The Offline Files feature of Windows may be useful for portable computers, but is less useful for desktop workstation PCs. Why Microsoft enables it by default is beyond me.

Among other problems and annoyances, the Offline Files feature can cause problems where files (such as faxes or scans) don't appear in their designated shared folder in a timely fashion.
