The Regsvr32 tool is a command-line utility that can be used for registering and un-registering OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system. If you find that some of your Windows functions are note working properly, you may need to register your dll files. This tutorial will tell you how to register or unregister a DLL file using the built-in Regsvr.exe or freeware Emsa Register DLL Tool.
