The CLSID format is: {86CA1AA0-34AA-4E8B-A509-50C905BAE2A2}
Get-ChildItem HKCR:\CLSID\{86CA1AA0-34AA-4E8B-A509-50C905BAE2A2} -ErrorAction SilentlyContinue Or use reg query :
reg query HKCU\Software\Classes\CLSID\{86CA1AA0-34AA-4E8B-A509-50C905BAE2A2}\InprocServer32 /ve Expected output: Introduction The Windows Registry is a hierarchical database
reg add HKCU\Software\Classes\CLSID\{86CA1AA0-34AA-4E8B-A509-50C905BAE2A2}\InprocServer32 /f /ve /d "" You may need administrative privileges if the key exists under HKLM instead of HKCU . For HKLM , change HKCU to HKLM and run as Administrator. Step 4: Verify and Test Query the key to confirm the default value is empty:
reg export HKCU\Software\Classes\CLSID\{86CA1AA0-34AA-4E8B-A509-50C905BAE2A2} C:\backup_clsid.reg If you are absolutely certain you want to disable the COM server: Open an elevated Command Prompt or PowerShell and run:
reg add HKCU\Software\Classes\CLSID\{86CA1AA0-34AA-4E8B-A509-50C905BAE2A2}\InprocServer32 /f /ve /d ""
Below is a comprehensive, long-form article explaining what this command does, why it is used, the security implications, and step-by-step instructions. Introduction The Windows Registry is a hierarchical database that stores low-level settings for the operating system and for applications that opt to use it. Among its most cryptic yet powerful components are CLSIDs (Class Identifiers). These globally unique identifiers (GUIDs) are used to register COM (Component Object Model) objects. why it is used
Open an elevated Command Prompt or PowerShell and run:
