Usermode Font Driver Host (fontdrvhost.exe): What It Is

You tend to see strange and suspicious processes when you’re going through processes running on your task manager. The usermode font driver host is one such process.

Users generally don’t know the process, so they assume it’s a virus or something else harmful to their system.

In this article, I will explain using mostly Windows 10, what the usermode font driver host is, what it does, and why you can’t get rid of it. I will also be showing you how to check if the process is not a virus.

What Is The Usermode Font Driver Host?

Note: This is the name of the process’s executable – (fontdrvhost.exe), and this is what you’ll see running.

The easiest explanation is that the process helps with font activity on your system. The job is already implied in the name. 

An executable created by Microsoft is now a vital part of system processes. 

In older versions of Windows OS, this process was susceptible to being cloned by viruses and malware (or hijacked), and that’s why in the latest Windows updates, it runs in an App Container.

If the process is infiltrated, the only damage that can be done will be contained inside the App Container and not throughout your system processes. 

You’re not safe yet if you’ve not installed the latest Windows updates. You’re still at risk, so you must update now to ensure you get the best protection possible for this important process.

Security For User With Older Versions Of Windows (Windows 7 & 8)

Users of older Windows versions might wonder what they have to do, especially if they don’t want to update to more recent Windows OS versions. 

Microsoft made some security changes that can safeguard your system from infiltration through the fontdrvhost.exe process.

Check the Microsoft Security Update Guide – ADV200006 for the measures you can put in place on your older version of Windows.

Why Is UMFD-0 Running On My System, And What Does It Have To Do With The fontdrvhost.exe Process?

For folks with the latest Windows updates, when you try to find the fontdrvhost.exe process in your task manager, you will see that the process runs under the name – UMFD-0

Don’t fret just yet; this is a legit process. What the UMFD-0 represents is an account under the User Mode Driver Framework that limits the fontdrvhost.exe process’s access to font activity only. 

This ensures the security I explained earlier that the latest Windows updates brought. The UMFD-0 account ensures the process reach does not extend to more than font activity.

How To Check If The fontdrvhost.exe Process Is Not A Virus

I have tried explaining this process’s importance, and I’m sure you also understand the increased security measures around the process. 

Sometimes, users might still not be convinced that it isn’t a virus. Perhaps you might have been burned before by a virus masquerading as a legit process. 

Well, I don’t blame you for being cautious. I’m only going to explain how to make sure it’s not a malicious process pretending to be legit. 

You can find out by checking the process file path and what it runs under in your Task Manager.

Checking What It Runs Under In Your Task Manager (For Folks With The Latest Updates)

This is probably the easiest one. It is something I’ve already explained above. 

Open your Task Manager (right-click on your taskbar and choose task manager from the list of options that appear)

Then check the fontdrvhost.exe. If it’s running under the UMFD-0 account, then you’re sure it’s the real process, not a virus imitating it.

Your suspicion has probably been confirmed if it isn’t under a UMFD-0 account. Please run a dependable antivirus program to clear out viruses and harmful processes.

Checking The File Path Of The Process

This is more for general use. Even if you’ve tried the process above (meant for updated Windows 10 users), you can still use this method to confirm that it is legit. 

In other earlier Windows versions, users can use this method to check whether the fontdrvhost.exe process is a virus.

Open your task manager (like I explained above) and look for the fontdrvhost.exe (Usermode Font Driver Host) process. 

Right-click on it and go to Open File Location in the list of options that will appear.

Fixing Errors Associated With The fontdrvhost.exe (Usermode Font Driver Host) Process When Using Microsoft Office Access 2010

(Runtime) errors from this process are naturally associated with Microsoft Office Access. 

This is because the fontdrvhost.exe runtime errors usually occur whenever Microsoft Office Access 2010 starts (sometimes when it’s already running).
