What is a CLSID file?

The Class ID, or CLSID, is a serial number that represents a unique ID for any application component in Windows. In practice, this means all registry entries for an application component can usually be found under the registry key HKEY_CLASSES_ROOT\CLSID\{CLSID value}.

What is CLSID in registry?

The CLSID or Class Identifier is a string of alphanumeric (both numbers and alphabet characters) symbols that are used to represent a specific instance of a Component Object Model or COM-based program. Your most likely encounter with the CLSID is when a website asks you to update ActiveX or another program.

How do you find a CLSID?

You can find a folder called CLSID under your DLL name. On the right side you can see a column ‘Data’, that is your CLSID.

Where are COM objects stored?

Most COM servers (code implementing a COM object) are implemented in a DLL whose path is stored in the registry key e.g. under InprocServer32. This is useful because reverse engineering may be required to understand undocumented COM objects. On Windows 7, a total of 8,282 COM objects were enumerated.

Where can I find DCOM CLSID?

Grant the user permissions to start the COM component:

  1. Click Start, Select Run, type regedit in the Open box, and then click OK.
  2. Locate and then click the following registry subkey: HKEY_CLASSES_ROOT\CLSID\CLSID value.
  3. In the right pane, double-click AppID. The Edit String dialog box appears.

Where do I find Appid in component services?

In Component Services, double-click Component Services, double-click Computers, double-click My Computer, and then click DCOM Config.

What is the IClassFactory interface for CLSID objects?

Most class objects used to create objects from a CLSID support the IClassFactory interface, an interface that includes the important CreateInstance method. You implement an IClassFactory interface for each class of object that you offer to be instantiated. (For more information about implementing IClassFactory, see Implementing IClassFactory .)
