Registry keys like C<CurrentControlSet> don't really exist in the
Windows Registry at the level of the hive file, and therefore you
-cannot modify these. Replace this with C<ControlSet001>, and
-similarly for other C<Current...> keys.
+cannot modify these.
+
+C<CurrentControlSet> is usually an alias for C<ControlSet001>. In
+some circumstances it might refer to another control set. The way
+to find out is to look at the C<HKLM\SYSTEM\Select> key:
+
+ # virt-win-reg WindowsGuest 'HKLM\SYSTEM\Select'
+ [HKEY_LOCAL_MACHINE\SYSTEM\Select]
+ "Current"=dword:00000001
+ "Default"=dword:00000001
+ "Failed"=dword:00000000
+ "LastKnownGood"=dword:00000002
+
+"Default" is the one which Windows will choose when it boots.
+
+Similarly, other C<Current...> keys in the path may need to
+be replaced.
