8.3 Shut Down Platform and Execution

Disable all Workflow Groups, from the Execution Manager in Desktop, or by entering an mzsh command, for example:
```
$ mzsh mzadmin/<password> wfgroupdisable \*
```
Note!

If you use the wfgroupdisable command, make sure that you enable all system tasks again when you are done.
Stop all workflows that are not disconnected and let them finish execution.
Ensure that all users shut down any connected connected Desktops. If you want to see which Desktops that are connected, you can use the following command:
```
$ mzsh mzadmin/<password> pico -view
```
This command will also display other pico instances, such as EC/ECSAs.
Shut down the Platform and all EC/ECSAs.
```
$ mzsh shutdown Platform <ec name> <ecsa name> ...
```
