What is ctfmon.exe? Should I disable it on Windows10?

A few fraudulent anti-virus and tech-support companies have been trying to present genuine processes in the Windows Task Manager as a virus or malware to fool customers into buying their product or service. One such case is with the process ctfmon.exe or CTF Loader.

What is ctfmon.exe


The ctfmon process is used by Microsoft Office to activate the Alternative User Input Text Input Processor and the Microsoft Language Bar. Ideally, it runs in the background and doesn’t interfere with the normal functioning of your system.

The process is usually triggered when you start using the recommended functionality on Microsoft Office. At times it doesn’t end automatically when all Microsoft Office applications are closed, and at times it triggers at the startup itself.

Is ctfmon.exe a virus

Cftmon.exe as explained earlier is a genuine file needed by Microsoft Office. However, many users have reported a virus with the same name. The original file is located in C:\Windows\System32. If a similarly named file is found outside that folder, it could well be a virus or malware.

To check if the file is a virus or a genuine file, right-click on the process in the Task Manager and select Open location. If the location is the original System32 folder, the file is legit and genuine. If not, then you need to run a full system anti-virus scan right away.

Can I disable ctfmon.exe on Windows 10

The possibility that cftmon.exe could be a virus isn’t the only problem with the process. Users have reported many more annoyances with it.

To prevent ctfmon.exe from running at startup, you can disable this startup item.

In case you wish to never have this process run, try using the regsvr32 tool. The Regsvr32 tool is a command-line utility that can be used for registering, and un-registering OLE controls like DLL and ActiveX (OCX) controls in the Windows operating system.

Press Win+R to open the Run window. Type the following commands one by one to unregister the DLL files, and press Enter after each of them:

regsvr32.exe /u msimtf.dll
regsvr32.exe /u msctf.dll

Restart the system once the commands have executed and the ctfmon.exe process would have been disabled.

Hope this clarifies the matter!
