description:
- A path to a hive key like C:\Users\Default\NTUSER.DAT to load in the
registry.
- This hive is loaded under the HKLM:\ANSIBLE key which can then be used
in I(name) like any other path.
- This can be used to load the default user profile registry hive or any
other hive saved as a file.
- Using this function requires the user to have the C(SeRestorePrivilege)
and C(SeBackupPrivilege) privileges enabled.
version_added: '2.5'
notes:
- Check-mode C(-C/--check) and diff output C(-D/--diff) are supported, so that you can test every change against the active configuration before
applying changes.
- Beware that some registry hives (C(HKEY_USERS) in particular) do not allow to create new registry paths.
- Beware that some registry hives (C(HKEY_USERS) in particular) do not allow to create new registry paths in the root folder.
- Since ansible 2.4, when checking if a string registry value has changed, a case-sensitive test is used. Previously the test was case-insensitive.
