I put together a little REG script ages ago that added context menus for DLLs, and EXE’s for registering and unregistering them.

I use it all the time. So much easier than invoking regsvr32 manually all the time.

Anyway, I just stumbled upon Chris Sells’ version of this script, which one-up’s mine in that he uses REGTLIB.EXE, which comes with VS6, to also register and unregister TLB and OLB files. 

And who knew that utility even CAME with VS6? I somehow have completely missed it all these years.
