Windows 8 Client Hyper-V copy/paste
A new feature within Windows 8 is Client Hyper-V. So within our Client OS you can run Hyper-V, that’s cool!! When you want to copy and paste some text, for example a script, this is not that easy as drag and drop or copy/paste! Is it possible? Yes, absolutely!!
The thing you need to do is copy the text on your local system, navigate back to your quest machine (VM), select the clipboard tab and hit Type clipboard text. Now you text is copied from the local machine into your quest machine!

RES Workspace Manager 2012 Recent Files not vissible in start menu
A copple of months ago I have configured a new Citrix XenApp 6.5 with RES Workspace Manager 2012 environment. Within this environment I have configured mandatory profiles, added to Workspace Manager as a custom resource.
When the user are opening some documents, the Recent Files folder is filled up with the last opened document. The save location is C:\Users\%username%\AppData\Roaming\Microsoft\Windows\Recent.
I’ve created a new User Setting to save the content within this folder. Now there is something strange happening!! The content is saved within a UPF (User Preference File) correctly, but its not vissible in the user session from the start menu.
When I open a commandline and browse to my user profile, the content is there! Huh…?!? After some troubleshooting, I have figured out that I had to change one setting within my custom resource. The folder AppData\Microsoft\Windows\Recent was marked as Read-Only. That’s the problem! After disabling the Read-Only, the recent files are vissible from my start menu.

How to: Enable data deduplication in Windows Server 2012
A very cool new feature within Windows Server 2012 is Data Deduplication. Windows will look on block level to duplicate files and removes this files with pointers to the duplicate files. This can save you a lot of diskspace! Data Deduplication can be enabled on all the volumes of your server, except the boot volume!
By default, Data Deduplication will only deduplicate data that is not changed over the last 30 days. You can change this value to any numbers of days you want. Lets enable Data Deduplication. After enabling Data Deduplication, there are three scheduled tasks available (only vissible through PowerShell).
In my example I’ve copied the Windows Server 2012 ISO three times to my ISO partition. So there are three folder called ISO1, ISO2 and ISO3. All the folder contains exact the same data. So three times the ISO files are around the 10 GB of storage on my disk. Watch the result after enabling this great new feature….do you have any idea?? 
1.) Open the Server Manager and enable Data Deduplication on the File and Storage Services server role.
2.) Or open PowerShell and enable this rol
Import-Module ServerManager
Add-WindowsFeature -name FS-Data-Deduplication
3.) Enable Deduplication on the specific volume or volumes
Import-Module Deduplication
Enable-DedupVolume E:
4.) View the new scheduled Deduplication jobs
Get-DedupSchedule
5.) Change the MinimumFileAgeDays value to 0
Set-DedupVolume E: -MinimumFileAgeDays 0
6.) Start the Deduplication jobs manualy
Start-DedupJob E: -Type Optimazation
Start-DedupJob E: -Type GarbageCollection
Start-DedupJob E: -Type Scrubbing
7.) After a few minutes, watch the result!
Get-DedupStatus
How cool is that. Are you also going to enable Data Deduplication?

How to: Enable Jumbo frames on your ISCSI network interface using PowerShell
When building an Windows Server 2012 Hyper-V environment, you want to automate some steps on all the cluster nodes. One of this steps is definitely enabling Jumbo frames on your ISCSI interface(s). You can do this on the properties of you NIC interface, but when you’re installing Hyper-V 2012 Server…YES, there’s no GUI.
The great thing is that there is something called PowerShell . You can configure Jumbo frames using PowerShell.
1.) Open PowerShell
2.) Generate an overview of all the Network Interfaces in your Hyper-V host
Get-NetAdapter | ft Name
In my labenvironment there are two ISCSI interfaces (ISCSI01 and ISCSI02)
3.) Show the advanced NIC properties of the ISCSI interfaces
Get-NetAdapterAdvancedProperty -name ISCSI01
Get-NetAdapterAdvancedProperty -name ISCSI02
As you can see, Jumbo Packet is Disabled
4.) Configure the most common Jumbo Frame setting of 9014 bytes. Note that not all SAN’s supports this value.
Set-NetAdapterAdvancedProperty -Name ISCSI01 -RegistryKeyword “*JumboPacket” -Registryvalue 9014
Set-NetAdapterAdvancedProperty -Name ISCSI02 -RegistryKeyword “*JumboPacket” -Registryvalue 9014
5.) Now Jumbo frames is enabled
Get-NetAdapterAdvancedProperty -name ISCSI01
Get-NetAdapterAdvancedProperty -name ISCSI02
