Adding an InprocServer32 subkey with a default value pointing to a DLL path is typical for:
The fact that the intended data is just 2021 (not a valid DLL path) means the registry change would break any application trying to instantiate that CLSID – because the default value should be the full path to the DLL (e.g., C:\Windows\System32\some.dll).
With data 2021, the target COM activation will fail with “Class not registered” or “Server execution failed” unless the DLL path is set elsewhere.
| Parameter | Value | Description |

| Command | reg add | Creates or modifies registry keys/values. |
| Key Path | HKCU\software\classes\clsid\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\inprocserver32 | The full path to the registry key. HKCU indicates changes apply only to the current user. |
| Value Name | /ve | Represents the default (unnamed) value of the key. |
| Data | /d "2021" | Sets the default value data to the string 2021. |
| Force Flag | /f | Overwrites existing data without prompting for confirmation. | If you encounter this registry entry on your system:
/ve: This tells the command to modify the (Default) value of the key./d "": This sets the data for the default value to an empty string./f: This forces the overwrite without asking for confirmation.If you wish to revert this change and go back to the default Windows 11 modern menu, you simply delete the key you created:
reg delete "hkcu\software\classes\clsid\86ca1aa0-34aa-4e8b-a509-50c905bae2a2" /f
Note: As of 2024, this registry tweak still functions in the latest versions of Windows 11, though Microsoft occasionally changes shell behavior in major updates.
The registry command reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /f /ve is a popular "life hack" used to restore the classic Windows 10 context menu in Windows 11.
By default, Windows 11 uses a modern, simplified right-click menu that hides many third-party options under a "Show more options" button. This registry tweak bypasses that modern menu entirely. How to Restore the Classic Context Menu
You can apply this change either via the Command Prompt or the Registry Editor. Option 1: Command Prompt (Recommended) This is the fastest method to apply the tweak. Command Prompt as an Administrator. Copy and paste the following command: To prevent accidental registry damage in the future, always:
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /f /ve To see the changes, you must restart File Explorer Task Manager (Ctrl+Shift+Esc). Windows Explorer in the list. Right-click it and select Option 2: Registry Editor If you prefer a visual interface, you can use the Registry Editor Fixing the Windows 11 Context Menu - Wolfgang Ziegler
The registry command you provided is a popular "power user" tweak used to restore the classic (Windows 10 style) right-click context menu in Windows 11. What the Command Does
Windows 11 introduced a "modern" context menu that hides many older options (like those from 7-Zip or WinRAR) behind a "Show more options" button. This command bypasses that new design.
Registry Path: HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2
Action: It creates a specific "InprocServer32" key with a blank default value. Adding an InprocServer32 subkey with a default value
Result: This tells Windows to use the legacy COM object for the context menu instead of the modern immersive one. Command Components
In Windows, reg add is used to add new keys or values to the registry.
The general syntax is:
reg add <KeyName> [/v ValueName] [/t DataType] [/d Data] [/f]
Breaking down the user’s string:
A corrected version would look like:
reg add "HKCU\Software\Classes\CLSID\86ca1aa0-34aa-4e8b-a509-50c905bae2a2\InprocServer32" /ve /d "2021" /f
Where /ve means set the default value (empty value name) to data 2021.
When Microsoft released Windows 11 in October 2021, they introduced a redesigned, simplified right-click context menu. This menu hid many useful legacy options (like "Open with," "Print," or third-party app integrations like Notepad++ or 7-Zip) behind an extra click called "Show more options."
Many power users found this change inefficient. It was discovered that by creating a specific key in the Current User (HKCU) hive and setting its default value to empty, Windows Explorer would fail to load the modern menu shell and automatically revert to the classic (Windows 10 style) context menu.
