UPDATED : Windows 10 RTM & TH2 & RS1 (14393) & Creator Update (15063) & 1709 & 1803 & 1809 & 1903 – Enabling Deduplication

Hi everyone,

We finally have a working deduplication package for Windows 10 using Windows Server 2016 TP3 files.

Here’s the original thread where we’ve been talking about this : http://forums.mydigitallife.info/threads/57189-Working-Deduplication-files-for-Microsoft-Windows-10-Now-Updated-with-9926-files

This package is now fully functional and you can install it under Windows 10 Enterprise and Pro (haven’t tested for Windows Home).

Here’s how to proceed :

1) Download the package here : http://ul.to/pq9m8iqs

2) Run Install.cmd in an elevated command prompt windows

3) Change PowerShell Execution policy to Bypass : Set-ExecutionPolicy -ExecutionPolicy Bypass

4) Import deduplication Module : Import-Module Deduplication

5) Enable deduplication on volume : Enable-DedupVolume -Volume X:

6) Start deduplication job on volume : Start-DedupJob -Type Optimization -Volume X:

I’ll make a video but it’s pretty straightforward.

Have a nice evening.

Here’s the result on a 1 To SSD :

Before Deduplication

This is before deduplication job as optimized the drive

After Deduplication

This is after deduplication job as optimized the drive

Get-DedupVolume

Result of deduplication

Have fun

EDIT 22/08/2015 : For MacBook Pro’s users like me, you need to disable a service installed by BootCamp tools.

You can find this information in this post : http://www.edandersen.com/2015/07/06/windows-10-on-mac-bootcamp-fixes/

It prevents us from using VSS services correctly.

The results are even more spectacular :

After 4 days of background deduplication

After 4 days of background deduplication

After 4 days of background deduplication - PowerShell

After 4 days of background deduplication – PowerShell

EDIT : I reuploaded package to Uploaded.net and changed the link.

You can also download this package at MEGA here : https://mega.nz/#!H4BxyJyb!15q0FzR8RX1Km5g1trc0qOkSHAypoU9x8fMW_G-8VXw

EDIT 30/08/2015 : Just a reminder : The default configuration is to deduplicate files older than 3 days. This is why, when you start a deduplication job on a new hard drive, you don’t see any changes.

You can change this behavior by setting the minimum file age to 0 or 1. The command is : Set-DedupVolume -Volume W: -MinimumFileAgeDays 1

EDIT 11/09/2015 : Thanks to Paul Munro, here’s the correct way to proceed when you’re not part of the Insider Program.

First, my complete registry key regarding the Insider Program adhesion is the following

Now, my computer is booting from vhdx (an old habit I took when I was playing with Windows 7 and Windows 2008 on my computer). I’m using both Hyper-V and VMWare Workstation on my computer but I need (as stated in a previous post) to disable hypervisor to be able to use VMWare Workstation.

Believe me or not, when I start with hypervisor off, Windows 10 tells me I’m not part of the Insider Program… This is the same computer, the same OS but the only option that changed in the bcdboot loader is Hypervisorlaunchtype Off….

Well, now, thanks to Paul, I added the Testsigning On option and it now works.

In this precise case, when you have multiple bcdedit entries, you need to type the following line :

bcdedt /set {165c7xxxxxxx} testsigning on (in my case : bcdedit /set {165c7ad6-4564-11e3-80ee-94fe320f6959} testsigning on)

Here’s what my bcdedit looks like :

Bcdedit

Here’s my bcdedit

UPDATE 20/11/2015 :

A working package made by moderate on MyDigitalLife is now available with dedup files from Windows Server 2016 TP4 build 10586.

This package installs correctly on Windows 10 TH2 build and doesn’t have any problem with the certificate.

Here’s the link to this package  :

Uploaded : Deduplication_W10TH2_b10586_x64_Replaced.rar

Mega : Deduplication_W10TH2_b10586_x64_Replaced.rar

I’ll also add that the problem encountered on MacBook Pro is solved using Bootcamp 6.0

Have fun

UPDATE 02/08/2016 :

As Windows Server 2016 build is now aligned with the latest Windows 10 build (14393) aka 1607, we finally have a working deduplication package.

Mega : Dedup_10.0.14393.0.zip

Uploaded : Dedup_10.0.14393.0.zip

Thanks again for abbodi1406‘s work on this part.

    I followed the instructions and apparently got deduplication package “installed” without errors in a Windows 10 virtual machine running under virtualbox in Win 8.1 host. I checked the running services and confirmed that the data deduplication services were running. I enabled deduplication on a VHD volume and started an optimization dedup job. It seemed that the optimization process did not actually run. I could the see job queued in the first few seconds with “get-dedupjob” but would see no job information after a few seconds. I have tried to uninstall and re-install serveral times and experienced the same thing. I attached a deduped USB drive (deduped in Win 8.1) and the Win10 VM could not read the files in the deduped volume. The same drive attached to the Win 8.1 system could be read without problem. What could I have done wrong?

      Hi,
      I would start by :
      1) Check your System Eventlog and tell me if you have any error related to deduplication.
      2) Check using msinfo32 if you have the dedup.sys driver loaded and running in the System Drivers section.
      The dedup.sys driver is the only driver needed to read your USB deduped stick.

      I tried this in a VM (even with Windows Server 2016 T3) to dedup a drive and I didn’t have any result at first. Then I let the background task dedup the drive and it was working.
      Thanks

        I saw one error about failed starting of dedup service due to license explicitly revoked by issuer. Since the dedup service was actually running, that error might be related to my uninstallation of the dedup package. One error mentioned stopping of dedup service due to “ran out of memory”.

        The Dedup.sys driver was loaded but was not running. How to make it run? What might have caused it to stop?

        Thanks.

        • cgirardy
          25/08/2015 at 16:40

          Can you try in a new VM ?
          The driver should load without you doing anything as it’s a system driver.

          EDIT : Here’s something you can try :
          Add this code to your registry :
          Windows Registry Editor Version 5.00

          [HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\WindowsSelfHost\Applicability]
          “EnablePreviewBuilds”=dword:00000001

          It seems that you’re not signed in the insider canal, there’s a certificate problem that prevents dedup.sys driver from loading.
          Can you test and let me know please ?
          Thanks

          EDIT 04/09/15 : the key has to have the value = 1

          • 11/09/2015 at 11:20

            The reg edit above didn’t work for me, in the event log i see

            The Dedup service failed to start due to the following error:
            A certificate was explicitly revoked by its issuer.

            I’ve set the machine to test signing using

            Bcdedit.exe -set TESTSIGNING ON

            done a reboot and the service is now started. I’m running release 10240 Enterprise.

            Looks like it was the codeintegrity service that was blocking its launch.

            Hi Paul,
            Thanks a lot for this.
            When we started to work on this package, this option wasn’t working.
            I presume that, changing the way we install the package helped this option to work as it should.
            I’ll update my post with your information.

    Only one thing is preventing me from upgrading Windows 8.1 to Windows 10 and it’s the deduplication. I have many virtual machines stored to my SSD disks and there’s no way to store them without dedup. Hope Microsoft brings dedup to Windows 10 client OS so we don’t need to use hacks like these because there’s always a chance that something goes wrong when installing updates etc in future.

    Vote!

    Hm i tried this package with the “Outer” Install.cmd (as admin) and the TrustedInstaller starts the “Inner” Install.cmd its terminating realy quick (for my feeling and the amount of commands) and there are no Dedup Services and no Dedup Files in the Windows Directory….
    But i cannot say whats exactly going wrong here, the CMD Windows of the TrustedInstaller Process terminates realy quick…

      OK, you wrote it in your first post, sorry about that.
      Can you try taking a picture of the install (just post the link on TinyPic for example) because I really don’t see what’s going on on your computer.
      The install procedure is pretty straightforward and no one had problem installing the package.

    Should I be member of insiders before I can use this? I downloaded that package from mega and I was able to install deduplication and import deduplication module to PowerShell and configure it. But it does nothing to my files. When I open EventViewer I can see that it’s giving erros about a driver that is not loaded.

    • cgirardy
      03/10/2015 at 14:03

      You need to be part of Insider program for this driver to start correctly.
      You can also add the driversigning option in your bcdedit but I cannot be 100% sure it’s working for everyone.

    04/10/2015 at 10:26

    Do you know can I be part of Insiders without really installing any preview builds? I would like to upgrade to Windows 10 but I really don’t want to loose 8.1 dedup functionality.

    • cgirardy
      04/10/2015 at 11:16

      Hi,
      To answer your question : I have installed build 10240 without installing any preview build.
      I boot from vhdx and I didn’t upgrade my Windows 8.1 as the upgrade in a vhdx is not supported by MS.

      BTW, this morning, I’ve tried version 10558 of Windows 10 Pro in a vhdx.
      I installed dedup driver and it worked without being part of Insider program.
      I’m gonna post some screen captures so you can see with your own eyes…
      That let me think that the problem comes from the fact that the dedup files extracted from server build 10514 are newer than Windows 10 build 10240.

  13. 05/10/2015 at 04:48

    You can try ZIPmagic on Windows 10 after enabling data deduplication. It has a nice GUI wrapper around all data deduplication commandlets, maximizes compression savings, and even has its own data compression driver which projects increased total disk capacity and free space in line with your actual disk compression ratio. The compression ratio that is projected is initially based on your actual compression ratio, while remaining fully user customizable. Try it out – works like a charm!

    It is not compatible with Windows 10 Threshold 2

    • cgirardy
      15/11/2015 at 19:52

      On the contrary, it’s more compatible with TH2 then it was with 10240 because it doesn’t have the certificate problem :

    I am having some problems running Start-DedupJob on Windows 10. I got the feature installed sucessfully, but i am having some problems running DeDupJobs.

    Data Deduplication failed to start job type “Optimization” on volume “X” with error “0x80565309”. A required filter driver is either no installed, not loaded or not ready for service.

    I cannot find anything regarding this error online, neither on the errorcode itself or on the whole error message.

    I do not know if i am missing the driver, or if i have it loaded.
    Had the same error on both 10240 and 10586.36 Build.

        I finally fixed it with for my 10586-build. But cannot get my 10240-build machine running with dedup.

        Pretty sure i took the latest package for 10240.
        i can see dedup.sys loaded in Systeminfo. (It is stopped and not running?)
        I can run all the commands but when i do Start-DedupJob it calls the “missing filter driver”

          16/02/2016 at 09:10

          Happy to hear that you solved the problem on 10586.
          The dedup.sys must be running.
          You can apply dedup package from build 10586 on build 10240.
          It works even better as you don’t have the certificate problem.

    Thanks a lot! I just tried the Dedup_10.0.14393.0.zip with my Win10 1607 and it’s a lot easier than it seems 🙂
    Just forget the instructions from above, extract zip and run (with powershell) the 2 lines from the included install.txt and you are ready to:
    Enable-DedupVolume -Volume X:
    Start-DedupJob -Type Optimization -Volume X:
    Get-DedupJob
    Get-DedupVolume

    A question: what happens if I plug this HDD into a computer which doesn’t have dedup?

    • cgirardy
      16/10/2016 at 20:01

      Hi,
      Happy that you managed to install this.
      When you plug your HDD on a computer that doesn’t have dedup capability, you’ll see your files but you won’t be able to open them.
      You’ll be able to use this HDD on Windows Server 2012 / 2012 R2 / 2016 and Windows 10 with dedup package installed.
      This component is magical but it has to be used with caution.

        Thanks. When I view the properties of a file, the “Size on disk” is 0 Bytes, and for multiple files or folders it is quite small. Is this the same on server versions where this is supported officially? Or do I need to update some dll? It would be quite interesting to get more info about what dedup did for a specific file.

        • Alex
          18/10/2016 at 13:55

          Ah, sorry, should have googled before. I found some info here: http://www.urtech.ca/2013/08/solved-why-does-data-deduplication-have-size-on-disk-and-deduplication-numbers-not-match/

            We only have cmdlets as this is not a built-in option.
            Here’s what it looks like on a server :
            Deduplication on Windows Server 2016

          • 24/10/2016 at 21:31

            This is what I get on that URL:

            Not Found

            The requested URL /dedup/datadedup.zip was not found on this server.

            However, you can try ZIPmagic or DiskZIP if you are looking for a mature dedup GUI.

            It doesn’t seem to be pointing to a file.
            Are you sure of your link ?

    When I start the DedupJob, I can see it’s queued, and then initializing (as per the “Get-DedupJob” command) but eventually it fails after initialization. As per msinfo32, the driver is installed and running but the system eventlog shows two errors:

    “A timeout was reached (30000 milliseconds) while waiting for the Data Deduplication Volume Shadow Copy Service service to connect.”

    “The Data Deduplication Volume Shadow Copy Service service failed to start due to the following error:
    The service did not respond to the start or control request in a timely fashion.”

    I checked my services and I see the Data Deduplication Volume Shadow Copy service which is set to automatic (but not running) and I can’t manually start it and gives me this error when I try:

    “Error 1053: The service did not respond to the start or control request in a timely fasion.”

    Any Ideas?

      Hi,
      Basic questions :
      – On which version of Windows 10 did you install the dedup package ?
      – Which dedup package did you use ?
      Thanks

      • 06/02/2017 at 03:39

        Windows 10 Pro, Build 14393.693, used the “Dedup_10.0.14393.0.zip” installer from this post.

        • cgirardy
          06/02/2017 at 18:55

          Can you try with this new manual package and let me know please ?

          Dedup Package Manual installation

          • 06/02/2017 at 19:23

            Downloaded your new package, it said it was already installed so I uninstalled first then ran the install cmd again. Still same System Log errors about shadow copy service and no results.

            06/02/2017 at 19:56

            I’m a bit puzzled here.
            Is it a x64 build of Windows 10 ?

          • 07/02/2017 at 18:09

            Yes it’s a x64 build. Could it have anything to do with the fact that the drive I’m trying to dedup is a storage spaces thin provisioned drive?

          • cgirardy
            08/02/2017 at 22:37

            Honestly, I haven’t tried in this configuration so I cannot confirm but I’ll try and let you know what it gives.
            I’m leaving on holidays starting tomorrow until Feb 27 so I might not be able to answer quickly but I’ll have a few spare time between my scuba dives so I’ll give it a try 🙂

    Hi, after the update to 1503 aka 1703 my dedup drives are no more working. Do you have any updated package to support this version?

    • cgirardy
      20/04/2017 at 21:27

      Hi,
      There’s a new package for 1703. I’m updating the post right now.

  24. 25/07/2017 at 16:23

    I am having issue with 15063 package and 15063 enterprise. When I use the DISM package DISM returns that the files are not supported by the OS, When i use the manual package it installs correctly I can import the module enable and set the file age on a volume but when I run the job it only sit at initializing. I have the driver installed there are no errors in the event log the only thing I am seeing is vss timing out. Do you have any suggestions ?

      26/07/2017 at 08:51

      Hi,
      I’m currently working on 15063.483 without any problem.
      What type of error do you have exactly ?
      Thanks

        I have a similar problem. After Windows update the data wasn’t accessible anymore. After installing the new package

        I got access to the data again, but it seems that Optimization, GarbageCollection and Scrubbing aren’t doing anything. Get-DedupJob just shows Initializing for some time then it terminates without any error.

      • Emil N.
        11/08/2017 at 11:57

        The problem described before appears with manual installation package.

        I used manual because the DISM package didn’t install. The error was 0x800f081e with message that the packages are not valid for the image. winver shows “1703 (Build 15063.540).

        In the mean time I now have to install the manual package again to get access to the data.

        It would be create to get a solution, because in will run out of disk space.

        Thanx!

          I am experiencing the same problem
          Windows 10 enterprise 15063.540, tried both the packages (dism and manual)
          It just sits at initializing and then it is gone

    Any updated dism package for the latest build (10.0.16299.15)? A guide on how to create the cabfiles from an installed server 1709 will do too …

    • cgirardy
      07/11/2017 at 18:41

      Hi,
      I’ll post an updated DSIM package for 16299 as soon as it’s fully tested.
      At the moment, there’s a problem with the package I have when Hyper-V is enabled : it somehow breaks PowerShell dedup commands and we still haven’t found a solution.
      If you plan not to use Hyper-V on your Windows 10 computer, here’s a link to the package :
      Dedup_16299_DSIM.zip
      This pacakge is on Mega

        I installed Dedup_16299_DSIM.zip on a Windows 10 Pro “server” with Hyper-V running. I didn’t encounter any problem of using Powershell dedup comdlets. The common commands like get-dedupstatus, start-dedupjob, set-dedupvolume etc. all worked as expected.

      • Carlos Sosa

        Hi,

        I installed it on 16299.19 Education. I didn’t have any issue and everything seems to be working.

        BTW… Do you happened yo know if there is some way to use it on SD cards? Maybe tricking Windows to believe it’s a fixed drive?

        Thanks for all your works. Cheers.

          Hi everyone, I have found the culprit package : RSAT tools.
          The ones found here : https://www.microsoft.com/en-us/download/details.aspx?id=45520 (WS2016 and 1709 in x64 version) cause this problem.
          When I remove the package, I gain access to the PS dedup commands.

          EDIT :
          It obviously doesn’t have to do anything with the RSAT tools… If I wait for around 15 minutes after startup, I loose the PS dedup commands…
          Is it a soft I’m starting manually that does this or a service that has a delayed start (for example SCCM Agent) ?
          I’ll dig into this and let you know.
          As I’m the only one having this problem, I’ll update my post and add the file to my uploaded account.
          I must add that this problem doesn’t prevent me from accessing my deduped files… it only concerns the PS commands.

    Thanks for the quick reply! Unfortunately I am using Hyper-V and use data deduplication to save space on my SSD. Despite the warning however I installed the package and so far have been able to successfully run all the dedupjob commands and have saved a significant amount of GB. Can you tell me where you encountered the errors?

    • cgirardy
      12/11/2017 at 16:17

      In fact, I obviously have a problem on my computer… I have to investigate this as in a simple VM + Hyper-V function, everything works.
      Here’s the error I get on my computer :
      PS C:\Windows\system32> Get-DedupStatus
      Get-DedupStatus : MSFT_DedupVolumeStatus – HRESULT 0x800706ba, The RPC server is unavailable.
      At line:1 char:1
      + Get-DedupStatus
      + ~~~~~~~~~~~~~~~
      + CategoryInfo : NotSpecified: (MSFT_DedupVolumeStatus:ROOT/Microsoft/…dupVolumeStatus) [Get-DedupStatus], CimException
      + FullyQualifiedErrorId : HRESULT 0x800706ba,Get-DedupStatus

      PS C:\Windows\system32>

      It might come from an application I’m installing on my computer. I have this error on 2 computers in fact. One that upgraded from 1703 to 1709 and mine that has been installed from scratch. They both have the same software so I’ll check into this.

    I’m late to the game.
    My Win10 is a Hyper-V VM and the Dedup_15063_Manual.7z installed fine and the services run fine. The drive I want to dedupe, E: drive is a Hyper-V drive (.vhdx). I tell it to dedup that volume, it says it is queued and it never dedups.
    The get-dedupstatus always returns “SavedSpace 0 B”

      Hi,
      Did you set the MinimumFileAgeDays option ?
      – Set-DedupVolume -Volume W: -MinimumFileAgeDays 1

      Thanks

    As you know, 1903 is currently out.

    Any thoughts on dedup support for 1903?

    This has become our bi-annual traditional dance!

      Sorry everyone,
      I haven’t been on my site for quite a while now.
      I’ve updated with 1903 package.
      The 1809 package is also working on LTSB versions. What’s your problem with the 1809 package ?
