Technology companies are responding to a new Wi-Fi exploit (known as KRACK) affecting all modern Wi-Fi networks using WPA or WPA 2 encryption.
Microsoft says it has already fixed the problem for customers running supported versions of Windows. “We have released a security update to address this issue,” says a Microsoft spokesperson in a statement. “Customers who apply the update, or have automatic updates enabled, will be protected. We continue to encourage customers to turn on automatic updates to help ensure they are protected.”
Microsoft says the Windows updates released on October 10th protect customers, and the company “withheld disclosure until other vendors could develop and release updates.”
The updates are available via Windows update, but if you need to install manually here is the link :-
