I created fourth partition for Windows 7 Enterprise OS, shrinking voulume of a primary partition of Windows Vista OS, system automatically termed newly created Windows 7 Enterprise OS partion, a 'Logical Drive'.Now ownership of folders and files on Windows 7 Enterprise OS's logical drive, because of Windows automatic updates, changed to system created unknown user. If computer started for Windows 7 Enterprise OS, user logon starts preparation for new owner whose profile doesn't exists, therefore all logon attempts, system restarts.How ownership of folders and files on Windows 7 Enterprise, changed to original user, accessed from primary partitioned Windows Vista?
