regsvr32 shmedia.dll for registering a file
regsvr32 shmedia.dll /s for registering a file without the dialog box ( silent )
regsvr32 /u shmedia.dll for unregistering a file
regsvr32 shmedia.dll /u /s for unregistering a file without the dialog box ( silent )
If another copy of ''shmedia.dll'' exists in the system search path, regsvr32 may choose that copy instead of the one in the current directory. This problem can usually be solved by specifying a full path (e.g., ''c:\windows\system32\shmedia.dll'') or using the following syntax:
regsvr32 .\shmedia.dll
