Removing Trinity software and settings

The following instructions are applicable to staff and postgraduates who have had their computer connected to the wired College network in College offices and labs, or to the Staff Wi-Fi network or Staff VPN service, and are either leaving College or for some other reason no longer going to connect the computer to the College network.

Note that some sections apply only to those using Windows, and some apply both to those using Windows and those using macOS. If you need any advice beyond the information provided below then please contact the IT Service Desk.

1. Copy data from College profile (Windows only)

If your Windows PC was connected to the wired network, Staff Wi-Fi or VPN service then it was confirgured to login to the College domain and you will have been logging in with your College username. When you log in with your College username Windows saves certain data to a local 'Profile' folder. This local profile folder includes the default save locations for Downloads, Desktop and Documents unless you change the settings. As you will no longer be logging into the College domain it is advised that you copy the data out of the local profile folder before disconnecting your computer from the College domain (see next section on this page).

To copy data from your College profile:

On your computer login with your College username.
Open File Explorer and browse to C:\Users\username where username is your College username. You will see a large range of subfolders here, including Downloads, Desktop and Documents.
Copy the data from this profile folder to another local profile folder on this computer or an external drive as backup.

2. Disconnect your Windows computer from the College domain (Windows only)

The following steps will disconnect your computer from the College domain, meaning you will no longer login to this computer with your College username. You will need to know how to login as a local Administrator (if you are not sure how to do this, please visit the Managing Local Administrator Profile page).

Log on as local Administrator.
Using the Search button (magnifying glass) in the bottom of the screen, type Advanced system settings
Choose View advanced system settings under Best match
Click the Computer Name tab, and then click Change.
In the Member Of section, select Workgroup, and type workgroup, then click OK.
You will be prompted for your local Administrator password once more. In the username box, type the local Administrator username in the form computername\administrator and your password, then press Enter.
After a few moments a Welcome to workgroup message will appear. Click OK, and restart your machine as prompted.

3. Remove Trellix Anti-Virus Software (Windows and macOS)

If your computer is no longer going to connect to the College network then any Trellix software installed will need to be removed as it will no longer be licensed for your use, and also may no longer function correctly.

Please contact the IT Service Desk for advice on how to uninstall the Trellix agent and McAfee Endpoint Security, and for the encryption recovery key if your device had been managed for drive encryption by IT Services.

Please note that as this software is a strict requirement while connected to the College network, these steps cannot be carried out until after you have connected to the College network for the final time.

4. Removing the MECM Agent (Windows only)

Windows PCs connected to the College wired network, Staff Wi-Fi and VPN service are setup to obtain their security updates from IT Services via a Microsoft system called MECM. If your computer is no longer going to connect to the College network then you will need to remove the MECM Agent in order for the built-in Automatic Updates service to work correctly, which is very important in order to keep your computer up-to-date with security udpates.

Please contact the IT Service Desk for the instructions to remove the MECM Agent.

5. Uninstall other Trinity-licensed software (Windows and macOS)

Many software applications you may have installed during your time using a PC or Mac on the College network are licensed for the use of College staff and students only, or are licensed for your School or Area only. If you are finishing your time in Trinity then it is important that you uninstall any such applications. These would include Microsoft 365 (Word, Excel, PowerPoint, Access, Outlook, Project, Visio), Adobe Dreamweaver, Adobe Photoshop, SPSS, ArcGIS, Matlab, Mathematica, Endnote and more.

If your computer is personally owned and you had installed or upgraded to a Pro or Education edition of Windows using the license code provided by IT Services, then you are no longer entitled to run that edition of Windows on your device when you leave Trinity. Instead, you would need to revert to the edition of Windows that was on the device when you purchased it e.g., Windows 10 Home.
