I was recently in a position where I needed help to get a banking password back, I called tech help, and they told me to delete my browser history I was hesitant but told it would be OK.
Not so. I got my bank password, but now I am locked out of absolutely everything else
Including my primary emails as I used a software to remember passwords(did not help with the bank one) so I have lost all my contacts I am elderly and not very techy to start with!
Help please, I have lost contact with family everything...

PS I googled in for help on this and answers did not help at all...

Basically your busted.
If you "used a software to remember passwords" what has happened to that ?

Once you delete the history its gone but only way to restore it is to restore your windows to the last backup access point
