RegSvrHelper is a very tiny utility. I wrote it out of frustration with having to use the command line for registering DLLs thru RegSvr32.
RegSvrHelper helps you to register/Un-register DLLs etc. It does not try to replace the RegSvr32 utility that comes with Windows, but simply 'helps' in using it by providing a file open dialog box to locate the DLL you want to register or un-register. Once you locate your DLL, you can click on the Register or Un-Register button to call RegSvr32 to do the actual registration on un-registration.
RegSvrHelper contains the usual windows conveniences you would expect. It remembers the last 20 files you registered / un-registered, and also remembers the last directory you browsed to. (Note that you must actually register / unregister a file for it to be added to the history list, simply browsing to it, or typing it in the combo box will not do so)
