## Routine updates

It is important to keep your Qubes OS system up-to-date to ensure you have the

|
||||
## Installing updates
|
||||
|

The standard way to install updates is with the **Qubes Update** tool. (However,

you can also perform the same action via the [command-line

interface](#command-line-interface).)

|

Simply follow the on-screen instructions, and the tool will download and install
|
||||
all available updates for you. Note that if you are downloading updates over Tor
|
||||
(`sys-whonix`), this can take a very long time, especially if there are a lot of
|
||||
updates available.
|
||||
|
||||
## Restarting after updating
|
||||
|
||||
Certain updates require certain components to be restarted in order for the
|
||||
updates to take effect:
|
||||
|
||||
- QSBs may instruct you to restart certain components after installing updates.
|
||||
- Dom0 should be restarted after any **Xen** or **kernel** updates.
|
||||
- After updating a template, first shut down the template, then restart all
|
||||
running qubes based on that template.
