I have been using Windows 2003 for a long time. There is a wonderful feature. I don't know the name of it but the feature is like this. You can rename or delete some important files inside C:\windows\system32. e.g. kerberos.dll. After a while, the deleted files will be automatically recovered. I think this is because those files are criticl enough that Windows cannot survive without them.

However, in Windows 2008, this feature is gone. Instead, all the files in System32 are owned by TrustedInstaller. However, as a administrator, I can still take the ownserhip of the files and then delete them. Windwos 2008 won't recover the deleted files and hence the system is screwed next time it's reboot.

So, I wonder why Windows 2008 dropping that wonderful feature. Was that auto-recovery feature also suffer from some issues? Does Windows 2008 have some other features that can prevent this type of disaster from happening?
