By madmaxOfficial Patch for the WoW Launcher. This will give you the official Wrath of The Lich King style Launcher.
These launcher work with Classic and upwards.
Once on the mega site just right-click and download the patch you want.
Download page includes:
wow-184.108.40.2067-enGB-tools-patch.exe wow-220.127.116.117-enUS-tools-patch.exe Important Notes
To run these with a Classic or Burning Crusade clients, you will need to add a "Set patchlist 127.0.0.1" or "Set patchlist logon.covenant-wow.com" to the realmlist.wtf file. This prevents the launcher from attempting to update.
This edit also needs to be made with a Wrath of The Lich King client, located in Data/enUS/realmlist.wtf
