+#  Credential Guard: Known issues 
+
+**Applies to**
+-   Windows 10
+-   Windows Server 2016
+ 
+Credential Guard has certain requirements for applications. Credential Guard blocks specific authentication capabilities. Therefore applications that require such capabilities will not function when Credential Guard is enabled. For further information, see [Application requirements](https://docs.microsoft.com/en-us/windows/access-protection/credential-guard/credential-guard-requirements#application-requirements).
+
+The following known issues have been fixed by servicing releases made available in the Cumulative Security Updates for April 2017:
+
+•	KB4015217: [Credential Guard generates double bad password count on Active Directory domain-joined Windows 10 machines](https://support.microsoft.com/en-us/help/4015217/windows-10-update-kb4015217)
+
+This issue can potentially lead to unexpected account lockouts.
+See also Knowledge Base articles [KB4015219](https://support.microsoft.com/en-us/help/4015219/windows-10-update-kb4015219) and 
+[KB4015221](https://support.microsoft.com/en-us/help/4015221/windows-10-update-kb4015221).
+
+In addition, products that connect to Virtualization Based Security (VBS) protected processes can cause Credential Guard-enabled Windows 10 clients to exhibit high CPU utilization. For further information, see the following Knowledge Base articles:
+
+•	KB88869: [Windows 10 machines exhibit high CPU usage with McAfee Application and Change Control (MACC) installed when Credential Guard is enabled](https://kc.mcafee.com/corporate/index?page=content&id=KB88869)
+
+•	[Installing AppSense Environment Manager on Windows 10 machines causes LsaIso.exe to exhibit high CPU usage when Credential Guard is enabled](http://www.appsense.com/kb/160525073917945) *

 ## Enable Credential Guard
 Credential Guard can be enabled either by using [Group Policy](#enable-credential-guard-by-using-group-policy), the [registry](#enable-credential-guard-by-using-the-registry), or the Device Guard and Credential Guard [hardware readiness tool](#hardware-readiness-tool). Credential Guard can also protect secrets in a Hyper-V virtual machine, just as it would on a physical machine.
