No tools, no downloads. One line in Command Prompt writes the same registry key the one click script writes, Explorer restarts, and the classic menu is your default. This page walks the command slowly — what every part of that long key path means — so you are not pasting magic text into your PC blind.
The key path looks intimidating because of the long code in braces. It is actually a simple sentence: under my user account, in the shell components list, place an empty marker on the component that draws the new menu. Windows then falls back to the classic menu it still carries inside itself. Here is the command, the meaning of each piece, and the manual Registry Editor route for people who prefer clicking to typing.
cmd, and open Command Prompt — a normal window is fine, no administrator neededreg add "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}\InprocServer32" /f /ve
You should see The operation completed successfully. Then restart Explorer (card 4) or restart the PC, and right click a file to test.
HKCU is short for HKEY_CURRENT_USER — your account only, which is why no admin rights are needed. Software\Classes\CLSID is where shell components register themselves per user. The code in braces, {86ca1aa0-34aa-4e8b-a509-50c905bae2a2}, is the registered ID of the Windows 11 compact menu handler. InprocServer32 with an empty default value tells Windows this component has no server file to load for you — so Explorer falls back to the legacy menu. At the end, /f means do not ask for confirmation, and /ve means set the default value, empty.
regedit, EnterHKEY_CURRENT_USER\Software\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}InprocServer32InprocServer32, double click (Default), leave Value data empty, click OKDo not skip that last click-through: a freshly created key shows (value not set), and the tweak needs an empty string instead. Opening the dialog and pressing OK is what converts it.
The menu is drawn by Explorer, and Explorer read its configuration when it started. Until it restarts, your command has landed but nothing visibly changes — and people conclude the tweak failed. Open Task Manager with Ctrl + Shift + Esc, right click Windows Explorer, choose Restart. The taskbar flickers once; now test a right click. Signing out and back in, or a full restart, works just as well.
Wrong hive: typing HKLM instead of HKCU — that branch needs admin rights and does not drive this menu. Wrong GUID: one missing brace or digit creates a key Windows simply ignores; it is harmless, but delete it and paste instead of typing — a 38 character identifier is not a typing exercise. No Explorer restart: covered above, and responsible for most failure reports. Copy and paste beats typing for this command, every time.

A wrong path simply creates a key Windows does not use, or the command fails with an error and changes nothing. Delete any key you created by mistake and paste the command exactly as written - do not type the long GUID by hand.
There is nothing to fix on Windows 10 - it already shows the classic menu. This key only matters on Windows 11, where the compact menu exists.
