How to Uninstall Trend Micro OfficeScan Without Password

Uninstalling Trend Micro OfficeScan without a Password

Upgrading to Windows 10 but can’t uninstall Trend Micro OfficeScan due to a forgotten password? Not to worry – with a few clever tricks, we can banish this outdated antivirus software without the need for any passwords whatsoever.

In this quick guide, we’ll walk through several methods to forcefully uninstall OfficeScan, ranging from built-in Windows tools to third-party solutions. By the end, your system will be free and clear to upgrade to Windows 10 without compatibility issues.

Using the Windows Registry Editor

Our first method relies on adjusting settings in the Windows registry – essentially a database that controls various configuration options. Here’s how:

First, launch the Registry Editor by hitting Windows+R, typing "regedit", and pressing Enter. Navigate through the folder structure toHKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\TrendMicro\PC-cillinNTCorp\CurrentVersion\Misc.

Can trend uninstall if I don’t have a password?

Trend can also supply you with the proper tools to uninstall if you do not have the password, but they require you contact them directly for obvious reasons. As far as a script, Trend may also be able to supply one, but in any case, will probably require the client systems to reboot in order to complete the uninstall.

How do I uninstall Trend Micro?

Once there, on the right pane, double click on Allow Uninstall and change the value to 1. Click on OK. Close registry editor and try uninstalling Trend Micro. If you are unable to change the registry value, you may want to boot the computer into Safe Mode and then try changing the registry.

In the right-pane, double-click the key named "Allow Uninstall" and change its value to 1. Click OK to save the change. This simple tweak tells OfficeScan that uninstallation is permitted.

Close the Registry Editor and attempt to uninstall OfficeScan through the normal Control Panel route. With the password check disabled, it should fully remove without any prompts.

However, if the Registry Editor itself is password-protected on your system, this method won’t work. We’ll need to explore some alternatives.

Leveraging the Command Prompt

Our next approach relies on the Command Prompt’s power to forcefully stop program processes.

Launch an Administrator Command Prompt and run the following command:

"C:\Program Files (x86)\Trend Micro\OfficeScan Client\ntrmv.exe" /forceclean

This will trigger OfficeScan’s self-cleaning procedure to begin removal. Wait for the operation to fully complete.

Unlike the registry approach, Command Prompt bypasses any password restrictions. However, it still relies on OfficeScan’s own uninstaller, which could get obstructed.

Booting in Safe Mode

If all else fails, booting in Safe Mode provides an operating environment free from many typical restrictions. This can allow OfficeScan to be uninstalled smoothly.

Are Trend Micro agents compatible with Linux?

Trend Micro releases agents for major Linux versions, such as Red Hat Enterprise Linux 9. Minor Linux versions such as Red Hat Enterprise Linux 9.x are also compatible if they use a kernel that the agent supports.

To enter Safe Mode, restart your PC and continually tap the F8 key during bootup. Select "Safe Mode with Networking" from the menu and press Enter.

Once loaded in Safe Mode, follow the standard Control Panel uninstallation process for OfficeScan. With limited drivers and software active, it should proceed unimpeded.

The downside is having to reboot every time. But for one-off stubborn uninstalls, it’s a handy trick.

Third-Party Uninstallers

Finally, dedicated uninstallers like Revo Uninstaller and IObit Uninstaller are expressly designed to remove stubborn programs. They can dig deeper than standard Windows tools.

After installing one, run it and target OfficeScan for removal. The advanced algorithms work to fully eliminate registry traces, folders, and files.

This method is quick and straightforward. But it requires downloading separate software when built-in options may still do the job.
