First at all; thank you for your answers.
In the article, microsoft wrote: "Die hier beschriebene Vorgehensweise garantiert keine vollständige Wiederherstellung des Systems in seinem früheren Zustand", that means in my opinion, that there is no guaranty to get a previous system back in original function. Only the handling of data will be o.k.
After restauration, i thing it makes no sence to go to the system control panel to restore a previous restauration point, to reinstall jv16 and restore the backup file in the registry cleaner. Or will this work?
Is there no other possibility to get back the jv16 backup in the existing registry????? (XP-console??)
Thank's
