Just wanted to bring this to the attention of Farbar or whoever else helps develops Farbar Service Scanner (FSS) that LEGACY_Dnscache
is only valid in Windows XP Systems (maybe Windows 2000 / ME / 98 / 95 too).
Referring to this key: hklm\system\currentcontrolset\enum\root\LEGACY_DNSCACHE
I had someone running a Windows Vista system run FSS and it reported that this key is missing. Here is the actual log
if you wanted to see it yourself.
I understand this tool is always under construction and as always keep up the great work
