Sorry, how the boot speed is connected with security? Registry keys are protected by ACLs. You cannot achieve better protection with files. >A folder with > separate files for each program/service would not only be faster but Will be slower. Each file should be opened. Dirent read+metadata read+data read. Several seeks. Registry is read linearly in 64KB chunks on boot. All parsing is done in memory. > would help with the security problems as well. No. For instance, there is FAT filesystem with no ACLs on files. Registry is still protected. Not to say that "many files" approach hardens the "backup system state" task a lot. -- Maxim Shatskih, Windows DDK MVP StorageCraft Corporation maxim@storagecraft.com http://www.storagecraft.com
