It shouldnt because vista does not use any of the sub-keys for itself...
Its clear something has damaged your registry beyond the point of easy repair, try the registry defrag option in Tuneup utilites
TuneUp America - TuneUp Utilities 2008 and the registry cleaner also included.
If its still unresolved after running both registry programs you will have to reinstall vista, if not now sometime very soon as it will only get worse unless you can remove these sub-entrys. Let me know how it works out
