How to uninstall UltraViewer completely and stop remote access

UltraViewer is a legitimate Windows remote desktop program that scammers often ask people to install. Windows does not need it, so you can remove it. Close it first, uninstall it in Settings, then check for leftovers and for other programs the caller added.

Facts checked on 16 October 2026. Steps written for Windows 11 (25H2 and 26H2) and Windows 10 22H2, read against UltraViewer's own support page and Microsoft's guidance on tech support scams.

What UltraViewer is and why a caller asked you to install it

UltraViewer is a remote desktop program for Windows. The vendor describes it as software that lets you control a partner's computer as if you were sitting in front of the screen. One person starts the program and reads out the ID and password it shows. The other person types them in, presses Connect, and can then see and control that PC.

The program is not malware. The risk is who gets your ID and password. Microsoft warns that tech support scammers ask people to install remote access software and then misrepresent normal system messages as signs of problems. It adds that Microsoft does not make unsolicited calls to offer support, so a caller who says otherwise is not from Microsoft.

Before you start: what you lose and what to note down

Removing UltraViewer costs you nothing except remote sessions made with it. There are no documents or saves inside it. You need an administrator account, because Windows asks for permission before it deletes a program. Windows 10 22H2 has been out of support since 14 October 2025, so keep it updated by other means if you still use it.

• Write down the facts of the call before you forget them: the phone number, the date, the name they gave and the amount they asked for. You will need them if you report it.
• Do not pay and do not call them back. Microsoft says it never asks for payment in cryptocurrency or gift cards.
• Close UltraViewer first if it is open, because the vendor says closing it ends the session. Step 1 does this.

How to uninstall UltraViewer, step by step

Do the steps in order. Steps 2, 3 and 4 are three ways to run the same uninstall, so stop at the first one that removes it. If the uninstall fails, go to the section "UltraViewer will not uninstall" below.

Step 1. Close UltraViewer and end its process

2 minutesNo riskA caller may still be connected, or UltraViewer is open on screen or running in the background.

The vendor's support page says that closing UltraViewer stops the session, so the other person can no longer control the PC. Ending the process also frees its files, so the uninstaller can delete them.

1. Close the UltraViewer window if one is open, and check the icons next to the clock.
2. Press Ctrl + Shift + Esc to open Task Manager.
3. If Task Manager shows a small view, click More details.
4. Right-click each entry named UltraViewer and select End task.

End only the UltraViewer entries. The old advice to end every running process can close programs you need. A stubborn program is covered in Close a frozen app (Task Manager, Force Quit).

Step 2. Uninstall UltraViewer in Windows Settings

2 minutesLow riskUltraViewer is in the list of installed apps.

This runs the program's own uninstaller, the way Microsoft recommends for any desktop program, and it removes the program files and shortcuts in one pass.

1. Right-click Start and select Settings, then select Apps.
2. Open Installed apps. On Windows 10 the page is Apps & features.
3. Type UltraViewer in the search box above the list.
4. On Windows 11, select More (three dots) next to UltraViewer, then Uninstall. On Windows 10, select the entry, then Uninstall.
5. Select Uninstall again to confirm, and Yes in the User Account Control prompt.

Every Windows uninstall screen with pictures is in Uninstall a program or app in Windows.

Step 3. Uninstall UltraViewer from Control Panel

2 minutesLow riskSettings will not open, will not list UltraViewer, or you prefer the route the vendor names.

UltraViewer's support page names the Windows programs list as the way to remove it. Control Panel shows the same entry as Settings and runs the same uninstaller, so it helps when Settings misbehaves.

1. Type Control Panel in the Windows search box and press Enter.
2. Select Programs > Uninstall a program.
3. Find UltraViewer in the list.
4. Right-click it, select Uninstall, and accept the User Account Control prompt.

The vendor's page words this as Start > Control Panel > Add or Remove Programs, which is the Windows XP name. On Windows 11 and 10 the list is called Programs and Features.

Step 4. Run the uninstaller file from the program folder

3 minutesLow riskUltraViewer is not in any list of programs, or the list entry does nothing.

Many installers keep their own uninstaller file in the program folder. Older guides and users name unins000.exe in the UltraViewer folder, so running it works even when the Windows list entry is broken.

1. Open File Explorer and paste C:\Program Files (x86)\UltraViewer into the address bar, then press Enter.
2. Find unins000.exe and double-click it.
3. Accept the User Account Control prompt.
4. Follow the on-screen instructions to the end.

Step 5. Delete the leftover program folder

2 minutesLow riskThe uninstaller reports that not all components were removed, or the UltraViewer folder is still there.

A folder that survives the uninstall holds only files of this program. Deleting it by hand removes what the uninstaller could not, and Step 1 has already released the files.

1. Open File Explorer and go to C:\Program Files (x86).
2. Click the UltraViewer folder once.
3. Hold Shift and press Delete. This skips the Recycle Bin.
4. Select Yes to confirm.
5. Select Continue when Windows asks for administrator permission.

Also delete any UltraViewer setup file in your Downloads folder.

Step 6. Remove registry keys named UltraViewer (optional)

5 minutesRead the warningYou want to remove every trace, and Steps 2 to 5 are done.

An uninstall can leave keys that carry the program's name. They do no harm, so this step is optional, but removing them leaves nothing that points at the program.

1. Back up the registry: Back up the registry before editing it. In Registry Editor choose File > Export, pick a place and click Save.
2. Select Computer at the top of the left pane, then press Ctrl + F.
3. Type UltraViewer, tick only Keys, and click Find Next.
4. If the highlighted key itself is named UltraViewer, right-click it and select Delete.
5. Press F3 to find the next one, and stop when Registry Editor says the search is finished.

Do not delete values inside other keys that only mention the program. Windows keeps lists of past programs in places that other tools read.

What UltraViewer can leave behind and where to find it

These are the traces that older guides and users report, plus the setup file named on the vendor's download link. The uninstaller may remove some of them already. Check each row once, in this order.

UltraViewer will not uninstall: each failure and its way out

• Check every Windows account on the PC. Each one can have its own copy of a program.
• Sort Installed apps by install date and look for a program you did not choose, especially another remote access tool.
• Treat a return you cannot explain as a security problem. The vendor's program has no feature that reinstalls it. Run a full Microsoft Defender scan (How to scan for malware with Microsoft Defender) and ask for IT help on a work PC.

How to confirm UltraViewer is gone

The vendor describes a connection as the ID and password that appear in the running program. With the program removed there is no UltraViewer on your PC to connect to. This does not cover other tools the caller may have added, so the next section matters if you gave them access.

After the removal: what to do if a scammer had access

If the caller only talked to you and never connected, removing the program and checking your accounts is enough. If they were connected, or if you paid or gave details, do the following. These are Microsoft's own recommendations for tech support scams.

• Run a full scan with Windows Security: How to scan for malware with Microsoft Defender.
• Install all security updates: Settings > Windows Update > Check for updates.
• Change your passwords, starting with your Microsoft account and your email, and any password you reuse elsewhere.
• Call your bank or card provider if you paid. Tell them what happened. They will probably cancel and replace the card, and you can contest the charge.
• Consider resetting Windows if fake error messages keep appearing and you gave the caller access: Reinstall Windows without losing files.
• Report the call at microsoft.com/reportascam, and tell your local law enforcement if you lost money.

Frequently asked questions

How do I uninstall UltraViewer on Windows 11?

Close UltraViewer, then open Settings > Apps > Installed apps and type UltraViewer in the search box. Select the three dots next to it, choose Uninstall, confirm, and accept the User Account Control prompt. The same steps work on Windows 11 25H2 and 26H2. On Windows 10 the page is called Apps & features and you select the entry and click Uninstall. If the entry is missing, use Step 4, which runs the uninstaller file from the program folder.

How do I stop or disconnect UltraViewer access?

Close UltraViewer. The vendor's support page says that closing the program stops the remote session, so the other person can no longer control your computer. Then end any UltraViewer entry in Task Manager with End task so nothing keeps running in the background. To make sure the caller cannot connect again through this program, uninstall it as well. Closing alone leaves the program installed and ready to start again.

How do I uninstall UltraViewer on a laptop?

A Windows laptop works exactly like a desktop PC. Follow Step 1 to close the program, then use Step 2 or Step 3 to uninstall it. The vendor says UltraViewer currently runs only on Windows, so there is nothing to uninstall on a Mac. If a caller made you install something on a MacBook, it was another program, and you should remove it from the Applications folder.

Is UltraViewer safe or a virus?

The program from the vendor's own site is real remote desktop software, not a virus. It becomes dangerous when a stranger gets your ID and password, because they can then see and control your screen. Microsoft warns that people with remote access often install malware, ransomware or other unwanted programs. So the question is who asked you to install it. If it was a caller you did not contact, remove it and scan the PC.

Can the caller still get into my PC after I uninstall UltraViewer?

Not through UltraViewer, because the vendor describes a connection as an ID and password shown by the running program, and the program is gone. They may still have another way in if they had you install a second tool or if you gave them passwords. Sort Installed apps by install date, remove anything you did not choose, run a full scan and change your passwords.

I paid or gave my details to the caller. What should I do?

Contact your bank or card provider at once, explain what happened and ask about contesting the charge. Change the passwords you shared or reuse. Microsoft says it never asks for payment in cryptocurrency or gift cards and does not make unsolicited calls. Report the call at microsoft.com/reportascam, and tell local law enforcement if you lost money. Keep the notes you made about the number and the date.

Why does UltraViewer keep coming back after I uninstall it?

The vendor's program has no feature that reinstalls it. Users report a copy returning when another Windows account on the PC has its own copy, when a second copy sits in another folder, or when a person or a work tool installs it again. Check every account and the Installed apps list. If none of this explains it, treat it as a security problem and scan the PC.

What is unins000.exe and where is it?

It is the file name that older guides and users give for UltraViewer's own uninstaller, in the program folder C:\Program Files (x86)\UltraViewer. We could not confirm the name on the vendor's site. Double-clicking it starts the uninstall the same way as the Windows list. If the folder does not exist, the program is removed or installed elsewhere. Task Manager shows the real folder with Open file location.

Should I reset Windows after a scam call?

Microsoft says to consider it if you gave scammers access to your device, and calls it the best option in some cases, for example when fake error messages keep appearing and block normal use. If you only uninstalled UltraViewer and a full scan finds nothing, a reset is usually not needed. If you reset, back up your files first, because a reset can remove them.
