FileFontStrike contains a check as to whether the current Windows version is Windows XP or later. The current minimum supported version is Windows 10, so this is no longer needed.

When the code in question was added 17 years ago, a test was included (test/jdk/java/awt/Graphics2D/DrawString/ScaledLCDTextMetrics.java), so this can be used to verify that there are no regressions.
