It was working only in some Widnows versions.It was taken out
intentionally and is not needed for future development and long term plans.
There would be big delay in everything if Dev would spend all his time now for creating separated anon Windows Xp wallet , Windows Vista wallet, Windows 8 wallet etc...it could harm now the coin
than bringing it up.
If all works well it will be considered again probably.
Multi signature technology is still in place and it is the first coin that has it
Update Your wallets to new versions please
