Unregister, Register, Re-register DLL or OCX files in Windows 10/8/7

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 some freeware Register DLL Tools.

regsvr32-register-dll

Register dll file

To register a dll or ocx file, open a command prompt windows as an administrator, type the following and hit Enter:

This will register or unregister the dll file.

If you wish, you can also use a third-party freeware to do so easily. There are a few like Rootreg, Register/Unregister OCX/DLL Utility, RegDllView, etc, will let you do the same easily. Emsa Register DLL Tool, unfortunately, is not free anymore.
