Since the registry is quite sensitive to corruption, it is very
advisable to backup from time to time. Unfortunately, this is not
the case with Windows versions based on the NT kernel. In Windows XP
it is backed up only as part of the bloated and resource hogging
System Restore program which cannot even be used for a "restore"
should a corrupted registry prevent Windows from booting. It
has also become impossible to copy the necessary files, now called
"hives" and usually named DEFAULT, SAM, SECURITY, SOFTWARE, SYSTEM
in the SYSTEM32\CONFIG folder, to another location because they
are all in use by the OS. And though the registry in an NT-based
Windows is less likely to become corrupted than in other versions,
it
can still happen, and for these cases NT is simply missing an option
for easy registry backup and restore as there is in Windows 9x/Me,
to
get the system up and running again in no time.
This program offers the ease-of-use of Windows 9x/Me ERU by
Microsoft (hence the name ERUNT) to backup the registry, as well as
providing an auto-backup capability, for example at Windows startup.
Or, before installing a new program for testing purposes one could
save the registry with ERUNT, install and test the program,
uninstall
it and restore the registry to be 100% sure that no debris is left.
Note: The "Export registry" function in Regedit is USELESS (!) for
making a complete backup of the registry. Neither does it export the
whole registry (for example, no information from the "SECURITY" hive
is saved), nor can the exported file be used later to replace the
current registry with the old one. Instead, if you re-import the
file,
it is merged with the current registry without deleting anything
that
has been added since the export, leaving you with an absolute mess
of
old and new entries. |
