Upgrading Windows Release Candidate/Preview to RTM

I am in general against upgrading to newer version, even from Windows 7 to 8 I would prefair a clean install. But it's nice to have the possibility to upgrade.

One of my Laptop was running everything I need for a presentation with demos that I shall host in 2 day's time. And it's running the Release Candidate version of Windows Server 2012. The RTM version of Server 2012 are available today, and I would of course like to show that I am a modern guy running the latest bits :-)

Remembering back to Windows 7 / 2008 R2 beta/RTM days, there was a way of upgrading between the different beta and rc Versions. I tested this out from Developer preview to newer version but it did'nt work.

BUT! trying it today it from RC to RTM it did work :-)

Will I save disk space with Windows Server 2012 Deduplication?

First thing first, Windows Server 8 beta will change name to Windows Server 2012. This was officially announced at MMS2012 and the release date will be later this year.In juni we will se the next test version, called "release candidate"

One of many new cool features are the disk deduplication, check out my blog post here for more info.

There is a tool to check out how much space you might save by using deduplication, but for now the tool are only available after you have enabled the file server feature on a Windows Server 2012 installation. And that's to bad since you might want to test out how much space you can save with an Windows Server 2012 upgrade.

But luckily there is a way to cheat....
