2025 Uninstall Idm Completely From Your Windows Pc

by

Are you running into the frustrating “fake serial number” error with Internet Download Manager (IDM)? Often, the solution is a complete and total removal of the software before reinstalling it. Simply uninstalling from the Control Panel isn’t enough, as it leaves behind files and registry entries that can cause issues later.

Many users think the standard uninstallation process removes every trace of a program, but with powerful tools like IDM, leftover data can persist. This guide will walk you through the definitive process to completely uninstall IDM from your Windows PC, ensuring a clean slate for a fresh installation.

How to Completely Uninstall IDM from Your PC: A Step-by-Step Guide

A complete guide on how to uninstall IDM completely from a Windows PC to remove all files and registry entries.

Follow these three essential steps to ensure every component of Internet Download Manager is removed from your system.

Step 1: Standard Uninstallation via Control Panel

First, we’ll start with the standard uninstallation process. This removes the main program files.

  • Open your Control Panel and navigate to Programs and Features.
  • In the list of installed software, find and select Internet Download Manager.
  • Click the Uninstall button at the top.
  • An IDM uninstallation window will appear. When asked to choose an uninstallation method, select Full. This option attempts to remove user settings and download history.
  • Click Next, and then Finish to begin the process.
  • Once finished, you might see a prompt to restart your computer. Click “Cancel” for now, as we still have more cleanup to do.

Pro Tip:

Choosing the “Full” uninstallation is crucial because it targets user-specific data and settings that the “Default” option often leaves behind. This is the first line of defense against persistent errors on reinstallation.

Step 2: Clean Up the Windows Registry

This is the most critical step for a truly clean removal. IDM leaves behind keys in the Windows Registry that a standard uninstall misses. Warning: Editing the registry can be risky. Follow these instructions carefully and do not delete anything you are unsure about.

  • Press the Windows Key + R on your keyboard to open the Run dialog box.
  • Type regedit into the box and press Enter or click OK. You may need to grant administrator permission.
  • In the Registry Editor, press Ctrl + F to open the Find window.
  • In the “Find what” box, type Internet Download Manager and click Find Next.
  • The search will locate folders (keys) and files related to IDM. Right-click on each found entry or folder that clearly belongs to “Internet Download Manager” or “IDM” and select Delete.
  • Press F3 to repeat the search and find the next entry. Continue deleting all related entries until the search finds nothing more.

Pro Tip:

Before deleting anything in the Registry Editor, it’s a wise practice to create a backup. Go to File > Export, choose a safe location, give the file a name (like “RegistryBackup”), and save it. If anything goes wrong, you can restore it by going to File > Import.

Step 3: Delete Remaining Files and Folders

Finally, let’s delete any leftover folders from the installation directory to complete the cleanup.

  • Open File Explorer and navigate to your main system drive, which is usually the C: drive.
  • Go into the Program Files (x86) folder (or Program Files if you’re on a 32-bit system).
  • Find the folder named “Internet Download Manager”.
  • Right-click the folder and press Shift + Delete. This permanently deletes the folder, bypassing the Recycle Bin. Confirm the action if prompted.

With all traces of IDM removed, you should now restart your computer. This final step is essential for Windows to process all the changes and complete the uninstallation. After restarting, you can perform a fresh installation of IDM, and the “fake serial number” error should be gone.

Frequently Asked Questions (FAQ)

  • Why do I need to edit the registry to uninstall IDM?

    A standard uninstallation often leaves behind configuration settings, license data, and other traces in the Windows Registry. These leftovers can cause conflicts or trigger errors like the “fake serial number” message when you try to reinstall. Editing the registry ensures all traces are truly gone.

  • Is it safe to delete files from the Registry Editor?

    It is safe as long as you only delete entries that you are certain belong to Internet Download Manager. Deleting the wrong system file can cause instability. If you’re unsure, it’s best to follow our Pro Tip and back up your registry before you begin.

  • Will this permanently fix the “fake serial number” error?

    This process provides a clean slate. After a complete uninstall and restart, a fresh installation of IDM with a legitimate license will work correctly. If you are using unofficial versions, the error may reappear. The best long-term solution is to purchase a genuine IDM license.

  • What if I can’t find the IDM folder in Program Files?

    If the folder isn’t in C:\Program Files (x86) or C:\Program Files, it’s likely the standard uninstaller (Step 1) successfully removed it. However, you should still check the AppData folder for leftovers by typing %appdata% in the File Explorer address bar and looking for an IDM or Tonec folder.
