CCleaner and similar registry cleaners sometimes identify orphaned DLLs related to integration plugins as "unused" and delete them. This breaks the Uplay integration specifically.

GOG Galaxy is a launcher developed by CD Projekt (the creators of Cyberpunk 2077 and The Witcher). Unlike Steam or Epic Games, GOG Galaxy is built around DRM-free gaming. However, to integrate with games that were not originally purchased on GOG, GOG Galaxy uses "integration plugins."
Galaxywrp.dll is specific to the Uplay (now Ubisoft Connect) integration. When you connect your Ubisoft account to GOG Galaxy, the launcher downloads Galaxywrp.dll to read the local save files and achievements from Ubisoft games (like Assassin’s Creed or Far Cry) and "wrap" them into the GOG ecosystem.
Without this DLL, your Ubisoft games would appear as "external executables" without any overlay or tracking features.
