0

Whenever you’re going through processes running on your task manager, you tend to see some processes that seem strange and suspicious. The usermode font driver host is one such process.

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

In this article, I will explain using mostly Windows 10 what the usermode font driver host actually 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?

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 itself, it 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.

This means 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. 

If you’ve not installed the latest Windows updates, you’re not safe yet. You’re still at risk so it is important that you 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 versions of Windows might be wondering what they have to do, especially if they don’t want to update to more recent Windows OS versions. 

Well, Microsoft made some security changes that can also 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 that have 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 fonts activity only. 

This ensures the security I explained earlier that the latest Windows updates brought. The UMFD-0 account is there to ensure 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 how important this process is and I’m sure you also understand the increased security measures around the process. 

Sometimes though, 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 a legit one. 

You can find out by checking the file path of the process and also by checking 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 and not a virus imitating it.

If it isn’t under a UMFD-0 account, then your suspicion has probably been confirmed. 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 absolutely confirm that it is legit. 

Other earlier Windows versions users can just use this method to check if the fontdrvhost.exe process is a virus or not.

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.

If the file path matches C:\Windows\System32 then the process is the real deal. If the file path does not match what is above, you definitely need to run a full scan of your system ASAP using a really good antivirus program.

Note: The fontdrvhost.exe file should be about 800kb in size. If you find out that the size is considerably more than this, then something else might be wrong and you should do a full scan just to be sure.

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 is starting up (sometimes when it’s even already running). 

To put it in a simpler way, when fontdrvhost.exe is loaded(or loading) during Microsoft Office Access 2010 startup, this error sometimes occurs. 

What Causes The Errors To Occur?

When Microsoft Office Access 2010 is displaying fontdrvhost.exe runtime errors, this is usually due to the fact that it cannot locate the file during startup.

It could also be the file has become corrupted which will also cause the error message to pop up. 

Either way, what will happen is that the Microsoft Office Access will immediately close and it won’t open until you fix the error disturbing it’s the startup.
