The specific command in question appears to modify or add a value to a CLSID's InprocServer32 key in the registry, changing or setting it to "2021". The purpose of doing so would depend on the requirements of the software component identified by the CLSID 86CA1AA0-34AA-4E8B-A509-50C905BAE2A2. | Parameter | Value | Description | |
No legitimate Microsoft COM object uses a year number as InprocServer32 default value. The proper data would be like:
/d "C:\Program Files\SomeApp\some.dll"
Use reg.exe from an elevated or normal command prompt depending on whether you edit HKCU (no elevation required) or HKLM (requires elevation). Use reg
Basic syntax:
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /ve /t REG_SZ /d "<value-data>" /f
If you want to set a named value (for example ThreadingModel): If you want to set a named value
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /v "ThreadingModel" /t REG_SZ /d "Apartment" /f
The CLSID 86ca1aa0-34aa-4e8b-a509-50c905bae2a2 is not a standard Microsoft CLSID. A search in known databases (like Microsoft’s official CLSID list, WinReg, or COM registry) does not show it as a built-in Windows class.
This suggests one of three possibilities:
Without verifying the actual registry after running the command, it’s impossible to know which software uses it.
reg delete "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2" /f
If you meant the /d value to be "2021" (not a DLL path), then:
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /ve /d "2021" /f
