Trying to fix the shreg tests

[Paul Vriens]

Hi,

now that the test results are current again :-) I can see why some of
the shreg tests failed before. The error we are getting back for
RegCreateKeyA is ERROR_CHILD_MUST_BE_VOLATILE on most of the XP boxes.

We need to either:

- Use a different key to write to (a non volatile parent)
- Use RegCreateKeyEx instead of RegCreateKey and specify
REG_OPTION_VOLATILE

which one is preferred?

Cheers,

Paul Vriens.
