Do not preserve zone information in file attachments This policy setting lets you manage whether Windows marks file attachments that have information about their zone of origin. These zones or origin are Internet, intranet, and local. This policy setting requires the NTFS file system to function correctly and will fail without notice on systems that use FAT32. By not preserving the zone information, Windows cannot make appropriate risks assessments. If you enable this policy setting, Windows does not mark file attachments by using their zone information. If you disable this policy setting, Windows marks file attachments by using their zone information. If you do not configure this policy setting, Windows marks file attachments by using their zone information. Group Policy User Configuration\Administrative Templates\Windows Components\Attachment Manager Registry Subkey HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Attachments Registry Entry SaveZoneInformation Entry Value On (1) or Off (2)So, what value is needed to be set? Positive or negative logic? The "entry value" refers to "policy setting" or "registry entry"?
The main thing that raised my suspicion is that I discovered I had originally set the value to 2 (a couple of years ago - yeah, without reinstall ) and never ever seen the warning. I searched the whole registry and found it on two places - both were set to 2). And although I use so many reg tweaks I can't keep track of them any more, the LowRiskFileTypes tweak, which often acompanies this one, is not present on my computer. If it's another (which is quite possible), which one?
And as I said, the only critical opinion on this tweak was this one (yeah, old threads are useful too), but the values aren't right, so again I'm suspicious.
As I don't have the energy to fire up a virtual machine and install XP SP2 or 3 to do the testing (but will do later on if necessary), I'm asking for any further meaningful info on the subject.
