The little known secret of regsvr32.exe is…

You ready?

You can load multiple DLLs at the same time.

Yup. And not just one extra, but many.

Let’s have a look at an example:

regsvr32.exe c:\WINDOWS\system32\hhctrl.ocx foo

will first load c:\WINDOWS\system32\hhctrl.ocx and then foo.dll.

We can do it multiple times:

regsvr32.exe hhctrl.ocx hhctrl.ocx hhctrl.ocx hhctrl.ocx hhctrl.ocx foo
