Will I lose any of my data in the upgrade?

  • No, your data will be preserved during the upgrade. Regardless, this is a good time to double check that OneDrive is correctly syncing and backing up your files! 





Why do I have to upgrade?

  • Starting on October 14th, 2025, Microsoft will officially end its support of Windows 10. This means that important security updates will no longer be deployed, making these machines inherently dangerous to the CSU network. Any Windows 10 computers identified after this date are required to be removed from our network to ensure security. 





The Windows 11 upgrade isn't showing up in Software Center.

  • The most common reason for this is that your computer is not eligible to upgrade to Windows 11. The easiest solution would be to replace the computer with one that can upgrade to Windows 11. You can find information on standard options by visiting the CAS IT Hardware Ordering Form.





What should I do if my computer can't upgrade to Windows 11?

My Computer needs to be Windows 10 for a specific application or lab instrument.
