====== How to Update Java ======

These are the basic steps.  You may need to modify this procedure for your own situation.

:!: On Windows-based thinclients, **you must disable -> update -> re-enable the storage write filter** or your updates **will not survive a reboot**.

This example procedure was done on an Atrust Windows-based terminal with **Windows 7 Embedded**, so we <color #ed1c24>added a couple of steps</color> to **disable the write filter** protecting its storage.  If you use a different thinclient, please adjust.

  - **Log into the workstation** as an ''administrator''
  - <color #ed1c24>(ThinClient)</color> **Disable the storage write filter**
    - <color #ed1c24>(Atrust)</color> Start -> Atrust Client Setup -> System -> FBWF
    - Disable the write filter
    - **Reboot the thinclient**
  - **Log back into the workstation** as an ''administrator''
  - **Update Java**
    - Control Panel -> Java -> Update (tab)
    - De-select (uncheck) ''Check for updates automatically''
    - Click ''Apply''
    - Click ''Update Now'' to begin
    - Confirm ''Do Not Check''
    - De-select (uncheck) ''Restore Security Prompts''
  - <color #ed1c24>(ThinClient)</color> **Re-enable the storage write filter**
    - <color #ed1c24>(Atrust)</color> Start -> Atrust Client Setup -> System -> FBWF
    - Enable the write filter
    - **Reboot the thinclient**
