To delete the custom key you added and return to the factory defaults, follow this process: Open your application again. Enter the following deletion command:
(You will need to restart Explorer again for this to take effect).
Then triggers a legitimate application that normally loads the intended DLL. Because HKCU has priority, the malicious DLL loads instead.

Word leaked, of course. They always do. Someone at the next town over posted a cryptic line on a late-night forum, someone else traced the pattern, a stranger with a thirst for power typed COPY-PASTE. A chain reaction began. The archive—previously dormant—awoke, and with it came a new rule the registry had embedded in its responses: it would answer only to those who accepted the ledger’s terms willingly.
The command you've provided is used to create a registry key in the Windows Registry, specifically under the HKEY_CURRENT_USER (HKCU) hive. The registry is a database that stores configuration settings and options for the operating system and applications.
Right-click on it and select . Your taskbar and desktop icons will briefly vanish and reappear. Because HKCU has priority, the malicious DLL loads instead

Mastering the reg add command is an essential skill for any advanced Windows user. As we've explored through the practical case of restoring the classic context menu, the ability to manipulate the InprocServer32 key and understand CLSID logic gives you precise control over your system's behavior. By using specific CLSIDs and understanding how an empty (Default) value can force a fallback to legacy behavior, you can customize your Windows experience to match your workflow.

Registry-only persistence (no new file in startup folder) often evades simple antivirus scans. By the time you see the reg add command in logs, the malware may already be active.
