  * @param   a_fLocked       For the windows shared folders workarounds.
  *
- * @remarks Disable the PageList feature for 64-bit Windows, because shared
- *          folders do not work, if this is enabled. This should be reenabled
- *          again when the problem is fixed.
- * @remarks Disabled the PageList feature for 32-bit Windows, see xTracker
- *          ticket 6096 and public ticket 10290. Hopefully this is the same
- *          issue as on Windows/AMD64.
+ * @remarks Disabled the PageList feature for locked memory on Windows,
+ *          because a new MDL is created by VBGL to get the page addresses
+ *          and the pages from the MDL are marked as dirty when they should not.
