How to Uninstall Supremo.exe from PC Windows (2026 Guide)

Supremo is a remote desktop tool made by Nanosystems. It is lightweight and does not always install like a traditional program. That makes removing supremo.exe a little trickier than just clicking “Uninstall” in Control Panel. This guide walks you through every method, step by step, so you can completely remove it from your Windows PC.

What Is Supremo.exe?

Supremo is a remote access application. It lets someone control your computer remotely, or lets you control another machine. It is used by IT support teams, businesses, and individuals for remote help sessions.

The executable file, supremo.exe, can run as a standalone portable app without a traditional installation. This is important because it means it may not appear in your list of installed programs. You need to know where to look.

It is not a virus by default. However, if someone installed it on your machine without your knowledge, that is a serious concern. Either way, you have every right to remove it completely.

Does Supremo Need to Be Uninstalled or Just Deleted?

This depends on how it was set up on your machine.

Setup Type	What You Need to Do
Portable (single .exe file)	Delete the file and clean up leftovers
Installed as a service	Use Settings or a dedicated removal method
Set to run at startup	Disable startup entry, then delete
Installed with persistent access	Remove service, registry entries, and file

Most IT teams configure Supremo to run as a Windows service for unattended access. In that case, a simple file delete is not enough. You need to remove the service too.

Method 1: Uninstall Supremo via Windows Settings

This works if Supremo was installed using its setup installer.

1. Press Windows + I to open Settings
2. Go to Apps then Installed Apps (or Apps and Features on Windows 10)
3. Search for Supremo in the search box
4. Click on it, then click Uninstall
5. Follow any prompts that appear
6. Restart your PC when done

If Supremo does not appear here, move on to the next method. The portable version will not show up in this list.

Method 2: Delete the Supremo.exe File Directly

If Supremo was used as a portable app, no installation was performed. In this case:

1. Open File Explorer
2. Navigate to the folder where supremo.exe is located. Common locations include:
   • C:\Users\YourName\Downloads
   • C:\Program Files\Supremo
   • C:\Program Files (x86)\Supremo
   • Desktop or any folder it was manually placed in
3. Right-click supremo.exe and click Delete
4. Empty your Recycle Bin

That removes the executable. But if a service was installed alongside it, keep reading.

Method 3: Stop and Remove the Supremo Windows Service

When Supremo is configured for unattended remote access, it installs a background service called SupremoService. This service starts automatically when Windows boots. Deleting the .exe file alone will not stop this.

Step 1: Stop the Service

1. Press Windows + R, type services.msc, press Enter
2. Scroll down and look for SupremoService or anything with “Supremo” in the name
3. Right-click it and choose Stop

Step 2: Delete the Service

1. Press Windows + R, type cmd, press Ctrl + Shift + Enter to open as Administrator
2. Type the following command and press Enter:

sc delete SupremoService

3. You should see a confirmation message: [SC] DeleteService SUCCESS
4. Restart your PC

This fully removes the service from Windows.

Method 4: Remove Supremo from Startup Programs

Supremo may be set to launch when you log into Windows. Even if you delete the file, this startup entry can cause error messages.

1. Press Ctrl + Shift + Esc to open Task Manager
2. Click the Startup tab (or Startup apps in Windows 11)
3. Look for Supremo in the list
4. Right-click it and choose Disable or Delete

Alternatively, use the Registry to find startup entries:

1. Press Windows + R, type regedit, press Enter
2. Navigate to: HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
3. Look for any Supremo entry on the right side
4. Right-click it and click Delete
5. Also check: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run

Delete any Supremo entries you find there too.

Method 5: Clean Up Leftover Files and Registry Entries

After uninstalling, leftover data can remain. Here is where to check:

Leftover Folders

Delete these folders if they exist:

• C:\Program Files\Supremo
• C:\Program Files (x86)\Supremo
• C:\ProgramData\Supremo
• C:\Users\YourName\AppData\Roaming\Supremo
• C:\Users\YourName\AppData\Local\Supremo

To reach AppData quickly, press Windows + R and type %appdata% or %localappdata%.

Leftover Registry Keys

1. Open Registry Editor (Windows + R, type regedit)
2. Press Ctrl + F to search
3. Type Supremo and click Find Next
4. Delete any keys or values related to Supremo
5. Press F3 to continue searching until no more results appear

Be careful in the Registry. Only delete keys that clearly relate to Supremo. If you are not confident, skip this step or use a tool like Revo Uninstaller which handles this automatically.

Method 6: Use Revo Uninstaller for a Complete Removal

Revo Uninstaller is a free third-party tool that scans for leftovers after uninstalling any software. It catches registry entries, folders, and files that the standard uninstaller misses.

1. Download and install Revo Uninstaller from the official site
2. Open it and find Supremo in the list of installed programs
3. Click Uninstall and choose Advanced scan mode
4. Follow the prompts to remove all detected leftovers

This is the easiest way to do a thorough removal without manually editing the Registry.

How to Verify Supremo Is Fully Removed

After removing it, confirm it is completely gone:

Check	How to Do It
No supremo.exe file	Search for “supremo” in File Explorer
No running process	Check Task Manager under Processes tab
No service	Open services.msc and search for Supremo
No startup entry	Check Task Manager startup tab
No scheduled task	Open Task Scheduler and search for Supremo

Check Task Scheduler Too

Supremo may have added a scheduled task. Open Task Scheduler:

1. Press Windows + R, type taskschd.msc, press Enter
2. Browse the Task Scheduler Library
3. Look for any task named Supremo or related to it
4. Right-click and choose Delete if found

This is a step many guides skip, but it matters for a complete removal.

Is Supremo.exe a Virus or Malware?

Supremo itself is legitimate software made by a reputable Italian company. It is not malware. You can verify this by checking its digital signature.

That said, it can be misused. If someone installed Supremo on your machine without telling you to gain remote access, that is a form of unauthorized access. You should remove it immediately and change your passwords.

If you are unsure whether the version on your machine is legitimate, run a scan with Malwarebytes to check for any signs of tampering or bundled threats.

Removing Supremo When You Cannot Find the File

Sometimes Supremo runs as a service but the original .exe has been moved or renamed. Here is what to do:

1. Open Task Manager, go to the Processes or Services tab
2. Look for anything related to Supremo
3. Right-click and choose Open File Location
4. This takes you directly to the file, wherever it is
5. Delete the file from there, after stopping the process first

Summary

Uninstalling supremo.exe from Windows depends on how it was installed. Here is a quick recap:

• If it appears in Apps and Features, uninstall it from there
• If it was portable, delete the .exe file manually
• If it ran as a service, use sc delete SupremoService in Command Prompt
• Remove startup entries from Task Manager or Registry
• Clean up leftover files from Program Files and AppData
• Check Task Scheduler for any lingering scheduled tasks
• Use Revo Uninstaller if you want an automated, thorough cleanup

Once you have done all of this, Supremo will be completely removed from your system.

Frequently Asked Questions

Why does supremo.exe not appear in Add or Remove Programs?

Supremo can run as a portable application without going through a standard installer. When used this way, Windows does not register it as an installed program, so it will not show up in the Apps list. You need to manually find and delete the .exe file and any related service it may have installed.

How do I know if Supremo is running in the background?

Open Task Manager with Ctrl + Shift + Esc. Go to the Processes tab and look for supremo.exe or SupremoService. You can also go to the Services tab and search for Supremo. If either appears, it is actively running on your machine.

Can I just end the Supremo process in Task Manager to stop it?

Ending the process stops it temporarily, but it will restart the next time Windows boots if a service or startup entry is configured. You need to remove the service and startup entries as described in this guide for a permanent fix.

Is it safe to delete the SupremoService registry keys manually?

Yes, as long as you only delete keys that specifically belong to Supremo. Do not delete keys you do not recognize. If you are uncomfortable editing the Registry, use Revo Uninstaller instead, as it handles registry cleanup safely and automatically.

After removing Supremo, should I run an antivirus scan?

It is a good practice, especially if Supremo was installed without your knowledge. Run a full scan with Windows Defender or Malwarebytes to confirm no other unwanted software was installed alongside it. This gives you peace of mind that your system is fully clean.
