Ronny,
Windows XP SP1 contains a registry resiliency feature to automatically delete corrupted registry keys when Windows starts, and when a user hive is loaded when a user logs on or loads a hive with Registry Editor. If you want to troubleshoot the cause of the registry corruption, you cannot collect the corrupted registry before Windows tries to fix it.

I get the following message at boot-up:
"Windows Registry Recovery"
One of the files containing the System's Registry data had
to be recovered by use of a log or alternate copy. The
recovery was successful."
How do I correct it?
