[win-pv-devel] [PATCH] Make sure registry updates and deletes are flushed

[Paul Durrant <pdurrant@xxxxxxxxx>]

In most cases it is desirable to makre sure any updates are committed to
the registry hive on storage before any further operations are performed.
This patch adds ZwFlushKey() calls to ensure that is the case.
