Register a DLL File in Windows XP and Vista

Step 1: First click on Start, then Run.

Step 2: Now all you have to do to register a DLL file is to type in the regsvr32 command, followed by the path of the DLL file.

regsvr32 “C:\Windows\System32\myfile.dll”

 Step 3: Now click OK and you should get a confirmation message that the DLL has been registered successfully.

That’s it! Now your DLL has been successfully added to the registry and can be used by Windows programs.
