What is Font Cache and How to Rebuild It in Windows 10



Font Cache works the same way as Icon Cache, and Windows operating system creates a cache for fonts to load them faster and to display them to the interface of the app, Explorer etc. If for some reason the font cache is corrupted then the fonts may not appear properly, or it starts displaying invalid font characters in Windows 10. To resolve this issue, you need to rebuild the font cache, and in this post, we will see how to do that.




How to rebuild Font cache in Windows 10



Similarly to the icon cache, Windows creates a cache for fonts to load them faster and display the user interface of apps, documents and other controls faster. When it is corrupted, fonts may not appear properly, or some fonts might be missing in the font list available for certain apps. In this article, we will see how to rebuild the font cache.


Note: If your fonts are still corrupted and displaying invalid characters after resetting the cache, the installed fonts in C:\Windows\Fonts themselves may be damaged. To restore the default fonts that ship with Windows, run the following command from an elevated command prompt:


The Windows operating system creates a cache for fonts so that each time you start an application, it loads fonts faster. However, if you have trouble displaying or using fonts, such as fonts appearing garbled, inability to switch fonts, program crashes while switching fonts, etc., then it may indicate that your font cache is corrupted. In this case, you need to clear the font cache, so that Windows operating system will rebuild it to fix any font related problems. Now, on this page, we will show you two ways to clear font cache in Windows 10.


After you have deleted all the font cache files, enable both the "Windows Font Cache Service" and the "Windows Presentation Foundation Font Cache 3.0.0.0" service. Then Windows 10 will rebuild font cache next time when it starts or restarts.


If you want an easier and faster way to clear the font cache in Windows 10, a Windows cleanup or optimization tool is a good choice. iSumsoft System Refixer is a simple but practical PC cleanup and optimization tool. It helps you remove all kinds of junk files in Windows 10, including the font cache. Follow these simple steps.


Step 3: Once the scan is complete, all unnecessary file types are displayed on the screen. Scroll down to locate the Font Cache category. Click on it and then click Clean in the pop-up dialog. This will clean all font cache files at once.


Tips: In general, font cache does not take up a lot of disk space and has no negative effect on the Windows system, so it is not necessary to clear it frequently. Deleting it does not significantly free up hard disk space or improve system performance. Only if you have font displaying problems, you need to delete the font cache to let Windows 10 reset/rebuilt it.


The Windows operating system creates a cache for the fonts so that they can load faster every time you start a program, app, Explorer, etc. But if you are facing Font problems, where the fonts are not rendering properly or displaying invalid characters on your Windows 11/10 computer, maybe the Font Cache has become corrupt. To resolve the issue, you need to reset, clear & rebuild the Font Cache. Let us see how to do it.Rebuild Font cache in Windows 11/10Type services.msc in Start search and hit Enter to open the Windows Services Manager.Locate the Windows Font Cache Service. Double-click on it to open its Properties box. Stop the Service and Disable it as well. The Windows Font Cache Service optimizes the performance of applications by caching commonly used font data. Applications will start this service if it is not already running. It can be disabled, though doing so will degrade application performance.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[300,250],'thewindowsclub_com-medrectangle-4','ezslot_3',829,'0','0']);__ez_fad_position('div-gpt-ad-thewindowsclub_com-medrectangle-4-0');Do the same for Windows Presentation Foundation Font Cache 3.0.0.0 Service as well. Stop and Disable it as well. The Windows Presentation Foundation Font Cache 3.0.0.0 Service optimizes the performance of Windows Presentation Foundation (WPF) applications by caching.Now open File Explorer, make Windows show Hidden files & folders and then manually navigate to the following location:C:\Windows\ServiceProfiles\LocalService\AppData\Localif(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'thewindowsclub_com-box-4','ezslot_2',826,'0','0']);__ez_fad_position('div-gpt-ad-thewindowsclub_com-box-4-0');Press Continue if you are asked.Once there, delete all .dat files starting with FontCache.Next, open the Font Cache folder which you see there and delete all its contents.If you are unable to delete some files, restart the computer and try. Since you have disabled both the Services, they will not start, and you will be able to delete all files.Once you have deleted the files, Enable both the Services and Start them via Services Manager.if(typeof ez_ad_units!='undefined')ez_ad_units.push([[728,90],'thewindowsclub_com-banner-1','ezslot_5',819,'0','0']);__ez_fad_position('div-gpt-ad-thewindowsclub_com-banner-1-0');Hope this helps you.Posts you may want to read:Rebuild Windows Installer Cache filesClear OneNote CacheIncrease Icon Cache sizeRebuild Icon Cache, Clear Thumbnail cacheFlush Windows DNS CacheReset Windows Store Cache.


The Photoshop font cache contains the enumerated list of fonts and font features installed to the system that Photoshop can use. Deleting this font cache file will allow Photoshop to create a new one.


If you want to test your font in a real-life situation, and you are thinking about Adobe apps, well, then you can use the Adobe Fonts folder, and avoid cache problems from the start. Congratulations: You do not need to read any further, you are done!


Why not? Because installing a font with the same name as a previously installed one can seriously mess up your font caches. Caches are collections of previously calculated data. They can speed up your computer because it does not have to reprocess the original information every time. Likewise, font caches allow your Mac to speed up the use of installed fonts because all the stuff your Mac had to calculate to make your font appear on the screen, has already been done.


Important: restarting twice is essential, because the first restart (with Shift) deletes the root of all evil, the font cache. But because it is starting in Safe Mode, some kernel extensions are not loaded, and your Mac may not appear as performant and snappy as usual. So, the second restart (without Shift) boots your Mac normally again.


Firstly, as mentioned at the beginning, test your fonts in Adobe apps. They have a special Fonts folder, fonts saved into these folders are active in Adobe apps right away, and, most importantly, they are not cached.


Secondly, if you really have to test your font in the system, then change the Family Name every time you install the font. You can extend the name by a number or a letter. Since the font caches are linked to the font name, a new installation of the font with a different name will not conflict with a previous installation. Only downside: after a few iterations, you will clutter your font menu to a point where it becomes difficult to handle.


Nico Hagenburger found out that the macOS font cache depends on the file name of the font file. So if you make sure that the OTF you export has a different file name every time you export, and you delete all previous versions, you should be fine. Nico was so nice to write a Python script called Export and Install that does exactly that. Click the link to open the script in Plugin Manager.


Once done doing this, you need to rebuild your font cache files (only if you are using Linux or some other OS for which font caches are used) so other programs can effectively use the fonts. Do this by going to your default font directory (/usr/share/fonts) and typing as root:


If you accidentally deleted or replaced one or more system fonts in Windows, you can try to restore the default fonts. The issue of missing fonts can appear as follows: in system dialog boxes (and some other windows) instead of normal characters, you can see strange or unreadable symbols. In our example, these are hieroglyphs and squares. This problem can occur after a third-party app is uninstalled, which also deleted several system default font files (up to complete cleaning the font files folder C:\Windows\Fonts). Also, the problem with fonts can occur when a certain program replaces one of the default fonts with its own one during installation. (adsbygoogle = window.adsbygoogle []).push();


Windows font caching is enabled by default (similar to icon caching). This allows loading fonts faster in Windows apps and dialogs. The font cache is located in the %WinDir%\ServiceProfiles\LocalService\AppData\Local\FontCache folder. If the font cache is corrupted, it can also cause font display issues in Windows. We recommend that you manually reset the current Windows font cache. For this you need:


If you are seeing errors similar to this and/or seeing blocks instead of characters in your application then you need to add fonts and update the font cache. This example uses the ttf-liberation fonts to illustrate the solution (after successful installation of the package) and runs as root to enable them system-wide.


Matplotlib (python-matplotlib) uses its own font cache, so after updating fonts, be sure to remove /.matplotlib/fontList.cache, /.cache/matplotlib/fontList.cache, /.sage/matplotlib-1.2.1/fontList.cache, etc. so it will regenerate its cache and find the new fonts [7]. 2ff7e9595c
