Microsoft Virtual Machine Converter 3.0 Released

New Features in Microsoft Virtual Machine Converter 3.0
The 3.0 release of MVMC adds the ability to convert a physical computer running Windows Server 2008 or above server operating systems or Windows Vista or above client operating systems to a virtual machine running on Hyper-V host.

Standard stuff is:

  • Converts virtual disks that are attached to a VMware virtual machine to virtual hard disks (VHDs) that can be uploaded to Microsoft Azure.
  • Provides native Windows PowerShell capability that enables scripting and integration into IT automation workflows.
    Note The command-line interface (CLI) in MVMC 1.0 has been replaced by Windows PowerShell in MVMC 2.0.
  • Supports conversion and provisioning of Linux-based guest operating systems from VMware hosts to Hyper-V hosts.
  • Supports conversion of offline virtual machines.
  • Supports the new virtual hard disk format (VHDX) when converting and provisioning in Hyper-V in Windows Server® 2012 R2 and Windows Server 2012.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.1, and VMware vSphere 4.1 hosts Hyper-V virtual machines.
  • Supports Windows Server® 2012 R2, Windows Server® 2012, and Windows® 8 as guest operating systems that you can select for conversion.
  • Converts and deploys virtual machines from VMware hosts to Hyper-V hosts on any of the following operating systems:
  • Windows Server® 2012 R2
  • Windows Server® 2012
  • Windows Server 2008 R2 SP1
  • Converts VMware virtual machines, virtual disks, and configurations for memory, virtual processor, and other virtual computing resources from the source to Hyper-V.
  • Adds virtual network interface cards (NICs) to the converted virtual machine on Hyper-V.
  • Supports conversion of virtual machines from VMware vSphere 5.5, VMware vSphere 5.0, and VMware vSphere 4.1 hosts to Hyper-V.
  • Has a wizard-driven GUI, which simplifies performing virtual machine conversions.
  • Uninstalls VMware Tools before online conversion (online only) to provide a clean way to migrate VMware-based virtual machines to Hyper-V.
    Important MVMC takes a snapshot of the virtual machine that you are converting before you uninstall VMware Tools, and then shuts down the source machine to preserve state during conversion. The virtual machine is restored to its previous state after the source disks that are attached to the virtual machine are successfully copied to the machine where the conversion process is run. At that point, the source machine in VMware can be turned on, if required.
    Important MVMC does not uninstall VMware Tools in an offline conversion. Instead, it disables VMware services, drivers, and programs only for Windows Server guest operating systems. For file conversions with Linux guest operating systems, VMware Tools are not disabled or uninstalled. We highly recommend that you manually uninstall VMware Tools when you convert an offline virtual machine.
  • Supports Windows Server and Linux guest operating system conversion. For more details, see the section “Supported Configurations for Virtual Machine Conversion” in this guide.
  • Includes Windows PowerShell capability for offline conversions of VMware-based virtual hard disks (VMDK) to a Hyper-V–based virtual hard disk file format (.vhd file).
    Note The offline disk conversion does not include driver fixes.

Performance issues or delays when you connect to Exchange Server 2013 that is running in Windows Server

Microsoft released a new KB article about a performance issue with Exchange 2013

When you connect to a Microsoft Exchange Server 2013 server that is installed in Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, or Windows Server 2008 in which Microsoft .NET Framework 4.5 is included, you may experience delays to access email messages or disconnections to the Exchange server. When this issue occurs, the CPU or memory usage on the server is high for some services that include one or more of the W3wp.exe processes.

This issue occurs because too many objects are pinned on the .NET Framework 4.5 garbage collector heap. It causes heap fragmentation in addition to an increase in CPU and memory usage by the garbage collector.

Important Follow the steps in this section carefully. Serious problems might occur if you modify the registry incorrectly. Before you modify it, back up the registry for restoration in case problems occur.

For Exchange Server 2013 that is installed in Windows Server 2012

Apply hotfix 2803755 that needs a restart, and then use one of the following methods to enable the hotfix:

  • Create the COMPLUS_DisableRetStructPinning environment variable, and set the value of the variable to 1.
  • Create a DWORDvalue of the DisableRetStructPinning entry at the following registry subkey, and set the DWORD value to 1:

    HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework

Then, restart the computer.

For Exchange Server 2013 that is installed in Windows Server 2012 R2

Create a DWORDvalue of the DisableRetStructPinning entry at the following registry subkey, and set the DWORD value to1:

HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework

Then, restart the computer.

For Exchange Server 2013 that is installed in Windows Server 2008 R2 or Windows Server 2008

Apply hotfix 2803754 that needs a restart, and then use one of the following methods to enable the hotfix:

  • Create the COMPLUS_DisableRetStructPinning environment variable, and set the value of the variable to 1.
  • Create a DWORDvalue of the DisableRetStructPinning entry at the following registry subkey, and set the DWORD value to 1:

    HKEY_LOCAL_MACHINE\Software\Microsoft\.NETFramework

Important Hotfixes when running Exchange 2013 on Server 2008 R2 and Server 2012

Additional pre-reqs needed above and beyond Exchange requirements
.NET Framework 4.5.1 deployed on all Exchange servers with CAS role
If .NET Framework 4.5.1 cannot be installed, a hotfix for .NET Framework 4.5 is required

Windows 8.1 Update (KB 2919355) prevents interaction with WSUS 3.2 over SSL

There is a known issue which causes some PCs updated with the Windows 8.1 Update (KB 2919355) to stop scanning against Windows Server Update Services 3.0 Service Pack 2 (WSUS 3.0 SP2 or WSUS 3.2) servers which are configured to use SSL and have not enabled TLS 1.2.

Issue Description

The problem is specific to the following scenario when all of the following are true

  1. Client PC has installed Windows 8.1 Update KB 2919355
  2. Windows 8.1 with Windows 8.1 Update KB 2919355 attempts to scan against WSUS 3.2 running on any affected platform:
    • Windows Server 2003 SP2, or
    • Windows Server 2003 R2 SP2, or
    • Windows Server 2008 SP2, or
    • Windows Server 2008 R2 SP1
  3. HTTPS and Secure Sockets Layer (SSL) are enabled on the WSUS server
  4. TLS 1.2 is not enabled on the server

Only users who have enabled HTTPS and have not enabled TLS 1.2 on their WSUS 3.2 servers and who are also using these WSUS 3.2 servers to manage PCs running the Windows 8.1 Update KB 2919355 are affected by this issue. Please note, while we do recommend the use of HTTPS on WSUS servers, HTTPS and TLS 1.2 are not enabled by default.

Workarounds

If you are using WSUS 3.2 on Windows Server 2008 R2, you may perform either of the following steps to restore the scan functionality if you have deployed the Windows 8.1 Update KB2919355.

  • Enable TLS 1.2 (follow the instructions under More Information > SCHANNEL\Protocols subkey), or
  • Disable HTTPS on WSUS

If you are using WSUS 3.2 on an operating system other than Windows Server 2008 R2, you may perform the following step to restore the scan functionality.

  • Disable HTTPS on WSUS

When Microsoft releases an update that resolves the issue, you may re-enable HTTPS on WSUS.

Microsoft plans to issue an update as soon as possible that will correct the issue and restore the proper behavior for Windows 8.1 Update KB 2919355 scanning against all supported WSUS configurations. Until that time, we are delaying the distribution of the Windows 8.1 Update KB 2919355 to WSUS servers.

You may still obtain the Windows 8.1 Update (KB 2919355) from the Windows Update Catalog or MSDN. However, we recommend that you suspend deployment of this update in your organization until we release the update that resolves this issue. You may also find the workarounds discussed in this article to be useful for testing this Windows 8.1 Update for your organization. Thank you for your patience during this time.

Incompatibility between Windows 8 roaming user profiles and roaming profiles in other versions of Windows

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.

Microsoft release a cool tool named Disk cleanup on Windows 7 Sp1

Microsoft released an update yesterday for the Disk cleanup utility. The problem Windows keeps copies of installed updates from Windows Update, even after installing newer version of updates. So the older versions of updates that are no longer needed and taking up space.

In Windows XP era the uninstalls were just hidden folders under Windows directory so easy to clean. Since Windows Vista this is now stored in the Windows Services folder WinSXS.

The space used by WinSXS can grow significant. In the past you could remove Service Pack uninstall files which helped, but Service Packs are not so common anymore. I think Windows 7 will never see SP2, yet the updates keep filling the WinSXS folder every month.

After the update is installed (no reboot needed) and you run Diskcleanup:

cleanup1

and when you click “Clean up system files”

You’ll see new options:

cleanup2

This update of diskcleanup delivers a new option Windows Update cleanup which deletes older versions of updates that are no longer needed and just taking up space.

The update is available through Windows Update as important or direct download at KB article posted below:

KB2852386: Update is available that enables you to delete outdated Windows updates by using a new option in the Disk Cleanup wizard in Windows 7 SP1

Now unfortunately this update is not available for Windows Server 2008 R2, while there are plenty scenarios where cleaning up WinSXS folder is helpful there too!
