## Security updates
Security updates are an extremely important part of keeping your Qubes
installation secure. When there is an important security issue, we will issue a
[Qubes Security Bulletin (QSB)](/security/qsb/) via the [Qubes Security
Pack (`qubes-secpack`)](/security/pack/). It is very important to read each new
QSB and follow any user instructions it contains. Most of the time, simply
[updating your system normally](#routine-updates) will be sufficient to obtain
security updates. However, in some cases, special action may be required on
your part, which will be explained in the QSB.
## Routine updates
It is important to keep your Qubes OS system up-to-date to ensure you have the
latest [security updates](#security-updates), as well as the latest
non-security enhancements and bug fixes.

update notifications for them. Therefore, you should regularly update such
templates manually instead.
## 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).)
[![Qubes Update](/attachment/doc/r4.0-software-update.png)](/attachment/doc/r4.0-software-update.png)
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.
