Sometimes it is useful to have the ability to re-register Windows DLL files to fix various issues in the operating system. Components of Windows which use COM/OLE/ActiveX servers need to be registered using regsvr32. For some reason, they can get unregistered and then some desktop apps won't work properly unless you register them using the command line. Having commands to register the DLL from the context menu makes this process faster. Here is how it can be done.
