When opening a document in Microsoft Word, you receive one of the following error messages:
There is insufficient memory or disk space. Word cannot display the requested font.
Not enough system resources to display completely.
Note
Error messages also occur in other Office applications (such as Microsoft Excel, or Microsoft PowerPoint).
The permissions of the Fonts folder may be different from the default permissions (see the following screenshot for the default permissions). To check the default permissions, open a Command Prompt window and run the icacls C:\Windows\Fonts command.
Cause
When upgrading from Windows 7, Windows 8, or Windows 8.1 to Windows 10, certain fonts aren't available with the default post-upgrade. To reduce the operating system footprint, improve performance, and optimize disk space usage, many of the fonts included with prior versions of Windows were moved to the optional features of Windows 10. If you install a fresh instance of Windows 10 or upgrade an older version of Windows to Windows 10, these optional features aren't enabled by default. As a result, fonts appear to be missing from the system.
If permissions for the C:\Windows\Fonts folder were changed or are different from the default permissions, they will persist after the upgrade, causing the issue.
Resolution
If you have documents created using the missing fonts, they might display differently on Windows 10.
For example, if you have an English or a Roman Alphabet Language version of Windows 10 installed, you might notice that the following fonts are missing:
Gautami
Meiryo
Narkism/Batang
BatangChe
Dotum
DotumChe
Gulim
GulimChe
Gungsuh
GungsuhChe
If you want to use these fonts, enable the optional feature to add them to your system. Be aware that this is a permanent change in behavior for Windows 10.
