Whether you are motivated by a radical change or simply to gain fluidity, this practical guide to uninstalling League of Legends on PC aims to be comprehensive and accessible.

Why back up your data before uninstalling League of Legends on PC?

Uninstalling a game as popular and complex as League of Legends is not just about clicking a button. The first essential step is to think about backing up your data. Many players overlook this phase, which can result in the loss of custom configurations, shortcuts, or important files related to progress or game preferences.

These settings, often stored in the installation folder or in specific configuration files, are carefully adjusted after long hours of play. Imagine losing your favorite shortcut keys, your optimized mouse sensitivity, or your perfectly calibrated graphics options for your machine. This can significantly affect your future experience if you decide to reinstall the game or simply return to these settings for another title.

Moreover, if you are a versatile player who switches between several video games, losing these configurations could impact your efficiency in other digital environments. For example, a player moving from League of Legends to Brawl Stars on PC would be wise to preserve control profiles for each to maintain a harmonious gaming experience.

Here is a precise list of items to back up before starting the uninstallation:

• Your account’s personalized settings: keyboard shortcuts, audio and video options, user profiles.
• Local configuration files: often located in the installation folder or in specific subfolders.
• Saved games or gameplay-related data backups if you have files not saved in the cloud.

By taking a few minutes for this backup, you avoid potential frustrations and retain the possibility of restoring your gaming environment as you like it. Caution is thus necessary, especially when deleting a game as complex as League of Legends, whose configurations are deeply customizable.

How to uninstall League of Legends on Windows: two effective methods

Uninstalling League of Legends on Windows can mainly be done by two major methods, both accessible even to less experienced users. The choice often depends on the version of the operating system, your personal preference, or the ease of access to the menus.

Via the Control Panel

This traditional method involves:

1. Search for the Control Panel using the Windows search bar located next to the “Start” menu.
2. In the window that opens, click on Programs, then on Programs and Features.
3. Locate League of Legends in the list of applications.
4. Right-click on the game, then choose Uninstall.

This method is robust, but the player may sometimes face a block if the Riot client is still running in the background. In this case, you will have to open the Task Manager (Ctrl + Shift + Esc) and end the process “RiotClientUx.exe” or any other related Riot process.

Through Windows 10/11 Settings

For more recent versions of Windows:

1. Go to Start, click on Settings (the gear icon).
2. In the menu, select Apps & features.
3. Find League of Legends in the list and click on it.
4. Press the Uninstall button to start the removal.

The main challenge often remains that the uninstallation process can be blocked by the Riot client or that some residual files are not deleted automatically. Once the procedure is completed, manually check that the League of Legends installation folder is gone from the hard drive. If it is not, manual deletion may be necessary.

Method	Access Path	Ease Level	Risks/Limitations
Control Panel	Taskbar > Control Panel > Programs	Intermediate	Blockage if Riot client active, requires task manager
Windows 10/11 Settings	Start > Settings > Apps & features	Easy	Residual files may remain

In all cases, a PC restart is recommended after uninstallation to clarify the system state and ensure that remaining processes are terminated. This simple reflex often prevents later errors and best prepares the environment for other installations or cleanups.

Why the Riot client can block uninstallation and how to fix it

One of the major obstacles when uninstalling League of Legends is the persistent presence of the Riot client, which often runs in the background. This process often prevents the complete uninstallation of the game by locking essential files and folders.

This phenomenon is explained by the fact that Riot uses several modules that constantly communicate with servers to ensure instant updates or file synchronization. Consequently, removing League of Legends without stopping these processes can result in premature termination or incomplete uninstallation.

Here is a step-by-step guide to addressing this issue:

1. Open the task manager: Press Ctrl + Shift + Esc simultaneously.
2. Identify all Riot processes: look for “RiotClientUx.exe,” “LeagueClient.exe,” or any other related process.
3. End these tasks by selecting them and clicking End Task.
4. Restart the uninstallation process via Control Panel or Windows Settings.

For some users, it may be necessary to restart their computer after closing these processes before trying again. Additionally, it is advisable to open the Riot client before removal to let the launcher fully update. This update can fix certain bugs related to uninstallation, making the removal smoother.

If these steps are not enough, a more drastic method involves accessing the game files via right-click and “Browse game files,” then manually deleting the launcher. However, this technique should be handled with care as errors in managing system files could lead to stability issues.

Use third-party software for a complete removal of League of Legends

After attempting the classic uninstallation, traces of the game often remain on your system: backup folders, temporary files, or registry entries that penalize overall computer performance. This is why a third-party uninstaller like IObit Uninstaller is an essential ally to proceed with optimal cleaning.

IObit Uninstaller not only allows you to remove the Riot client and the League of Legends game but also to detect files scattered across your hard drive and orphan registry keys in Windows. This automated approach avoids human errors and guarantees a complete removal.

To use this software:

1. Download IObit Uninstaller from its official website.
2. Install and launch the program.
3. Browse the list of installed software and select League of Legends.
4. Click Uninstall then Deep Scan to detect all residual files.
5. Confirm the deletion of all detected items.

To complete this process, it is recommended to simultaneously use a registry cleaner tool, such as CCleaner. This clears the system of unnecessary keys and optimizes PC performance. Indeed, every trace left by an uninstalled application can slow down your machine or even cause software conflicts.

Finally, this method is perfectly suited for users looking to reinstall the game later or to free up maximum disk space while keeping a smooth computer. Clean removal has become a priority, especially with the increasing number of resource and storage-intensive video games.

Complete guide to uninstall League of Legends on Mac

Although less common, League of Legends is also played by a loyal community on Mac. Uninstallation on macOS, however, differs from that performed on Windows and deserves specific treatment.

Here is the recommended procedure for complete uninstallation:

1. Close the game and the Riot client: In the main menu, select “Quit LeagueClient” to close all related processes.
2. Delete the main folder: Open Finder, go to the Applications folder and drag the League of Legends icon to the Trash.
3. Delete residual files in the user library: Open Spotlight with Command + Shift + G, type ~/Library and press Enter.
4. In this directory, manually delete the following folders:
   • ~/Library/Application Support/Riot Games
   • ~/Library/Saved Application State/com.riotgames.LeagueofLegends.LoLPatcher.savedState
5. ~/Library/Application Support/Riot Games
6. ~/Library/Saved Application State/com.riotgames.LeagueofLegends.LoLPatcher.savedState
7. Empty the trash to finalize the complete removal.

It is important to perform this manual procedure on Mac to avoid many unwanted files lingering and clogging your system in the long run. At the same time, remember to check that your system is up to date, as macOS regularly evolves to handle the arrival of increasingly demanding and complex video games.

Clean the Windows registry after uninstallation to optimize your PC

After removing League of Legends, cleaning the Windows registry is often necessary to eliminate all traces of the application and improve your computer’s overall fluidity. The registry is a central database in Windows that stores the configurations and settings of all installed applications.

When an uninstallation is not perfect, leftover entries can cause slowdowns, startup errors, or even conflicts with other software.

To perform this cleaning, CCleaner is one of the most popular and easy-to-use free tools:

1. Download and install CCleaner from the official website.
2. Launch the software and go to the Registry tab.
3. Click Scan for Issues to detect obsolete keys related to League of Legends.
4. After the scan is complete, select Fix Selected Issues.

This operation ensures that your computer holds no “debris” from the game, which could impact performance. In 2026, with Windows systems becoming ever more complex, this step is crucial for those who want to optimize their gaming or professional equipment.

Some practical tips for successful uninstallation of League of Legends

Uninstalling League of Legends should not be taken lightly if you want to avoid technical issues and keep your PC performing well. Here is a comprehensive list of tips to guide you:

• Always close the Riot client before any uninstall attempts, notably via the task manager.
• Back up your personalized settings if you want to keep your gaming experience as it is.
