I have been trying to use Eriks philosophy of using a Frozen Snapshot, but trying to make it as easy to use for everyday usage. The main problem AFAICS with using a frozen snapshot is that program settings/data are not saved and always revert back to the frozen settings/data on reboot. Because of this I've been moving all data/settings to a separate partition where possible. However, I have run into a problem with using Kaspersky Anti-Virus 6. It's possible to move most of the settings to a separate partition, but it's not possible to move four data files (used for determining if files have already been scanned) which reside in the system32\drivers folder. This location is currently hard-coded by Kaspersky so I have made a feature request to allow them to be moved. In the mean time, I tried to Data anchor these four files but FD-ISR won't allow me to. I can understand why it's normally a bad idea to data anchor any files/folder in the WINDOWS folder and below, but don't understand why there is no way to over-ride this limitation (eg. an option "Allow data anchoring of sensitive folders" which is disabled by default) to allow data anchoring if the user needs to. This is another case of bad design where you limit what the user can do for good reason, without giving them the option to over-ride when required. This makes it hard to work with the Frozen Snapshot philosophy for day-to-day usage, at least when using KAV 6.
