I suppose that -u will also work. But when I run REGSVR32 without any parameters this is what I get:

---------------------------
RegSvr32
---------------------------
No DLL name specified.

Usage: regsvr32 [/u] [/s] [/n] [/i[:cmdline]] dllname
/u - Unregister server
/s - Silent; display no message boxes
/i - Call DllInstall passing it an optional [cmdline]; when used with /u calls dll uninstall
/n - do not call DllRegisterServer; this option must be used with /i
---------------------------
OK
---------------------------

So MS recommends I use /u rather that -u
