Add the same key with PowerShell (run as administrator):
New-Item -Path "HKCU:\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" -Force | Out-Null
Set-ItemProperty -Path "HKCU:\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" -Name "(default)" -Value ""
To remove:
Remove-Item -Path "HKCU:\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2" -Recurse -Force
The correct syntax for reg add is:

At its heart, this command wants to add or modify a registry key under:
The InprocServer32 subkey is where Windows COM (Component Object Model) looks for the DLL file path for an in-process server. Add the same key with PowerShell (run as
reg query "HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4e8B-A509-50C905BAE2A2\InprocServer32" /ve
Expected output:
Default REG_EXPAND_SZ C:\MyLib\MyCOM.dll
reg add "HKCU\Software\Classes\CLSID\86CA1AA0-34AA-4e8B-A509-50C905BAE2A2\InprocServer32" /ve /d "C:\Disabled.dll" /f
It may also belong to a legitimate but obscure component. However, a known legitimate mapping is not widely documented. Always verify with the software vendor or via VirusTotal.
Editing COM registration is powerful and can be used for legitimate per-user installs, troubleshooting, or targeted tweaks to shell behavior — but it carries real risk if misapplied. Treat registry changes like surgery: back up, proceed deliberately, and test.

The registry command reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /f /ve is used to restore the classic Windows 10 style right-click context menu in Windows 11.
In Windows 11, the default right-click menu is a simplified version that hides many third-party app options behind a "Show more options" button. Executing this command overrides the modern menu component, allowing the full legacy menu to appear by default. How to Use the Command
To apply this change without manually navigating the Registry Editor, follow these steps:
Open Command Prompt: Press the Windows Key, type cmd, and select Run as administrator. The correct syntax for reg add is: reg

Restart Windows Explorer: For the changes to take effect, you must restart the explorer process. You can do this by running:taskkill /f /im explorer.exe & start explorer.exe.Alternatively, you can find Windows Explorer in the Task Manager , right-click it, and select Restart. How the Command Works
