# Client patching

The system template **Client patching** installs the missing Windows updates on a client and restarts it if an update needs it. The **Patch clients** wizard sets it up as a policy (see[

**Wizards**](https://docs.xeox.com/automations/kk29w6Dr2iM3dbYa6gqsvV/wizards/6Ji769S94EEF673BAew1vL)). You find it in the **Toolbox** under **System templates**.

- **Severity**: which updates to install: **All updates**, **Critical only**, **Important or higher** or **Moderate or higher**.
- **Update age (days)**: only updates released at least this many days ago. 0 installs them as soon as they are out.
- **Restart**: **If an update needs it** or **Never**.
- **Restart after (minutes)**: how long the message counts down before the restart.
- **Message before the restart**: shown to whoever is signed in. Leave it empty to restart without a message.

The last two only appear with **Restart: If an update needs it**.

Below, you see the actions it adds:[

Reboot](https://docs.xeox.com/actions/cA3GbGqPkitikUefevioxb/reboot/4EM6MBA4qoQkU9ikadTF8u). Severity and update age are set on the task, so they apply to the installation. **Add 5 actions** puts them into the task.

> A system template is added as a copy: you can change its actions afterwards, and later versions of the template don't change them.
