uninstall the Coro Agent on your Windows endpoint devices using the Windows Server Group Policy Object (GPO) manager.
Important
Coro recommends creating a new GPO specifically designed for deploying the Coro Agent.
Deploying the Coro Agent using a new deployment GPO
To create a deployment GPO:
- From your Windows server device, access the Group Policy Management console (select Windows Key + R , enter gpmc.msc , and select OK ).
-
Create a GPO and provide a name.
note
The GPO name must not exceed the Windows 260 character path limit and must not contain special characters.
-
Link the GPO to the domain or the dedicated organizational unit (OU) containing the target devices for Coro deployment.
After creating and linking the new GPO, make a note of the ID of the policy (double-click the GPO and select the Details tab):
-
Download the Coro Agent Windows PowerShell deployment script and configure it for your workspace, as shown:
Important
When deploying the Coro Agent via an RMM, run the script under the Local System account (SYSTEM) to ensure it has the necessary permissions.
Replace the following variable markers in the script with real values:
- $url : The download URL for the latest version of the Coro Agent installer for Windows, obtained from the Coro console. For details, see Deploying Coro on Windows devices .
- $newFilename : The .msi installer filename, extracted from the download URL.
For example, if you use the following download URL:
https://s3.amazonaws.com/client-repo.coro.net/beta/win/releases/2.0.412.1/CoroInstaller.msi?response-content-disposition=attachment%3B%20filename%3DCoroInstaller_123abc-456def-789abc.msi&AWSAccessKeyId=AKIA5XP6&Signature=y4V3Tq2dU9mE%3D&Expires=2005954595This results in the following script values:
Important
Make sure you do not delete the quotation marks when replacing the placeholder text.
note
Coro generates a unique installer filename for each workspace. Therefore, you must create a copy of the standard Coro deployment script and repeat this process for each workspace.
Save this script as a PowerShell file on the Windows server device hosting your Active Directory and GPO, in the following location:
\\[your domain]\sysvol\[your domain]\Policies\{ID of GPO obtained in Step 2 above}\MACHINE\Scripts\Startupnote
If do not have sufficient permissions to save files to this location, save the script to:
C:\Windows\SYSVOL\domain\Policies\{ID of GPO obtained in Step 2 above}\Machine\Scripts\Startup -
In the
Group Policy Management Editor
, right-click the newly created group policy object and select
Edit
:
-
Go to
Computer Configuration > Policies > Windows Settings > Scripts (Startup/Shutdown)
:
-
Double-click
Startup
:
Windows Server GPO displays the Startup Properties dialog.
-
Select the
PowerShell Scripts
tab and then select
Add
:
Windows Server GPO displays the Add a Script dialog.
-
Select
Browse
:
-
Go to the location where you saved the PowerShell script file and then select
Open
:
-
Select
OK
:
Coro adds the file to the PowerShell Scripts tab in the Windows PowerShell Startup Scripts for Local Computer section of the Startup Properties dialog.
-
Select
Apply
and then select
OK
:
The settings are saved, and the Startup Properties dialog closes.
- From the same GPO settings, go to Computer Configuration > Policies > Administrative Templates > System > Scripts .
-
Double-click
Specify maximum wait time for Group Policy scripts
:
Windows Server GPO displays the Specify maximum wait time for Group Policy scripts settings dialog. This setting specifies the maximum duration allowed for all scripts to finish execution.
-
Configure the settings as follows:
- Select Enabled .
- In the Options section enter the desired number of Seconds for the wait time:
note
Consider the number of startup items when setting the wait time. Typically, a wait time between 60-120 seconds is recommended.
- Select OK to save your changes and then close the Group Policy Management Editor .
-
Select your GPO from the
Group Policy Management
console and then select the
Delegation
tab:
-
Select
Add
:
Windows Server GPO displays the Select User, Computer, or Group dialog.
-
Select
Object Types
:
-
Select
Computers
and then select
OK
:
-
Enter
Domain computers
into the
Enter the object name to select
field and then select
OK
:
Windows Server GPO dispays the Add Group or User dialog:
-
Select
Read
from the
Permissions
dropdown and then select
OK
:
A Domain Computers entry is added to the Delegation section:
Applying the new GPO to all organizational unit devices
Important
Coro strongly recommends creating a dedicated OU in your Active Directory for all devices intended for Coro deployment. This is necessary because the Group Policy Management console does not display the default Computers and Users OU in Active Directory:
After you create the OU, link the new policy to it to ensure that the policy applies to all devices:
note
Depending on your environment and specific configuration, you can also link this new GPO to the entire domain.
After you have linked the new policy to the OU perform the following steps to apply the GPO to all devices in the OU:
-
Go to the
Scope
tab of the newly created GPO:
-
Select
Add
from the
Security Filtering
section:
-
Select
Computers
and then select
OK
:
-
Enter
Domain computers
into the
Enter the object name to select
field and then select
OK
:
Windows Server GPO applies the GPO to all devices in the OU which are linked to the newly created policy:
note
If you want to deploy Coro to selected devices without creating a dedicated OU, or if you want to use an existing OU other than the default Computers OU, you must add the individual workstations to the Security Filtering section, rather than Domain Computers:
Important
Coro strongly recommends that you create a dedicated OU in your Active Directory for all workstations intended for Coro deployment, instead of adding individual workstations to the policy.
-
Reboot your devices at least twice to ensure that the group policy changes take effect. Alternatively, execute the command
gpupdate /forcein a Command Prompt to apply the policy; in this case, only one reboot is necessary.
Troubleshooting
If Windows Server GPO fails to apply the policy:
- Go to the Group Policy Results module in the Group Policy Management console.
- Run the wizard against the device in question (right-click the Group Policy Results item and then select Group Policy Results Wizard .)
-
Verify that the policy is applied to the device:
If Windows Server GPO successfully applies the policy:
- The policy instructs the device to download and install the Coro agent. The time this takes can vary based on internet speed, and deployment progress may not be immediately visible.
- Deployment might also be affected by any existing internet restrictions. Wait 15-20 minutes to allow the installation to complete before starting any troubleshooting.
If the policy does not take effect after several reboots and a waiting period:
- Determine if other restrictive policies might be interfering with policy application. You can check which policies are affecting the workstation by adding it to the Group Policy Results module in the Group Policy Management console.
- Policy application might fail if Windows Firewall settings block communication between the device and the domain controller. If so, temporarily disable Windows Firewall, reboot the device, and check if this resolves the issue.
Uninstalling the Coro Agent with Windows Server GPO
Important
Coro recommends creating a new GPO specifically designed for uninstalling the Coro Agent.
Follow the same steps described in Deploying the Coro Agent to uninstall the Coro Agent from your Windows devices through Windows Server Group Policy Object (GPO) manager. You can obtain a Windows PowerShell uninstall script as follows:

########################
# IMPORTANT #
# This script requires elevated privileges (Run PowerShell as Admin) to work.
# If you are deploying it via GPO or any other RMM, they will already run it in elevated mode, unless specifically configured otherwise.
# However, if you run it locally as a user, you must make sure your PowerShell instance is elevated (Run PowerShell as Admin), otherwise the script will fail.
# This script can be used both locally and with GPO or any other RMM that support PowerShell. However, some specific RMMs only support limited PowerShell commands, so this script might not work on these. In this case, please contact Coro support for help.
##########################################################
#### BYPASS SWITCH #######################################
##########################################################
#This script will always attempt to uninstall Coro using native methods (MSI package) and will only resort to a manual uninstall if the native methods fail
#However, in some specific scenarios, it might be required to skip the native method and instruct the script to directly execute a manual uninstall (for example, when we need to uninstall Coro version 2.0.42.1 if it fails to update to the latest version)
#For those cases, set the value of the variable below to $true. This will instruct the script to skip native uninstall methods and immediately proceed with the manual uninstall.
#The script will still check for Tamper Protection status because if it is enabled, we can only uninstall Coro in Safe Mode.
#If that's the case, simply run the script in Safe Mode (with or without the switch below as it is not triggering in Safe Mode), and it will uninstall Coro manually.
$skipNativeUninstall = $false #Use only when asked to do so by Support: set this variable to $true to skip native uninstall methods.
