RegDelNull

Question

Hello,

I have a COMPONENTS hive that has a key including null characters. I have tried using the RegDelNull tool to delete this key, and it does find the problem, but fails to repair. Is this caused by the fact that the COMPONENTS hive is separate? I have tried everything I can find and I'm unable to delete this key. Is there a special syntax or switch to use to get past this? Note the snapshot below:

Hello John Ivey,

Thank you for posting in Q&A forum.

The -s option in RegDelNull is used to recurse into subkeys. Here's a sample command that demonstrates how to use it:

regdelnull HKEY_LOCAL_MACHINE\SOFTWARE\ExampleKey -s

I hope the information above is helpful.

If you have any questions or concerns, please feel free to let us know.

Hello Daisy,

I used that parameter in the screenshot I posted, but it makes no difference. I believe this is an issue with the way RegDelNull handles registry hives, and it needs to be updated to correct this error.
