This week's newsletter is about features that are being deprecated in Windows Server 2012. Change is always difficult, so it's a good idea to begin preparing for the future by familiarizing yourself with the features that won't be included in future versions of Windows.
But before we examine this subject, let's take a look at our Mailbag...
Arnaud from Pittsburg, USA, had some helpful feedback concerning the Windows Performance Toolkit which we covered in our Profiling Performance issue:
I just read through the latest WServer Newsletter and wanted to share a recommendation. You recommend using xperf from the Windows Performance Toolkit to capture detailed system events, but I would point your readers to the new Windows Performance Recorder and Windows Performance Analyzer instead. It's the latest iteration of the same tools for Windows 8 (but backwards compatible) with a simplified and streamlined interface. Instead of needing to pass xperf a line of parameters WPR lets you start capturing with the click of a button and WPA allows you to do your analysis in a much nicer and flexible environment.
The tools come bundled in the SDK for Windows 8:
There's a good overview here:
And a detailed demonstration from the 2011 Build conference:
The devs on the Performance team did a great job simplifying the process for those of us that don't use these tools every day, and I think your readers will find that starting with them instead of xperf leads to a much shorter learning curve.
Thanks very much for pointing us to that info!
Also in that issue was a tip about copying large files using Windows Explorer. A couple of readers wrote to offer suggestions concerning an alternative tool for copying files:
Valerie from Oregon, USA - I have long had problems when trying to copy a lot of files with Explorer but then I found the free utility TERACOPY:
It seems to be faster, can include a verification pass so is more secure, and seems to have a lot less trouble than explorer. Best it integrates right in so that when I use explorer to copy files, it automatically invokes Teracopy without my having to do anything different. Definitely on my recommended list along with "Everything" (a file search utility) and a few other gems I've found over the years.
And from a reader named Rich - I've been loading and using teracopy on all my machines for several years now. Much more capable than Explorer's native copy, give it a try next time you run into strangeness when copying large numbers of files and/or large files. Windows 7's copy has some of the features it brought to XP, like skip copying files already at destination, but teracopy has several more options, like skipping older files, and/or renaming the files to be copied automagically.
As you may remember, our Snapshot Snags issue included a request for assistance from a reader named Alain in South Africa which we threw out to our readers for their suggestions. Alain has expressed his thanks to WServerNews readers as follows:
I had a good read through the responses you had to my query. I want to thank you very much for putting this into your newsletter. I will be testing out the options that were presented, and will let you have feedback when I have found the solution.
No problem Alain, I'm sure we're all happy to help. IT work can be frustrating at times, and being connected with the larger IT pro community can help relieve a lot of that frustration. BTW here are a couple more responses which we received since our last issue:
Ken, a Network Performance Analyst and Project Engineer in North Carolina - MRTG will do what he wants if the port has an SNMP agent:
Martin, an IT Manager from Germany - You might give the free version of PRTG a closer look. Running on the server itself it doesn't generate any additional traffic, otherwise it's just a SNMP request and reply every 5 minutes:
Now on to this issue's main topic.
Software features come and go, things change, life moves on. A few shops were surprised when they tried joining their brand new Windows 7 PCs to their still-kicking Windows NT 4.0 domains. Can't be done:
In fact, a lot of features got deprecated with the release of Windows 7 and Windows Server 2008 R2:
So what's being deprecated with the upcoming release of Windows 8 and Windows Server 2012? Before we examine that question, we should pause and consider because just as "anything is negotiable" and "anything is for sale at the right price" it may also be that ANYTHING IS COMPUTABLE IF YOU HAVE ENOUGH CANDY:
Features removed or deprecated in Windows Server 2012
Let's start with a condensed list of some features, tools and functionality that have been removed in Windows Server 2012:
- XDDM drivers
- TCP Offload (but just VM Chimney, not Native TCP Chimney)
- Static VMQ
- Support for 32-bit cluster resource DLLs
- Support for SAL Server 6.5 or earlier
Now here's a quick list of features that are now deprecated in Windows Server 2012, which means you can expect to see them removed in the next version of Windows Server:
- SNMP service
- SMTP service
- LPR/LPD printing
- Subsystem for UNIX-based Applications (SUA)
- Transport Driver Interface (TDI)
- Support for 16 and 32 bit ODCB
- Support for NDIS 5.0 , 5.1 and 5.2 drivers
- Windows System Resource Manager (WSRM)
- Windows Management Instrumentation Command-line (WMIC)
- The root\virtualization WMI namespace (you must now use root\virtualization\v2)
That last item may how Hyper-V admins will manage their environments. For example, one impact of the change is that you won't be able to use the Windows Server 2012 version of Hyper-V Manager to manage downlevel Hyper-V hosts. That means you'll need to use two sets of management tools to manage a mixed 2012/2008/2008 R2 Hyper-V environment. For some insight into the reasons behind this change, see the link to Ben Armstrong's post in the Tech Briefing section of this newsletter.
The "official" list of removed/deprecated features is here:

More removed or deprecated functionality
It would be nice if the "Features Removed or Deprecated in Windows Server 2012" TechNet page were the full list of features being removed or deprecated in Windows Server 2012. Unfortunately, if you go digging around some more you're likely to find more removed or deprecated features. For example, the above page fails to mention that you can no longer use the High Availability wizard to deploy the Print Server role on a failover cluster, and in addition the Add-ClusterPrintServerRole cmdlet no longer works. See the bottom of this page for details:
And those of you who are used to using Dcpromo.exe to install Active Directory will need to know that Dcpromo.exe has been deprecated as well in Windows Server 2012, as the Note on the following page indicates:
I expect that updating the "Features Removed or Deprecated in Windows Server 2012" will be an ongoing process for Microsoft over the next several months, and in the meantime you might try digging around for more info by using this Bing search query:
There's probably more
Be aware also that the above TechNet pages may not tell us everything that has been deprecated or removed in Windows Server 2012 as there may be some additional under-the-hood changes in the platform that may cause compatibility issues in certain scenarios. For example, the following post from the RDS team indicates that the capability of having a dedicated RD Session Host server running in Redirection mode has been removed from Windows Server 2012 and the functionality has been merged into the RD Connection Broker role:
I'm not sure what impact this may have, but shops that have RDS deployed will want to know this.
Windows PowerShell 3.0 is probably another example here since it introduces a ton of new features and capabilities:
While I'm sure Microsoft has tried very hard to make sure these new features don't break any functionality in existing scripts written for PowerShell 2.0, my guess is that a few v2 scripts will throw exceptions when you try to run them on a v3 system (just like a few v1 scripts did when they were run on v2). But perhaps this is for good reason, as a few of the under-the-hood changes in v3 are likely to have been fixes for lingering bugs in v2. Unfortunately when you fix a bug, the workaround for that bug sometimes no longer works.
It's a bit like driving a car. You've been driving for years, and you're used to your old clunker and can handle it well. Then you decide to buy the new model, and they've changed where some of the controls are, and when you try to turn up the air conditioning the volume on the radio goes up instead. You're frustrated at first, but after a while you begin to see the logic of some of the changes and in the end you find they make your driving experience better. Except for the few annoyances that appear to be regressions, but you learn to work around those.
There have also been some significant changes to how WMI is implemented in the new platform. In my opinion these changes are for the better as they look towards the future of distributed systems management, but some of them might have an impact on certain management tools and scripts you may be using. See the link to Jeffrey Snover's blog post the Tech Briefing section of this newsletter for more info.
Features removed or deprecated in Windows 8
Unfortunately there doesn't seem to be an official page yet concerning features that have been deprecated or removed in Windows 8. Of course, maybe that's because Windows 8 is so different that such a page would be too long. Guy Thomas, a Microsoft MPV in the UK who manages a terrific site called Computer Performance, has tried to put together a quick overview:
If any of our readers have found additional info about removed/deprecated features in Windows 8, feel free to email me at [email protected]
Tip of the Week
You've downloaded a PowerShell script from a reliable website and you want to use it to perform some task in your test environment. The script isn't signed, so you use the Set-ExecutionPolicy cmdlet to set your PowerShell execution policy to Unrestricted. But when you try to run the script, you get an error saying the script can't run.
Try this: right-click on the .ps1 file for the script in Windows Explorer, select Properties, and click Unblock if there is an Unblock button on the General tab of the Properties page for the file. We often forget that the default behavior since Windows XP SP2 is to restrict what you can do with files downloaded to your computer. See this KB article for more info:
What if you downloaded a bunch of files into a folder and want to unblock all of them? You can use the Windows Sysinternals utility called Streams to do this as described in this thread from the TechNet Forums:
It gets even better on Windows 8 with the new Unblock-File cmdlet of PowerShell 3.0:
