Core Refuses to allow Delete of Reg Keys

[cumbres]

When using the Registry cleaner I am told that about 18 registry entries can not be removed because Windows Core doesn't allow it. I have shown a few of the errors below. Can anyone help? I have uninstalled this program (quicktime). I don't know what else to do to get these keys deleted.

Thanks!

You could try changing permissions with RegEdit.

See if it lets you give your userid "Full control" for the HKEY_CLASSES_ROOT\QuickTime.qhtm key.

If it does, Windows core might let PowerTools remove those entries.

I did the permissions trick without success. I finally got brave and used Regedit to delete the offending items. It did it without problem. Now everything is fine. But I still don't know what was so special about those keys that JV16 couldn't get them.
