Font Size Restricted (Greyed) – Display Properties

Windows XP Font Size drop down box located in the Display Properties under the Appearance tab is restricted/disabled (greyed out). The most likely cause of this is malware utilizing Group Policy Objects which enforces policies for system settings and/or user account(s) settings. The Group Policy for Prohibit selection of font size will cause the Font Size drop down box to be restricted/disabled (greyed out) in Display Properties when enabled.

Group Policies are typically applied at businesses to control access to programs, system properties, and user account settings. For Home users, Font Size drop down box can be restricted/disabled (greyed out) by these Group Policies but usually malware is the culprit. If you are a home user and the Font Size drop down box is restricted/disabled (greyed out) from the Display Properties and looks like the pictures below then there is a good chance you are infected with malware.

NOTE

Ensure your computer is malware free before applying the following solutions.
