How to Register and Unregister DLL Files Using the RegSvr32 Tool
RegSvr32 is a command-line utility included in Microsoft Windows that allows users to register and unregister system files, particularly .dll files. This is crucial for making certain functionalities available to software applications that rely on these files.

Open the Command Prompt
Open the command prompt as an Administrator.

Registering a DLL File
To register the .dll file, use the command prompt to navigate to the folder containing the .dll file and then run the "regsvr32" command. You will receive a confirmation message if the .dll file is successfully registered.
-
C:\User\Username>cd c:\windows\system32
-
C:\Windows\System32>regsvr32 filename.dll

Unregistering a DLL File
Unregistering a DLL file removes its entry from the Windows registry, effectively disabling it from being used by applications. Note that some DLL files may not support unregistration.
-
C:\User\Username>cd c:\windows\system32
-
C:\Windows\System32>regsvr32.exe /u filename.dll
If successful, you will see a confirmation dialog indicating that the DLL was unregistered successfully. If you encounter an error, verify the file path and command syntax.
