Ever found your computer crawling to a halt? A peek into Task Manager might show the “Usermode Font Driver Host” (fontdrvhost.exe) eating up all the resources. It’s a common headache for Windows users, slowing things down and messing with your workflow.
But don’t lose hope just yet. Let’s unpack this problem and find ways to get your system running smoothly again.
What is Usermode Font Driver Host?
Fontdrvhost.exe is a genuine Windows system process that handles font management and rendering in user mode. It’s there to make sure the fonts in different applications look just right. Usually, it works quietly in the background, but sometimes it starts to use up too much memory and CPU.
Why does fontdrvhost.exe gobble up so many resources?
There are a few reasons why this might happen:
- Corrupted or old font cache: Windows keeps a font cache for quicker access. If it’s messed up or outdated, fontdrvhost.exe might overwork, leading to higher resource use.
- Problematic fonts: Some fonts, especially those from dodgy sources, might not be well-made or compatible with your system. This can make fontdrvhost.exe work harder.
- Software clashes: Some software, especially those that are heavy on graphics, might clash with fontdrvhost.exe, causing it to use more resources.
- System issues: Things like malware infections or damaged system files can also make fontdrvhost.exe act up.
How can you fix high memory and CPU usage by fontdrvhost.exe?
Try these solutions:
1. Clear the font cache
- Open the Start menu and type “services.msc.”
- Find and stop the “Windows Font Cache Service.”
- Delete everything in the
C:\Windows\ServiceProfiles\LocalService\AppData\Local\FontCachefolder. - Restart the “Windows Font Cache Service“.
2. Remove troublesome fonts
- Open the Control Panel and go to “Fonts.”
- Check your installed fonts and remove any added recently or suspicious ones.
- Restart your computer.
3. Update software and drivers
- Make sure your operating system and graphics drivers are up to date.
- Update any software that might be conflicting with fontdrvhost.exe.
4. Scan for malware
Run a thorough scan with Loaris Trojan Remover to find and remove any threats. Begin by downloading the Trojan Remover:
