To solve my update problems (ZASS 10.1 loses expert rules), I read the threads and found many hints like "reformat disk, reinstall Windows".
But isn't this like "if the door is locked: rebuild your house" ?
Especially regarding the effort and time to reinstall not even Windows but drivers, settings, applications and their settings, to search for your license keys of any software, to find the updates for CD-installed software a.s.o.
Shouldn't help you a modern software with messages and logs if an upgrade runs out of control or if something like a database is corrupted ?
Shouldn't the prerequisites of a software upgrade be checked by the installer rather than by the updated itself afterwards ?
