This is seriously strange.
I am now using IE10 - having had 8 and 9 as secondary browsers.
Credential manager only shows passwords from MS sites - Outlook, Live etc.
Password revealers show nothing.
The old Password Storage api is no longer used.
The registry keys HKCU or KHLM Software/Microsoft/IE/Intelliforms........ show only two (encrypted) keys - I assume they are for Outlook and Live.
Yet IE10, even though cookies are blocked from individual sites, remembers my logins from VV, Tinypic, BBC - they are blocked to test thing. It is saving logins somewhere, but nobody knows where! MS ain't letting on.
I have cleared things using both our methods, Suff, to no avail. I simply cannot find a way of recovering lost password pairs and it is driving me nuts.
