Where is Group Policy Preference for Internet Explorer 11 ?

After joining the Windows 8.1 enterprise into domain environment, I was expecting that GPMC will introduce new GPP template for Internet Explorer 11, but the latest version was still the Internet Explorer 10.
So, how to apply settings to Internet Explorer 11 via GPP ?
Fortunately, GPP for Internet Explorer 10 will also work with Internet Explorer 11. Why ?
I opened GPP for IE10 xml file, and saw that file version filtering for iexplore is between 10 and 99.
Here is the filtering part from the xml file:

path="%ProgramFilesDir%\Internet Explorer\iexplore.exe" type="VERSION" gte="1" min="10.0.0.0" max="99.0.0.0"

My opinion is that with this kind of file filter versioning for iexplore, the GPP template should be named Internet Explorer 10 and higher, not just Internet Explorer 10.

KMS activation of Windows 8.1 and Windows Server 2012 R2

In order to activate Windows 8.1 and Windows Server 2012 R2 using KMS hosted on previous generation of Windows operating system, Microsoft has published following kb article http://support.microsoft.com/kb/2885698/en-us .
After installing the update, you will be able to install and activate your KMS key for Windows 8.1 and (or) Windows Server 2012 R2.
Procedure for installing the KMS host key is the same as installing KMS host key from previous versions of Windows operating systems:

cscript %windir%\system32\slmgr.vbs /ipk <KMS host key>

You will experience following error if you are installing KMS host key on Windows operating system that is not associated with that host key:

0xc004f015: The Software Licensing Service reported that the license is not installed. SL_E_PRODUCT_SKU_NOT_INSTALLED

 For example:

• Windows 7 KMS host key install on Windows Server 2008 R2
• Windows 8 KMS host key install on Windows Server 2008 R2, Windows Server 2012
• Windows 8.1 KMS host key install on Windows Server 2008 R2, Win Server 2012 and R2

 Activate the KMS host key using:

cscript %windir%\system32\slmgr.vbs /ato

In my case the KMS server was using proxy for connecting to internet and the user activating the KMS host key was not having proper permission to access the Microsoft's Internet Activation Servers. The activation was failing with following error message 0x8004FE92:

On a computer running Microsoft Windows non-core edition, run 'slui.exe 0x2a 0x8004FE92' to display the error text. Error: 0x8004FE92

Running the 'slui.exe 0x2a 0x8004FE92' does not provide a lot of help:

 

After providing proper Internet access for the user, activating the KMS host key has completed successfully. More about 0x8004FE92 error message can be found on http://support.microsoft.com/kb/2009934/en-us .

 

Folder redirected offline folders out of sync

A colleague of mine on his Windows 7 client workstation was complaining about his profile redirected offline folders that were out of sync with folders that were residing on file server. He tried almost everything to get those files and folders in sync, so finally last chance to rescue was to reset offline database and re-initialize the cache of offline files.
In order to do that, following registry entry has to be created:

FormatDatabase  DWORD (32 bit value) : 1

in

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\CSC\Parameters

After rebooting the client, redirected offline folders started to work as expected.

Note: Before taking this action please make backup of your files, because unsynchronized changes will be lost.

Unable to delete VHD from VMM library

While browsing the VMM 2012 SP1 library, I found an obsolete VHD, and I wanted to delete it from there. But, when I tried to delete this obsolete VHD, VMM was complaining with following error message:

The library object (Name of the VHD) cannot be removed because following objects are dependent on it:

Virtual Hard Disk deployment configuration

In order to delete this VHD from VMM library I have opened table tbl_WLC_VHDConfig from VM database using SQL Management Studio. In this table there is a column named "SourceLocation". In this column we can find the ID of the offending VHD. But how to find the ID of VHD ? Using Get-VirtualHardDisk cmdlet you can list all the VHDs with their IDs:

Get-VirtualHardDisk | ft name,id

Now when we have the ID of the VHD, we can create new query from SQL Management Studio to delete the row containing VHD ID in SourceLocation column:

Delete From dbo.tbl_WLC_VHDConfig Where SourceLocation = 'VHD ID'

Note: Make a backup of the VM database before changing (deleting) rows from database, and this operation is not recommended by Microsoft, so perform at your own risk.
