Overview
This guide reviews University requirements for operating systems (OSes) being used by Dornsife devices. This applies to computers, tablets, and smartphones running on the following OSes:
- Windows
- macOS
- iOS
- Linux
- Android
Why the University sets these requirements
Dornsife hardware must be running an up to date operating system for the following essential reasons:
-
Data security: Keeping your computer system updated helps to safeguard you and the University from personal, financial, and reputational harms that could result from USC data being compromised in a malware attack or other security incident.
-
Network security: If your operating system is out of date and not receiving security updates, you can potentially introduce vulnerabilities into the USC network. This is the case even if you're just using your device for light Internet browsing or other non-sensitive tasks.
-
Application support: Many major vendors do not issue support patches and security updates for older operating systems. This means that if your operating system is out of date, you may not be receiving important bug fixes and support for applications such as Microsoft Office and SentinelOne.
Supported OS versions
For the 2024–2025 academic year, devices should be running on the following versions:
Windows
If your computer is running Windows 10, you will need to upgrade to Windows 11 by October 14, 2025. After this date, Microsoft will no longer provide support for Windows 10. Windows 10 LTSC, which is supported until early 2029, is only available to Windows computers that cannot upgrade to Windows 11.

How to identify the OS version and upgrade if necessary
Refer to the following how-to guides to determine what operating system version your device is running on. If your version is out of date, follow the guide to upgrade your device. You can contact DTS at any time if you would like assistance with the upgrade.
The upgrade should not affect your computer files, but we recommend having files backed up to be on the safe side. You can use a USC-approved cloud storage service (we recommend Microsoft OneDrive) or a USC-approved, encrypted storage device.
Windows instructions
How to identify the version
- In the Start menu search bar, type about and then select About this PC.
- In the "Windows specifications" section, the Edition indicates whether the system is Windows 11 or Windows 10, and the Version indicates the specific version.
How to upgrade
If your edition is Windows 10, you will need to upgrade to Windows 11:
- The upgrade should not affect your computer files, but we recommend having files backed up to be on the safe side. You can use a USC-approved cloud storage service (we recommend Microsoft OneDrive) or a USC-approved, encrypted storage device.
- In the Start menu search bar, type update and then select Check for updates.
- Click Download and install.
Options if you are unable to upgrade
If you have updates waiting for Windows 10, you may need to install those and restart your computer before the Windows 11 option is available.
If you're using an older computer and unsure whether it is capable of running Windows 11, you can check your computer's compatibility:
Once you download and install PC Health Check, open the app and click Check Now.
Linux instructions
Linux computers should be running Ubuntu 24.04 or later. For assistance with upgrading, contact DTS.
If you are using a non-Ubuntu distribution, refer to the following external pages to determine the version that your distribution should be running:
Should I upgrade to the latest version as soon as it is released?
In general, we recommend installing security updates promptly when they are made available, and no later than 60 days from when the security update is released.
However, we recommend waiting to upgrade when it comes to the latest Mac operating system from Apple. This allows time for the vendors to address initial bugs as well as for DTS to test the upgrades for compatibility with University systems. Once DTS has completed testing, we will update the Supported OS versions section of this article.
What if my device is too old to upgrade to a supported version?
If your computer or other device is too old to upgrade to a supported operating system, it no longer meets University security requirements and must be retired. Use the following form to return your device to DTS for decommissioning (retirement), as required by USC’s Asset Management Policy § 5.10:
To purchase a new computer or device, you can browse the DTS service catalog:
Requesting an exception
If your computer is being used to run research instruments, devices, or other essential programs which are not compatible with a supported operating system, let us know. DTS will evaluate these computers on a case-by-case basis and work with the USC Office of Cybersecurity to determine the options for keeping the computer in service without presenting a risk to the USC network:
My device uses an operating system that isn't listed. What are the requirements?
If you are using an operating system other than the ones detailed above, you can contact DTS for specific guidance. We can help you ensure that the device is compliant, or otherwise request an exception from the USC Office of Cybersecurity to continue using the device for University business.
