You may be unable to remove the Read-Only attribute from a folder using Windows Explorer. In addition, some programs may display error messages when you try to save files to the folder.

This behavior occurs because the folder is customized. You can customize a folder by clicking Customize this folder on the View menu. Many programs also customize folders (for example, the Fonts folder comes with a customization as part of the standard system configuration).

Windows Explorer uses the Read-Only attribute to determine whether or not the folder is customized. To work around this behavior, you can configure Windows Explorer to use the System flag instead of the Read-Only flag. To do this, use the following steps.

NOTE : Some programs do not operate correctly with folders that have the System attribute configured. Start Registry Editor (Regedt32.exe). Locate the following registry key:

HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\Current Version\Explorer. On the Edit menu, click Add Value and then add the following registry value:

Value Name: UseSystemForSystemFolders
Data Type: REG_DWORD
Value: 1
Quit Registry Editor.
