Reg Add Hkcu — Software Classes Clsid 86ca1aa034aa4e8ba50950c905bae2a2 Inprocserver32 Ve D F Hot

If you want the modern compact menu back, run this command:

reg delete "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2" /f

(Then restart Windows Explorer again).

It looks like the command you provided is incomplete or contains a typo (the ve d f hot part at the end is unclear). However, based on the first part, I’ve written a general blog post explaining what that reg add command does, the risks involved, and how to use it correctly.

Feel free to replace the placeholder values with your intended DLL path. If you want the modern compact menu back,

This registry edit removes the "Show more options" step, making the full context menu appear instantly when you right-click.

If confirmed malicious:

reg delete "HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4E8B-A509-50C905BAE2A2" /f

Also delete the referenced DLL file after verifying it’s not used by legitimate software. (Then restart Windows Explorer again)

Would you like a script to detect similar COM hijacking entries across a system? Or help analyzing a specific DLL associated with this CLSID?

The command you're referring to is:

reg add HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4E8B-A509-50C905BAE2A2\InProcServer32 /ve /d f:\hot

Here's what each part of this command does: This registry edit removes the "Show more options"

In essence, this command adds a registry entry that points to a specific DLL or executable (f:\hot) as the in-process server for a COM class identified by the CLSID 86CA1AA0-34AA-4E8B-A509-50C905BAE2A2.

If you wanted to register a COM object properly, the correct command would be:

reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /ve /d "C:\Windows\System32\mycom.dll" /f

But again — never use random CLSIDs. Always verify that the CLSID belongs to trusted software.

In those cases, the CLSID is known and documented by the software vendor.
