How to Delete Daemon Tools From Your Computer Completely

Daemon Tools is a popular disk image emulator that lets you mount ISO and other virtual disk files without needing a physical drive. But when it's time to remove it — whether you're freeing up space, switching to an alternative, or troubleshooting conflicts — a standard uninstall doesn't always get the job done cleanly. Leftover files, registry entries, and virtual drive remnants can linger well after you think it's gone.

Here's what you need to know to remove Daemon Tools properly, and why the process varies depending on your setup.

What Daemon Tools Actually Installs on Your System

Understanding what you're removing helps you do it thoroughly. Daemon Tools doesn't just drop a single executable — it installs several components:

• Core application files in your Program Files directory
• Virtual SCSI or IDE bus drivers that let your OS recognize the emulated drives
• System tray and autostart entries that run Daemon Tools in the background on boot
• Registry keys scattered across multiple locations in the Windows Registry
• Daemon Tools Helper Service — a background process that manages virtual drive behavior

The version you installed matters here. Daemon Tools Lite (the free tier) has a lighter footprint than Daemon Tools Pro or Ultra, which install additional driver layers and services. The more feature-rich the version, the more there is to clean up.

Step 1: Unmount All Virtual Drives First 🖥️

Before uninstalling anything, open Daemon Tools and eject or unmount every virtual drive you have active. Trying to remove software while its virtual drives are still mounted can cause errors during uninstallation — or leave orphaned drive letters in your system that are annoying to remove afterward.

If Daemon Tools won't open or is already partially broken, you can also unmount drives through File Explorer by right-clicking the virtual drive and selecting "Eject."

Step 2: Uninstall Through Windows Settings

The standard removal path works for most users:

1. Open Settings → Apps (Windows 10/11) or Control Panel → Programs and Features (older Windows)
2. Search for "Daemon Tools" in the app list
3. Click Uninstall and follow the prompts

The built-in uninstaller will remove the main application and, in most cases, the core drivers. During this process you may be asked whether to remove virtual drives — say yes unless you have a specific reason not to.

On Windows 11, the app list sometimes shows Daemon Tools components separately (such as the SPTD driver layer). Uninstall those individually if they appear.

Step 3: Remove the SPTD Driver (If Present)

Older versions of Daemon Tools install a low-level driver called SPTD (SCSI Pass-Through Direct). This driver runs independently of the main application and isn't always removed by the standard uninstaller.

To check and remove it:

• Download the standalone SPTD uninstaller from the original developer (Duplex Secure) — it's a small, free tool
• Run it, select "Uninstall," and reboot when prompted

Not every version of Daemon Tools installs SPTD. Newer versions (particularly those using the DTAPI or MBR driver model) may not include it. If the standalone tool reports no SPTD installation, you can skip this step.

Step 4: Clean Up Leftover Files and Registry Entries

Even after a successful uninstall, residual files often remain:

File locations to check manually:

• C:Program FilesDAEMON Tools [Lite/Pro/Ultra]
• C:ProgramDataDAEMON Tools [version]
• C:Users[YourName]AppDataRoamingDAEMON Tools

Delete any folders that remain in these locations.

Registry cleanup is more advanced. Leftover keys can sometimes interfere with reinstallation or conflict with other disk-emulation tools. If you're comfortable in the Registry Editor (regedit), search for keys containing "DAEMON Tools" or "DT Soft" under HKEY_LOCAL_MACHINESOFTWARE and HKEY_CURRENT_USERSOFTWARE. Delete carefully — modifying the registry incorrectly can cause system instability.

For users who aren't comfortable editing the registry manually, third-party uninstaller tools (such as Revo Uninstaller or Geek Uninstaller) automate this cleanup step. These tools run the standard uninstaller first, then scan for and flag residual files and registry entries for removal.

Step 5: Reboot and Verify

After completing the steps above, restart your system. Once back in Windows:

• Open Device Manager and check the DVD/CD-ROM drives and Storage controllers sections — virtual drives created by Daemon Tools should no longer appear
• Check File Explorer to confirm no virtual drive letters remain
• Open Task Manager and verify no Daemon Tools services are running in the background

Why Results Vary Between Users 🔍

The cleanup experience differs meaningfully depending on several variables:

Someone running Daemon Tools Lite on a clean Windows 11 install will likely have a smooth, two-step removal. Someone who's had Daemon Tools Pro installed for years on a system that's been through multiple Windows upgrades may encounter more residual components and driver conflicts.

The right approach for your situation depends on which version you installed, how long it's been on your system, and whether you've had previous removal attempts that didn't fully complete. Those factors — specific to your machine — are what determine whether the standard uninstall is enough, or whether deeper cleanup is worth doing.
