Disable the unnecessary plugins
IntelliJ IDEA is shipped with a variety of plugins that provide integration with different version control systems and application servers, add support for various frameworks and development technologies, etc.
On the next step you can disable the plugins you do not need to increase IntelliJ IDEA performance. If necessary, you can re-enable them later in the Settings dialog ( Ctrl+Alt+S under Plugins).
You can click the Disable All link for each group of plugins to disable them all, or Customize to disable individual plugins.
Download and install additional plugins
On the next step, you are prompted to download additional plugins that are not bundled with the IDE from the IntelliJ IDEA plugins repository:

After you have completed initial IntelliJ IDEA configuration, the Welcome screen will be displayed. It allows you to:
Register IntelliJ IDEA
To try and evaluate IntelliJ IDEA, you can download and install its trial version for free. The trial version is available for 30 days, whereupon you need to obtain and register a license.
- Do one of the following:
- On the Welcome screen, click Configure | Manage License
- Select Help | Register from the main menu
- Select how you want to register IntelliJ IDEA:
- JetBrains Account: select this option if you have a JetBrains Account that allows you to access your purchases and manage licenses (see What is JetBrains Account? to learn more).
- Activation code: select this option if you have an activation code for IntelliJ IDEA, and paste it to the text area.
- License server: select this option to register IntelliJ IDEA through the License Server web application that allows you to manage floating licenses and issue licenses to users who do not have direct internet access.
Update IntelliJ IDEA
Out of the box, standalone IntelliJ IDEA installation is configured to check for updates automatically. It will notify you when a new version is available :
IntelliJ IDEA updates are usually patch-based: they are applied to the existing installation and only require you to restart the IDE. Note that these patches can only be applied sequentially, on top of one another. If an update is ignored or skipped, subsequent updates cannot be applied. Updating IntelliJ IDEA in this case will require either downloading and reinstalling it or using the Ignored updates list to apply updates one by one.
If you do not want to install the proposed update for some reason, you can ignore it by clicking the Ignore This Update button in the update dialog box. The ignored build's number will be added to the Ignored updates list, and you will not be prompted to install this particular build until you remove it from the list.
Manage IntelliJ IDEA through Toolbox App
Toolbox App is a control panel that allows you to manage all JetBrains developer tools, including IntelliJ IDEA, as well as your projects, from a single point of access. It lets you maintain different versions of the same tool, install updates and roll them back if needed. It also remembers your JetBrains Account and uses it to automatically log you in when you install and register new tools.
- Download Toolbox App.
- Launch the setup file.
Now you can manage existing tools, install new tools and download updates:
Perform silent install on Windows
Silent installation is performed without any user interface. It can be used by network administrators to install IntelliJ IDEA on a number of machines and avoid interrupting other users.
To perform silent install, run the installer with the following switches:
/S: Enable silent install
/D: Specify the path to the installation directory
/CONFIG: Specify the path to the silent configuration file
ideaIU.exe /S /CONFIG=d:\temp\silent.config /D=d:\IDE\IntelliJ IDEA Ultimate
Silent configuration file
You can download the silent configuration file for IntelliJ IDEA at https://download.jetbrains.com/idea/silent.config
The silent configuration file defines options for installing IntelliJ IDEA. With default options, silent installation is performed only for the current user (
mode=user). If you want to install IntelliJ IDEA for all users, open the silent configuration file with a text editor, change the value of the installation mode option (
mode=admin) and run the installer as an administrator.
