I can understand that updates, patches, or fresh game installs would require administrative rights. However, there is no other launcher as hungry for power as the Battle.Net launcher. Other forums have recommended disabling UAC or creating a batch file/psscript that will silently bypass the prompt. The design as it stands, and the workarounds floating in the wild, are counter to everything any enterprise system shall be designed with. Please revisit the Principal of Least Privilege, unless I missed a patch that fixed this.
