System information

System Contains Windows NT setup information, a control set for each
found system configuration and the current control set with the
current configuration values.
In the hardware and software branch of the tree, you normally don′t have to edit
entries. These are made through the installation and configuration program. In
the software branch you might found some values that can be changed manually
to alter the settings for an application.
Please consult the Help function to get more information about adding keys,
adding or editing values and the different value types. Make sure you enter
values in the right format.
2.2.6.1 Backup and Restore the Registry
Within the Registry Editor, you can save every key with its subkeys to a file
except the Security key, were only the system has the rights to access. You can
not save entire hives.
With the restore function of the Registry Editor, Keys with its subkeys can be
restored to its original hive as long as the active key is not in use. Open Keys
can not be overwritten.
The Registry function of backup and restore is suitable to save individual keys
for backup reasons or to use them on other systems. You can not use it to back
up the whole system configuration. For this, there are two possibilities:
•
Back up the system with the Windows NT Tape Backup program to a tape
drive. This will back up the registry hives even when they are in use. Also
the restore task will override the active registry. The restores registry
entries will be active after rebooting the system.
•
If you don′t have a tape drive or not want to use it, there are tools delivered
with the Windows NT Resource Kit to back up (REGBACK.EXE) and restore
(REGREST.EXE) entire hives. There are also more tools to handle the
registry. See 2.3, “System Management Tools Provided by Windows NT
Resource Kit” on page 74 about using the NT Resource Kit.
