Enable Deduplication on your Windows 8.1

This is just an update to my past post on how to enable data deduplication on Windows 8 (which normally is only available on Windows Server 2012). It took me awhile but I’ve not had time to look into this. The good news is it’s here thanks to a blogger Mailspintoys for the files. I’ve made copies of those files and shared it on my skydrive too but you could very much also download it from his blog.

One reminder though, this didn’t work for me when I was testing it on a VM and it only works if you installed Windows 8.1 physically, at least from what I’ve tried. That means you have to take the dive into Windows 8.1 without trying it around on a VM. Credit goes to Corne van Bochove for the valuable sharing in my past post and Mailspintoys for the extracted files.

The new command line to execute is as below:-

dism /online /add-package /packagepath:Microsoft-Windows-VdsInterop-Package~31bf3856ad364e35~amd64~~6.3.9600.16384.cab /packagepath:Microsoft-Windows-VdsInterop-Package~31bf3856ad364e35~amd64~en-US~6.3.9600.16384.cab  /packagepath:Microsoft-Windows-FileServer-Package~31bf3856ad364e35~amd64~~6.3.9600.16384.cab /packagepath:Microsoft-Windows-FileServer-Package~31bf3856ad364e35~amd64~en-US~6.3.9600.16384.cab  /packagepath:Microsoft-Windows-Dedup-Package~31bf3856ad364e35~amd64~~6.3.9600.16384.cab /packagepath:Microsoft-Windows-Dedup-Package~31bf3856ad364e35~amd64~en-US~6.3.9600.16384.cab

dism /online /enable-feature /featurename:Dedup-Core /all


Basically the only difference from the previous one is the version number changed from 6.2.9200 to 6.3.9600. Hope you enjoy the feature as much as I did. For a more complete post on it go to my previous blog on this. https://weikingteh.wordpress.com/2013/01/15/how-to-enable-data-deduplication-in-windows-8/

  5. Any idea why this is happening?

    Enable-DedupVolume : MSFT_DedupVolume.Volume=’C:’ – HRESULT 0x8056530b, The specified volume type is not supported.
    Deduplication is supported on fixed, write-enabled NTFS data volumes and CSV backed by NTFS data volumes.
    At line:1 char:1
    + Enable-DedupVolume C:

    + FullyQualifiedErrorId : HRESULT 0x8056530b,Enable-DedupVolume

    here’s a dump from diskpart:

    DISKPART> list volume

    Volume ### Ltr Label Fs Type Size Status Info

    thank you ! I’m using dedup to store iso and hyper-v vm’s on 8.1 /ssd and performances are excellent.

    Can you try to export the cabs from the Server 2012 R2 for storage tiering?
