     The technology property allows choosing between different drawing APIs and options.
     On most platforms, the only choice is <code>SC_TECHNOLOGY_DEFAULT</code> (0).
-    On Windows Vista or later, <code>SC_TECHNOLOGY_DIRECTWRITE</code> (1),
-    <code>SC_TECHNOLOGY_DIRECTWRITERETAIN</code> (2), or
-    <code>SC_TECHNOLOGY_DIRECTWRITEDC</code> (3)
-    can be chosen to use the Direct2D and DirectWrite APIs for higher quality antialiased drawing.
-    <code>SC_TECHNOLOGY_DIRECTWRITERETAIN</code> differs from
-    <code>SC_TECHNOLOGY_DIRECTWRITE</code> by requesting that the frame
-    is retained after being presented which may prevent drawing failures on some cards and drivers.
-    <code>SC_TECHNOLOGY_DIRECTWRITEDC</code> differs from
-    <code>SC_TECHNOLOGY_DIRECTWRITE</code> by using DirectWrite to draw into a GDI DC.
+    On Windows 7 or later, <code>SC_TECHNOLOGY_DIRECTWRITE</code> (1) performs higher quality antialiased drawing.
+    The other choices in the following table are similar to <code>SC_TECHNOLOGY_DIRECTWRITE</code>
+    but may work or be more efficient in some situations where <code>SC_TECHNOLOGY_DIRECTWRITE</code> fails or is slow.

     On Win32, buffered drawing is set to a reasonable value for the technology: on for GDI and off for Direct2D
     as Direct2D performs its own buffering.
