Laut MSKB:
During Windows Millennium Edition setup, Scanreg.exe first copies System.dat, User.dat and Classes.dat if they exist to C:\ as System.new, User.new, and Classes.new. Then it scans the new files and splits or repairs the *.new files as needed. That way it is possible to cancel setup and still have a bootable Windows 95 or Windows 98 system, because the Windows 95 or Windows 98 registry remains unchanged. During setup, Scanreg no longer creates the *.bad backup files of the .dat files as they existed before running setup. Setup now leaves the Classes.1st file hidden at the root of C, along with the System.1st containing the state of the registry before the first boot after setup. |
