Option 3

Uninstalling Garena or LoL Client does not completely remove all of its data in the system. It needs manual deletion from the user to eradicate remains. Make use of Windows Run tool and key-in the directories below:

Use Search and Run to easily locate files and folders Windows Key+R or Start → Accessories → Run

The following are common files and folders (as of v7.17) that can be left behind after uninstall:
%allusersprofile%
%appdata%
%commonprogramfiles%
%commonprogramfiles(x86)%
%homedrive%
%localappdata%
%programfiles%
%programfiles(x86)%
%temp%

Like with remaining files and folders, there are also registries that are not deleted after uninstalling. Manually removing at Windows Registry would also remove the remains.

At Windows Run or Search, type regedit

HKEY_CURRENT_USER\Software
HKEY_LOCAL_MACHINE\SOFTWARE
HKEY_USERS\.DEFAULT\Software
HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node

Please take careful grounds and certainty in using the Registry Editor as it can damage your system.

It is advisable to create a backup (export .reg) before modifying anything.

Tip: Make use of CTRL+F and F3 with Garena or League of Legends keywords for easier search.

Q: Why do we need to reinstall?
A: When experiencing bug splats, crashes, unresponsive client, broken files, corrupted data etc. and the suggested workarounds can't resolve the issue, then we resort to re installation.

Q: Why complete re-installation than mere uninstalling?
A: Users tend to uninstall programs at Control Panel which does not complete remove the program's data. The data left behind would only slow down the system and is without any good use. Hence by complete re-installation, if done completely, would eradicate the leftovers.

Q: Why not use Third-Party Software such as CCleaner?
A: It is known that the software also fails to completely uninstall the programs and chances are, they cause more complication on the system (i.e. detecting a registry file which is a system file.

Q: How can I see hidden folders?
A: At Control Panel → Folder Options → View Tab → Tick "Show Hidden Files, Folders and Drives"

Q: Is there a need to reinstall Garena when having problem with LoL client only?
A: Not at all. You can just reinstall the game client only.
