WARNING: Using Registry Editor incorrectly can cause serious, system-wideproblems that may require you to reinstall Windows NT to correct them.Microsoft cannot guarantee that any problems resulting from the use ofRegistry Editor can be solved. Use this tool at your own risk.
When saving the key, instead of clicking the Save Subtree As... option,click the Save Key option from the Registry menu. When trying to restorethe key, click the Restore option from the Registry menu. The saved keywill be restored without error.
The Save Key option saves, as a file, the information contained in aregistry key and in all of its subkeys. A file created using Save Key canbe loaded into the registry (with Load Hive), or can be restored (withRestore). This format is readable by the Registry Editor and should be usedwhen trying to move or save registry keys from one registry to another.
The Save Subtree As... option saves the contents of the currently selectedkey as a text file, including all subkeys and value entries for that key.This format is used to provide a user readable text format for verifyingall of the entries in a key or subkey, and it is not meant to move or saveregistry keys.
