 ## Wi-fi and VPN Considerations
+
 When you enable Windows Defender Credential Guard, you can no longer use NTLM classic authentication for Single Sign-On. You'll be forced to enter your credentials to use these protocols and can't save the credentials for future use. If you're using WiFi and VPN endpoints that are based on MS-CHAPv2, they're subject to similar attacks as for NTLMv1. For WiFi and VPN connections, Microsoft recommends that organizations move from MSCHAPv2-based connections such as PEAP-MSCHAPv2 and EAP-MSCHAPv2, to certificate-based authentication such as PEAP-TLS or EAP-TLS.

 When you enable Windows Defender Credential Guard, you can no longer use Kerberos unconstrained delegation or DES encryption. Unconstrained delegation could allow attackers to extract Kerberos keys from the isolated LSA process. Use constrained or resource-based Kerberos delegation instead.
 
 ## 3rd Party Security Support Providers Considerations
+
 Some 3rd party Security Support Providers (SSPs and APs) might not be compatible with Windows Defender Credential Guard because it doesn't allow third-party SSPs to ask for password hashes from LSA. However, SSPs and APs still get notified of the password when a user logs on and/or changes their password. Any use of undocumented APIs within custom SSPs and APs aren't supported. We recommend that custom implementations of SSPs/APs are tested with Windows Defender Credential Guard. SSPs and APs that depend on any undocumented or unsupported behaviors fail. For example, using the KerbQuerySupplementalCredentialsMessage API isn't supported. Replacing the NTLM or Kerberos SSPs with custom SSPs and APs.

 ## Upgrade Considerations
+
 As the depth and breadth of protections provided by Windows Defender Credential Guard are increased, subsequent releases of Windows 10 with Windows Defender Credential Guard running may impact scenarios that were working in the past. For example, Windows Defender Credential Guard may block the use of a particular type of credential or a particular component to prevent malware from taking advantage of vulnerabilities. Test scenarios required for operations in an organization before upgrading a device using Windows Defender Credential Guard.
 
 ### Saved Windows Credentials Protected
 
-Starting with Windows 10, version 1511, domain credentials that are stored with Credential Manager are protected with Windows Defender Credential Guard. Credential Manager allows you to store three types of credentials: Windows credentials, certificate-based credentials, and generic credentials. Generic credentials such as user names and passwords that you use to log on to websites aren't protected since the applications require your cleartext password. If the application doesn't need a copy of the password, they can save domain credentials as Windows credentials that are protected. Windows credentials are used to connect to other computers on a network. The following considerations apply to the Windows Defender Credential Guard protections for Credential Manager:

 * Windows credentials saved by Remote Desktop Client can't be sent to a remote host. Attempts to use saved Windows credentials fail, displaying the error message "Logon attempt failed."
 * Applications that extract Windows credentials fail.
 * When credentials are backed up from a PC that has Windows Defender Credential Guard enabled, the Windows credentials can't be restored. If you need to back up your credentials, you must do this before you enable Windows Defender Credential Guard. Otherwise, you can't restore those credentials.

 ### Windows credentials saved to Credential Manager
+
 Since Credential Manager can't decrypt saved Windows Credentials, they're deleted. Applications should prompt for credentials that were previously saved. If saved again, then Windows credentials are protected Credential Guard.
 
 ### Domain-joined device’s automatically provisioned public key
+
 Beginning with Windows 10 and Windows Server 2016, domain-devices automatically provision a bound public key, for more information about automatic public key provisioning, see [Domain-joined Device Public Key Authentication](/windows-server/security/kerberos/domain-joined-device-public-key-authentication).
 
 Since Credential Guard can't decrypt the protected private key, Windows uses the domain-joined computer's password for authentication to the domain. Unless additional policies are deployed, there should not be a loss of functionality. If a device is configured to only use public key, then it can't authenticate with password until that policy is disabled. For more information on Configuring devices to only use public key, see [Domain-joined Device Public Key Authentication](/windows-server/security/kerberos/domain-joined-device-public-key-authentication).

 #### Impact of DPAPI failures on Windows Information Protection
+
 When data protected with user DPAPI is unusable, then the user loses access to all work data protected by Windows Information Protection.  The impact includes: Outlook 2016 is unable to start and work protected documents can't be opened.  If DPAPI is working, then newly created work data is protected and can be accessed.
 
 **Workaround:** Users can resolve the problem by connecting their device to the domain and rebooting or using their Encrypting File System Data Recovery Agent certificate. For more information about Encrypting File System Data Recovery Agent certificate, see [Create and verify an Encrypting File System (EFS) Data Recovery Agent (DRA) certificate](/windows/threat-protection/windows-information-protection/create-and-verify-an-efs-dra-certificate).
