Windows has a Font Cache service that runs in the background so I would imagine they do. I'm not a Desktop Developer so I'm not all that familiar with the Windows API. But like any system, just because a convenient API exists that doesn't mean developers know about or use it. Especially with cross platform solutions, developers will opt not to use a particular API because it complicates things. My guess is that these are poorly optimized Apps and the blogger is blaming the OS for their offenses.
