Didn’t receive the update?

If your computer does not receive the update, you will receive popup messages that workstation updates are available. Click here for instructions on how to install the updates manually.

Workstation update: On campus

If your workstation is located on campus, please leave it turned on to help facilitate the installation.

  • If a workstation is on and unattended, the updates will load automatically.
  • If you are at a workstation, here’s what to expect during the update:
    1. You will receive an install notice with a countdown timer displaying the number of minutes until the download begins.
    2. Log off the workstation before the countdown reaches zero. The updates will then begin automatically.
    3. Workstations will not be connected to Texas Children’s network during the updates.
    4. The updates will restart the workstation. Reboot warnings will appear before the machine restarts.
Workstation update: Teleworkers

If you telecommute, follow these steps to receive updates to your TCH computer:

  1. Lock your computer, leave it on and connected to VPN (if applicable). This will help to facilitate the installation of the updates if your TCH device is connected remotely.
  2. Your TCH workstation will REBOOT during this process, possibly several times, so please save all current work.
  3. Remote note: These steps apply only to TCH assets (e.g. laptop) that are connected remotely via VPN. For people that connect via on home PCs, there is nothing to do, since your assets in the office will update automatically.
