Reg Add Hkcu Software Classes Clsid 86ca1aa034aa4e8ba50950c905bae2a2 Inprocserver32 F Ve May 2026

Here is a corrected and complete version of the command you referenced:

reg add "HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4E8B-A509-50C905BAE2A2\InProcServer32" /ve /t REG_SZ /d "C:\Windows\System32\my_example.dll" /f

Note: The CLSID must be in standard GUID format with braces and hyphens. Your original 86ca1aa034aa4e8ba50950c905bae2a2 is valid but missing hyphens and braces – Windows expects 86CA1AA0-34AA-4E8B-A509-50C905BAE2A2.

| Part | Meaning | |------|---------| | reg add | Command to add a new registry key or value | | hkcu\software\classes\clsid\... | Registry path under HKEY_CURRENT_USER → affects only current user, not the whole system | | 86ca1aa0-34aa-4e8b-a509-50c905bae2a2 | A CLSID (Class Identifier) – normally identifies a COM object | | inprocserver32 | Subkey that defines an in‑process COM server (DLL) | | /f | Force overwrite without prompting | | /ve | Add an empty (default) value for the key |

reg delete "hkcu\software\classes\clsid\86ca1aa0-34aa-4e8b-a509-50c905bae2a2" /f

Deletes the entire CLSID entry for the current user.
(System‑wide removal would require checking HKLM\Software\Classes\CLSID\ as well.)

Final verdict:
This command, by itself, only creates an empty registry value. However, it’s a building block for COM object hijacking – a known persistence and defense evasion technique. An empty default value does no harm, but if paired with a later reg add that supplies a DLL path, it could be malicious. Here is a corrected and complete version of
