The best thing about this tweak is that it is a guest, not a squatter: it added exactly one key under your user account, and removing that key restores the Windows 11 menu completely. This page is the undo, done cleanly — plus how to prove to yourself that nothing else was left behind on the PC.
People undo for good reasons: they got used to the new menu after all, the PC is being sold or handed to someone else, or they are troubleshooting and want a fully standard shell. Whatever the reason, the undo is one delete command and an Explorer restart — because the tweak never replaced, patched or installed anything in the first place.
Open Command Prompt, paste this line and press Enter:
reg delete "HKCU\Software\Classes\CLSID\{86ca1aa0-34aa-4e8b-a509-50c905bae2a2}" /f
Deleting the parent key removes the InprocServer32 marker with it — there is no second step hiding anywhere. Restart Windows Explorer from Task Manager (right click it, choose Restart), then right click a file: the compact menu is back.
regedit, EnterHKEY_CURRENT_USER\Software\Classes\CLSID{86ca1aa0-34aa-4e8b-a509-50c905bae2a2} key → Delete, and confirmSame result as the command — use whichever you are comfortable with.
The tweak's entire footprint was that one key. No program was installed, no service was added, no system file was edited, and your startup list is untouched. You can verify the clean state yourself: run the query command for the key path and Windows replies that it cannot find the specified key. In most contexts an error is bad news; here, that error is the clean bill of health.
The key is per user — that is what the HKCU branch means. On a family PC with three accounts, the undo has to be done while signed in to each account that applied the tweak. Or not at all: if the other users like their classic menu, their accounts are completely independent of yours, and your undo does not touch them. Accounts never interfere with each other here.
Almost always, Explorer simply never restarted — restart it from Task Manager and test again. If the old menu persists, check the two human errors: you are signed in to a different account than the one you deleted the key from, or you deleted a similar looking key instead of the exact GUID. The correct key's name is the full code in braces; compare it character by character before deleting anything else.
Changed your mind twice? The video's one click switcher turns the classic menu back on just as fast.
▶ Watch Full VideoYes. The add command and the delete command are a pair - run either one, restart Explorer, and that menu becomes your default. There is no limit and no wear and tear from switching.
No. The undo removes only the marker key. Programs and their right click entries are untouched; they simply move back behind Show more options in the compact menu.
No - it means the tweak is not present on this account: either it was already undone, or it was applied under a different user account on the same PC.
