In Windows 8 You can configure IE10 to always open in the default Metro style or in Internet Explorer for the Desktop, as you prefer.
To configure the way links display in IE10 when you open them:
- If you are using a Metro version of IE, when viewing a site in IE10, click Page Tools and select View on the desktop.
- Click Tools, and select Internet options.
- Click to display the Programs tab.
- In the Opening Internet Explorer section, select the default option you desire from the menu, and then click OK.
There are 3 IE launch options.
Let Internet Explorer decide
This option will choose which version of IE to open depending on the context where the link was selected. Selecting a link from a Metro style-app will open the touch-optimized version of the browser. Selecting a link from an application or icon on the desktop will open the desktop version of the browser. This option is the default.
Always in Internet Explorer
Links from all apps, including desktop apps, will open in Metro version of IE. The only exception here is IE icons and Internet shortcuts on the desktop.
Always in Internet Explorer on the desktop
Links from all apps, including Metro style-apps, will open Desktop version of IE.
When you install Windows Server 2012, you can choose between Server Core Installation and Server with a GUI. The Server with a GUI option is the Windows Server 2012 equivalent of the Full installation option available in Windows Server 2008 R2. The Server Core Installation option reduces the space required on disk, the potential attack surface, and especially the servicing requirements. In Windows Server 2012, you can freely switch between these options at any time, one approach might be to initially install the Server with a GUI option, use the graphical tools to configure the server, and then later switch to the Server Core Installation option.
To use PowerShell to switch between Server Core and Full Server with GUI
Full Server with GUI to Server Core
Uninstall-WindowsFeature Server-Gui-Mgmt-Infra -Restart
Server Core to Full Server with GUI

Windows 7 introduced Native VHD boot which allows user to install Windows 7/Windows server 2008 R2 on a physical box to a virtual hard disk (VHD). You can do same process in Windows 8
- Boot from the Windows 8 media (USB, CD, etc.).
- At the Install screen, press Shift+F10 to open a command prompt.
- Start diskpart and create the VHD file you want to install to:
create vdisk file=c:win8.vhd maximum=80000 type=expandable
select vdisk file=c:win8.vhd
create partition primary
format fs=ntfs label=”Win8″ quick
- Exit diskpart, and when you install Windows 8 you’ll be able to select your VHD volume (ignore the warning that you won’t be able to install).
If this is an existing machine, and you want to dual boot rather than wipe the disk, then don’t perform the first three blocks of commands.
Windows 8 supports virtualization on the client OS to allow IT professionals and developers to use Hyper-V as a desktop operating system. If you are an IT Professional or developer that uses Windows Server as development operating environments, you should be excited about new client Hyper-V feature in Windows 8 and wonder what are some of the key differences and similarities between Windows 8 Hyper-V and Windows Server 2012 Hyper-V?
Here are the some of the key differences in Windows 8 Client Hyper-V from Windows Server 2012 Hyper-V:
- No Hyper-V Replica
- No Hyper-V Network Virtualization
- No Virtual Machine Live Migration (Requires Failover Clustering only in Windows Server)
- No Shared Nothing Live Migration
- No SR-IOV (You need server class hardware; appropriate firmware, etc; you won’t find this on desktops)
- No Failover Clustering (Client doesn’t include Failover Clustering)
- No Virtual Fiber Channel
- No RemoteFX GPU Hardware Acceleration ( which requires RDV only in Windows Server)
- Second Level Address Translation (SLAT) HW required
And the commonalities between Windows 8 Hyper-V & Windows Server 2012 Hyper-V
- Virtual Machines created with Client Hyper-V are 100% compatible with Server Hyper-V
- Client Hyper-V offers the same VM scale as Server
- Up to 64 virtual processes per VM
- Up to 64TB per virtual disk ( vhdx format )
- Up to 1 TB of memory per VM.
- Live Storage Migration is included
- Support VHD Storage on SMB3 file shares
- 100% PowerShell/WMI compatibility in management from Client to Server.
- Client Hyper-V offers the full rich, open and extensible Hyper-V virtual switch.
- QoS, bandwidth management and other advanced virtual switch capabilities are in there
