Razer Synapse is free software used to configure and customize Razer hardware. It lets you remap buttons, create macros for games, change your device's RGB lighting colors, and save those personalized settings to the cloud so they work on any computer.

So why Razer Synapse won't uninstall? The software is difficult to fully clean out because of how deeply it integrates into the operating system.  

4 reasons why you cannot uninstall Razer Synapse:

1. Active Background Services: Active background tasks deployed by Razer Synapse will block the uninstaller if any of them are still running.

2. Corrupted Uninstaller Logs: If a previous software update was interrupted, or if your system crashed, the internal uninstaller file can become corrupted.

3. Dependency Conflicts: If these system files (.NET Framework / C++) are broken or undergoing an update, Synapse won’t be removed successfully.

4. Deep Windows Registry Ties: Standard Windows uninstallation often leaves behind Registry keys, which can trick your system & prevent a clean reinstall.
