Using ActiveX Compatibility Manager

ActiveX Compatibility Manager is a standalone executable, and it doesn't require any installation process or additional DLLs. In order to start using it, just copy the executable file (acm.exe) to any folder you like, and run it.
The main window of acm displays the list of all ActiveX components that are currently available for enabling/disabling. For components that are currently installed on your computer, additional information is also displayed: product name, company name, description, version, filename, and more...
If you want to disable an ActiveX component that doesn't appear in the list, you can add it to the list by using "Add New Items" option. On the "Add New Items" window, you can type one or more CLSIDs or ProgIDs separated by comma or enter key. For example: if you want to add ADODB.Stream and ShockwaveFlash.ShockwaveFlash components to the list: You can simply type their CLSIDs:
