How to stop Windows 10 from sharing your WiFi password

“When you share Wi-Fi network access with Facebook friends, contacts, or Skype contacts, they’ll be connected to the password-protected Wi-Fi networks that you choose to share and get Internet access when they’re in range of the networks (if they use Wi-Fi Sense). Likewise, you’ll be connected to Wi-Fi networks that they share for Internet access too. Remember, you don’t get to see Wi-Fi network passwords, and you both get Internet access only. They won’t have access to other computers, devices, or files stored on your home network, and you won’t have access to these things on their network.”

WiFi Sense will automatically connect you to detected crowdsourced WiFi networks, acquire network information and provide “additional info” to networks that require it (it’s not clear exactly what constitutes additional info), and can be used to automatically share your WiFi password with your contacts on Facebook, Skype, and Outlook.

On a practical level, the risks from WiFi Sense are small. But from a best-practices security standpoint, it’s far from a great idea.

Oh, my God, disable NOW:

Settings->Manage WiFi Settings->Wi-Fi Sense

Turn it off

Windows 10 Code Integrity and Cryptographic problems, EventID: 513

Description: Cryptographic Services failed while processing the OnIdentity() call in the System Writer Object

The Code Integrity component of Windows enforces the requirement that kernel-mode drivers be signed in order to load. Windows always generate Code Integrity operational events and optionally will generate additional system audit events and verbose diagnostic events that provide information about the status of driver signing.
The Code Integrity operational log includes warning events that indicate that a kernel-mode driver failed to load because the driver signature could not be verified. Signature verification can fail for the following reasons:
An administrator preinstalled an unsigned driver, but Code Integrity subsequently blocked loading the unsigned driver.
The driver is signed, but the signature is invalid because the driver file has been altered.
The system disk device might have device errors when reading the file for the driver from bad disk sectors.
