As part of my daily IT routine, I had to use a magical, mystery disc from AT&T/SBC to install a DSL line in one of our offices. This disc, as I suspected, installed a bunch of ride-along software (in addition to letting me configure the account on AT&T/SBC servers, which was all I really wanted out of the disc in the first place). All ranting about how much this whole process sucks aside, I was able to use standard methods to uninstall everything it installed with one exception. For whatever reason, the SBC Self Support Tool’s uninstaller did not remove the product. I found an uninstall.exe in the Program Files/SBC Self Support Tool folder, but when running it it would simply prompt that I had to uninstall from the Add/Remove Programs option in the Control Panel. (Which no longer showed the SBC Self Support Tool, presumably because it thought it was already uninstalled.) Ugh, Windows.

Anyway, the fix is to simply run that same Uninstall.exe with a command line of SBC, you could do the following from the Start/Run:
“c:\program files\sbc self support tool\uninstall.exe” SBC

Update – 19-Oct-2008: (As per David in the comments, be sure to include the quotes!)

Don’t know if anyone will need this info, but I found it in one of the install logs from the product, and thought it might help someone else out.
