This security update resolves a security feature bypass in Microsoft Windows. An attacker could bypass Kerberos authentication on a target machine and decrypt drives protected by BitLocker. The bypass can be exploited only if the target system has BitLocker enabled without a PIN or USB key, the computer is domain-joined, and the attacker has physical access to the computer.
This security update is rated Important for all supported editions of Windows. For more information, see the Affected Software section.
The update addresses the bypass by adding an additional authentication check that will run prior to a password change. For more information about the vulnerability, see theVulnerability Information section.
For more information about this update, see Microsoft Knowledge Base Article 3105256.
I have Windows 8.1 with installed Hyper-V and virtual machines connected via Hyper-V Switch – External. 802.1x wired authentication is not working in host or in guest machine (computer is not responding to switch requests).
If I will change switch mode to Internal/Private it will start working.
Windows 8.1 with a Hyper-V external switch with 802.1x will not work!!!
From https://social.technet.microsoft.com/forums/windows/en-US/341cbe70-3fa7-4991-a7e4-4f1af63df4d0/windows-8-hyperv-8021x-eapol-request-missing i read that “official” statement from Microsoft is that 802.1x with Hyper-V on Windows 8.1 is not working by design. #Fail Microsoft.
Windows 10 will be available on July 29th 2015. Microsoft has prepared for this by already making an Update(KB3058168) that enables Windows 8.1, Windows Server 2012 R2, Windows 8, and Windows Server 2012 Key Management Service (KMS) hosts to activate a “later version of Windows”. This must means Windows 10. I do not know if this means that is even for Windows Server 2016. Windows 10 will be activated by a KMS server running this update but it might.
Select the version you need for the KMS server or servers you use and install them.
All drivers are stored in the so called DriverStore, which is located under %SYSTEMDRIVE%\Windows\System32\DriverStore.
With the built-in command line tool pnputil you can add or remove drivers.
How does it work?
- Start an elevated command prompt (Start, type CMD, hit Ctrl+Shift+Enter)
- Adding a driver:
- Pnputil.exe -a c:\LOCATION_OF_DRIVER\DRIVER_NAME.inf
The location can be either local or remote
- Pnputil.exe -a C:\LOCATION_OF_DRIVER\*.inf
Copy all drivers from that folder
- Deleting a driver:
- Pnputil.exe -d DRIVER_NAME.inf
Windows Server 2012’s System Preparation Tool (sysprep.exe) contains a new switch that allows system administrators to generalize the OS (remove any installation specific configuration) faster than previous versions of the tool that were designed for use on physical hardware.
What’s New in Sysprep for Windows Server 2012?
The new VM-mode method for generalizing a Windows 8 or Server 2012 installation only works from inside a virtual machine. Once sysprep has completed the generalization and shutdown the VM, you can copy the VM’s .vhd file and attach it to a new VM in any system that uses the same hypervisor technology.
Use Sysprep to Generalize Windows Server 2012 Running in a VM
You will need to use sysprep from the command line, as there is no option to enable VM mode in the GUI.
- Install Windows 8 or Windows Server 2012 (or later editions) in a virtual machine.
- Customize the operating system as required.
- Switch to the Start screen and type cmd. Make sure that Command Prompt is highlighted in the search results and press CTRL+SHIFT+ENTER to launch the process with administrative privileges. Give consent or enter credentials if prompted.
- Change the working directory to System32 by typing cd c:\windows\system32\sysprep and pressing Enter.
- To run sysprep with the standard GUI options, but also the /mode:vm switch, type sysprep.exe /oobe /generalize /shutdown /mode:vm and press Enter.
Roaming user profiles on Windows 8-based or Windows Server 2012-based computers are incompatible with roaming user profiles in other versions of Windows.
Profiles are compatible only between the following client and server operating system pairs:
- Windows 8.1 and Windows Server 2012 R2
- Windows 8 and Windows Server 2012
- Windows 7 and Windows Server 2008 R2
- Windows Vista and Windows Server 2008
Note In this article, when the client operating system is referenced, the same issue applies to its corollary server operating system.
For example, if you try to deploy Windows 8 in an environment that uses roaming, mandatory, super-mandatory, or domain default profiles in Windows 7, you experience the following:
- After you use a user account that has an existing Windows 7 profile to log on to a Windows 8-based computer for the first time, the components from Windows 8 read and modify the profile state.
- Certain Windows 8.1 features may not work as expected because the expected profile state is not present.
- When you try to use the same user account to log on to a Windows 7-based computer, the user profile modification that was performed in Windows 8 may not work as expected in Windows 7.
The issues occur because the profile will contain values that are used differently between the versions of Windows. The user profile will be missing default profile configuration information that is expected by the operating system, and could contain unexpected values that are set by a different operating system version. Therefore, the operating system will not behave as expected. Additionally, profile corruption may occur.
To change the network type please do the following:
Hit Winkey + R to open Run prompt and type gpedit.msc
Navigate to: Computer Configuration | Windows Settings | Security Setting | Network List Manager Policies
Choose your Network name from the right pane. In my case network name was wardvissers.local
So the policy look likes
Now we have a Smiley for my wardvissers.local domain Cool!!

This update extends the Key Management Service (KMS) for Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8, and Windows Server 2012 to enable the enterprise licensing of Windows 8.1 and Windows Server 2012 R2.
KMS provides support for the following KMS client activations:
- Windows Vista
- Windows Server 2008
- Windows 7
- Windows Server 2008 R2
- Windows 8
- Windows Server 2012
- Windows 8.1
- Windows Server 2012 R2
KMS uses a KMS host key to activate itself on a KMS host and to establish a local activation service in your environment. This update extends support for KMS to provide activation for Windows 8.1 and for Windows Server 2012 R2.
