¿Qué es PresentationFontCache.exe?

PresentationFontCache.exe es un servicio del sistema Windows que en realidad forma parte del .NET Framework. El objetivo principal de Presentation Font Cache es optimizar el rendimiento de los programas de Windows Presentation Foundation (WPF) almacenando en caché la información de las fuentes utilizadas. Las aplicaciones WPF iniciarán este servicio por sí mismas si no se está ejecutando en el sistema del usuario desde el principio.

En pocas palabras, Presentation Font Cache no es un intruso de la red, por lo que puedes dejar de asustarte. Estás tratando con un servicio del sistema que, por error, ha empezado a consumir los recursos de tu ordenador en cantidades insanas. Ahora intentaremos arreglarlo…

¿Cómo puedo eliminar la carga del procesador PresentationFontCache.exe?

Afortunadamente, hay una serie de métodos que pueden devolver el servicio PFC a un estado de funcionamiento normal.

Método nº 1 Borrar el archivo Font.dat

Este método es el más eficaz, si hay que creer a los usuarios de la web. Todo lo que tienes que hacer es encontrar el archivo Font.dat en tu ordenador y eliminarlo. El archivo Font.dat contiene información sobre varias aplicaciones WPF. El archivo puede causar potencialmente problemas con PresentationFontCache.exe si se ha corrompido.

Sigue estos pasos:

• Pulsa Win+R para que aparezca la ventana Ejecutar;

teclea C:{WindowsServiceProfilesLocalServiceAppDataLocal en la línea en blanco y pulsa Intro;

Nota: Si no puedes navegar hasta este directorio de esta manera, utiliza el Explorador de Windows. Asegúrate de activar la función de archivos ocultos (que se encuentra en el mismo Explorador).

• localiza el archivo Font.dat (en nuestro caso era FontCache 3.0.0.dat);
• haz clic en este archivo con el PCM y selecciona «Eliminar»;

Nota: Cierra a la fuerza el proceso PresentationFontCache.exe en el Administrador de tareas si no puedes eliminar la carpeta Font.dat.

Método nº 2 Detener el servicio de caché de fuentes de presentación

Por supuesto, puedes desactivar la caché de fuentes de presentación en tu sistema, pero esto degradará significativamente el rendimiento de todas las aplicaciones WPF. Sin embargo, si no utilizas este tipo de aplicaciones, puedes desactivar este servicio de forma segura y seguir utilizando tu Windows. Para desactivar el PFC, sigue este procedimiento:

• Pulsa Win+S para invocar el motor de búsqueda del sistema;
• haz una petición de «Servicios» y haz clic en el elemento encontrado;
• encuentra el servicio «Windows Presentation Foundation Font Cache …» en la lista y haz doble clic sobre él;
• selecciona «Desactivado» en el menú Tipo de inicio y guarda los cambios que hayas hecho;
• reinicia el PC.

Método #3 Restaurar el .NET Framework

¿Los dos métodos anteriores no te ayudaron a solucionar el problema del proceso PresentationFontCache.exe? Reparar el .NET Framework es una posible solución a la situación. Como hemos mencionado anteriormente, Presentation Font Cache forma parte de .NET Framework, por lo que es lógico que si le ocurre algo a este último, el servicio PFC podría empezar a funcionar incorrectamente.

Prueba lo siguiente:

• Pulsa Win+R;
• ejecuta «appwiz.cpl» y pulsa Intro;
• encuentra «Microsoft .Net Framework 3.0» (u otra versión) en la lista de programas, haz clic en él con PKM y selecciona «Cambiar»;
• En la nueva ventana, haz clic en «Reparar» y sigue las instrucciones que aparecen en la pantalla;
• Cuando hayas terminado con el proceso de recuperación, reinicia el ordenador.

Generalmente, el primer método funciona para la mayoría de los usuarios, pero en algunos casos tienes que utilizar las otras dos soluciones. Esperamos que este artículo haya sido suficientemente informativo y que hayas eliminado el problema del proceso PresentationFontCache.exe.

Error message or high CPU utilization when running a WPF-based application

• 4 contributors

This article helps you resolve the problem where you receive a FileFormatException or ArgumentOutOfRangeException error message in a Windows Presentation Foundation (WPF)-based program when the WPF-based program processes text.

Applies to:   Windows Presentation Foundation Original KB number:   937135

When you run a WPF-based application in the Microsoft .NET Framework 3.0, you may receive a FileFormatException error or an ArgumentOutofRangeException error. The error occurs when the WPF-based application starts to process text. For example, you may receive a FileFormatException error message that resembles the following:

file:///filepath/file_name file does not conform to the expected file format specification.

In this error message, file_name is typically the file name for a font. Additionally, the application consumes up to 100 percent CPU time.

When looking in Task Manager or other tools, PresentationFontCache.exe consumes 50% or more of available processor time.

This issue occurs if video drivers overwrite the data in the font cache that is stored in memory.

To resolve this issue, follow these steps:

Exit all WPF-based applications that are running on the computer.

Stop the Windows Presentation Foundation Font Cache 3.0.0.0 service. To stop the Windows Presentation Foundation Font Cache 3.0.0.0 service, use one of the following methods.

Method 1: Use Microsoft Management Console

• Click Start , click Run , type Services.msc , and then click OK .
• Right-click Windows Presentation Foundation Font Cache 3.0.0.0 , and then click Stop .

Method 2: Use the command prompt

• Click Start , click Run , type cmd , and then click OK .
• At the command prompt, type net stop "Windows Presentation Foundation Font Cache 3.0.0.0" , and then press ENTER .

Delete the old Fontcache3.0.0.0.dat file.

By default, the Fontcache3.0.0.0.dat file is located in the %windir%\ServiceProfiles\LocalService\AppData\Local folder in Windows Vista. By default, the Fontcache3.0.0.0.dat file is located in the %systemdrive%\Documents and Settings\LocalService\Local Settings\Application Data folder in Windows XP and in earlier versions of Windows.

Update the video card drivers. To do this, use one of the following methods.

Method 1: Use Windows Update Catalog

To update the video card drivers, check for updates in the Windows Update Catalog. For more information about how to download drivers from the Windows Update Catalog, see How to download updates that include drivers and hotfixes from the Windows Update Catalog .

Method 2: Download and then install the latest video card drivers

To download and install the latest video card drivers, contact the computer or the video hardware manufacturer.

More information

If the video card drivers overwrite the data in the font cache that is stored in memory, the corrupted data may be saved to the hard disk as a data file. Therefore, you may experience the issue that is described in the Symptoms section when another WPF-based application tries to read the corrupted data file.

After you update the video card drivers and after you delete the Fontcache3.0.0.0.dat file, a new font cache data file is created based on the new computer configuration. This new font cache data file is created when the Windows Presentation Foundation Font Cache 3.0.0.0 service is stopped. Typically, the new font cache data file is created when the computer is shut down or restarted.

Top 3 Solutions to PresentationFontCache.exe High CPU Usage

What is PresentationFontCache.exe? Why does it take so much resources? To figure out the answer, you can read this post provided by MiniTool Partition Wizard where 3 solutions to PresentationFontCache.exe high CPU usage are listed.

About PresentationFontCache.exe and Its High CPU Usage

What is PresentationFontCache.exe? Actually, it is a software associated with the .NET Framework . The software is responsible for loading the font glyphs in the memory , which enables the Windows Presentation Foundation (WPF) applications to use theses fonts. Therefore, when you run a WPF app, the PresentationFontCache.exe will be started in order to offer font’s information for the app.

However, sometimes users may find that the PresentationFontCache.exe process is using a lot of CPU resources (up to 50% or even 100% in some cases). It slows down the computer . Although they end the process in Task Manager , it could appear again after a while or when you restart the PC. PresentationFontCache.exe high CPU might also slow down the startup.

The problem has something to do with the corrupted font in the cache. After being used for some time, the font’s information may be corrupted or unresponsive, which leads to PresentationFontCache.exe stuck in a restart loop and takes too much resources.

Don’t worry. The problem can be fixed easily. If you’re bothered by the same problem, you can try the following solutions to solve it by yourself.

Solution 1: Delete FontCache.dat

When you encounter PresentationFontCache.exe high CPU usage, it is possible that the .dat file which includes information referenced to an application is corrupted. You can try deleting the file and restarting the PC to solve the problem.

Here are the detailed steps.

Step 1 : Press Win + R to invoke Run window. Then input the following command to the box and click OK to access the Local folder quickly:  C:WindowsServiceProfilesLocalServiceAppDataLocal

Step 2 : Delete the file named FontCache3.0.0.0.dat (or Font*.dat ).

Then you can reboot your computer and check whether PresentationFontCache.exe high CPU usage has been solved. If it still appears, please move on to the next solution.

You are here, how to fix: disable presentationfontcache.exe (high cpu).

Infopackets Reader Teresa P. writes:

" Dear Dennis,

My computer has been acting terribly slow! I pressed CTRL + ALT + DEL to bring up Task Manager to see what was going on, and I have a task called presentationfontcache.exe that is eating 25% of my CPU. This is an older computer, and these days I need all the CPU processing power I can get - and this definitely isn't helping! Can you please tell me how I can disable presentationfontcache.exe in Windows 7? "

My response:

I have not had this problem before so I asked Teresa if she would like me to look at the issue more closely using my remote desktop service . She agreed and allowed me to connect, and sure enough - the task 'presentationfontcache.exe' was eating 25% of her CPU.

From what I've read online, the presentationfontcache.exe file is a service used for caching fonts, related to Windows Presentation Foundation (WPF) applications. I have never seen a WPF application (that I am aware of) in the last 30 years of my computing life - however, a from a bit more research, this service seems to be related to a lot of programming-related activities, including Microsoft Visual Studio. By default any application using WPF framework will enable the Windows Presentation Font Cache service, though it's my understanding this service can safely be disabled.

After a bit more digging online, I came across some instructions that will help fix the presentationfontcache.exe from eating all the CPU, plus other instructions that explained how to disable it entirely. Unfortunately neither of the sites I visited explained how to do this clearly (for the average Joe user); as such, I've decided to completely rewrite the instructions and streamline the process to minimize the amount of steps needed - plus I'll explain how to do it in simple English.

• First, you will need to open up an administrative command prompt. To do so: click Start, then type in "cmd" (no quotes); wait for "CMD.EXE" or "Command Prompt" to appear in the list, then right click it and select "Run as Administrator".  
• The commands below will clear out the Font Cache folder, set the Windows Presentation Foundation service to manual, then restart the service. To do so: highlight the text below using your mouse: c: cd C:\Windows\ServiceProfiles\LocalService\AppData\Local\ mkdir temp move font*.dat temp REG add "HKLM\SYSTEM\CurrentControlSet\services\FontCache3.0.0.0" /v Start /t REG_DWORD /d 3 /f net stop FontCache3.0.0.0 net start FontCache3.0.0.0 echo this is a dummy line  
• Right click over top of the highlighted text above, then select "Copy" from the dialogue menu. Next, go to the administrative command prompt you opened up in Step #1 and then right click in the middle of the window and select "Paste" from the dialogue menu. The text you copied in Step #2 should now be output to the command line.  
• Now, check Task Manager to make sure presentationfontcache.exe isn't eating 25, 50, or 100% of your CPU. To do so, press CTRL + ALT + DEL on the keyboard; Task Manager will appear automatically in Windows 7 and earlier - however, for Windows 8 and 10 users, you will need to click the "Task Manager" link in order to run Task Manager after pressing CTRL + ALT + DEL on the keyboard. Once Task Manager is running, go to the "Processes" tab in Windows 7 and earlier (the "Details" tab in Windows 8 and later), and look to see if you can find the presentationfontcache.exe program and see if the CPU usage is still running rampant. If it is, then proceed to Step #5.  
• ONLY do the following steps if presentationfontcache.exe is still eating your CPU. The following steps will stop the Windows Presentation Foundation service and disable it permanently (though, this can easily be reversed). To do so, use your mouse to highlight the text below: net stop FontCache3.0.0.0 REG add "HKLM\SYSTEM\CurrentControlSet\services\FontCache3.0.0.0" /v Start /t REG_DWORD /d 4 /f echo this is a dummy line  
• Right click over top of the highlighted text above, then select "Copy" from the dialogue menu. Next, go to the administrative command prompt you opened up in Step #1 and then right click in the middle of the window and select "Paste" from the dialogue menu. The text you copied in Step #5 should now be output to the command line.

At this point, you should not see presentationfontcache.exe running in task manager, and your CPU should be running a lot more smoothly. If for some reason the presentationfontcache.exe is still running, do a reboot and that should definitely prevent it from running again.

Note that any program which relies on the Windows Presentation Foundation service may run slower, because the fonts are being cached. If you don't know which program that may be, I would not worry about it too much as the majority of programs I came across were for programming purposes.

I hope that helps!

Similar Problems

I have experienced similar problems with my HP laptop running Win10. I did not have these problems until the 1607 upgrade.

It all started in August with 100% disk usage caused by HPSupportSolutionsFrameworkService.exe. Shutting down the laptop or rebooting did not clear the problem. The service needed to be terminated using Process Explorer.

Later in September, WmUpdate caused svchost to run continuously at 12% CPU useage, As before, Process Explored fixed the problem.

Later in October, MSMPEng.exe ran continuously at 12% CPU useage. Again Process explored did the trick.

Now about every two weeks HPSupportSolutionsFrameworkService.exe acts-up with 25% CPU usage. This time I can double-click / run HP Support Assistant, immediately shut down the program and the problem clears.

I hope the new Win10 upgrade in March will fix this and other nuisance bugs with the USB and Wi-Fi. My other choice is to try a clean install with the latest “save data” option. Do you have any comments about this latest download?
