Hello,

I'm missing the emdgmt file for ReadyBoost. I've been searching but can't find anything.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt

(P.S.: I've already used software to try to get it back, but nothing works.)

    Hello,

    Which Windows?

    To see if it exists, do this if it's Windows 10

    => In Cortana / search, type CMD
    => Click on run as administrator
    => In the prompt, copy/paste reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt" and confirm
    => What does it say?

      I am on Windows 10 and it tells me this

      Error: Error: the system could not find the specified registry key or value.

    Do the same thing with this:

    reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion" >> %userprofile%/desktop/key.txt

    A key.txt file will be created on the desktop, post it here and give the link obtained:

    reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion" >> c:/key.txt

    The file will be created at the base of C:

    (Ps: I've been struggling for months and you can't send your emd file)


    It's not a file, it's a registry key, and it's surprising that it's not present.

    Do you have a USB drive connected to the PC? If not, plug it in, check in Explorer that it's present, and then redo what's in this message: https://forums.commentcamarche.net/forum/affich-36931892-il-me-manque-un-fichier-reg#1

      I have my USB key (SD card) plugged in since the beginning, it works with ReadyBoost and is urgent, but it tells me this

      https://up.security-x.fr/file.php?h=R5e628088a5a6763a04e1a0bcd626ca9b



      I did my research and everything is linked to this key

      my USB key is in NTFS.

      Hi,
      ReadyBoost has been around since Vista for optimizations that I think are well integrated into Windows 10. This registry is no longer relevant, is it?

        If that register is ReadyBoost, it won't work in my case, I think.

    Is the key visible in the explorer?

    We will try to create the registry key:

    Remove the USB key, then do as before with this

    reg add "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt"

    Restart the PC, reconnect it and see what it gives.

    The key has appeared, thank you very much, but how do I make it so that ReadyBoost doesn't show me the following message:

    https://up.security-x.fr/file.php?h=R5e628088a5a6763a04e1a0bcd626ca9b

    Because it took several months for me to find a general solution online, and with you, it only took 1 hour.

    OK,

    To check if the registry key has been implemented:

    reg query "HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt"

    It's good, give me this

    HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\EMDMgmt
    (default) REG_SZ

    What is the configuration of this PC? Is there an SSD on it?

    Take a screenshot of:
    => Windows + R
    => Type msinfo32 and confirm

    Was the ReadyBoost tab visible before the creation of the registry key (in your first message)?

    Le disque dur est un SSD. Il apparaît en bas, je ne savais pas à quoi ça servait et c'est après des recherches que j'ai su qu'il me manquait la clé emdmgmt.

    I think it’s the SSD that’s causing the problem. If you had a hard drive, especially with the processor you have (Celeron) which is not very fast, it would work, because it’s a matter of read/write and the SSD is already much faster than a hard drive.

    On my PC, with a Core i7 and a hard drive, it works; if I had an SSD, I think I wouldn’t have access.

    In this tutorial, it’s clearly stated: https://www.malekal.com/comment-accelerer-windows-avec-readyboost/#Comment_activer_ReadyBoost_sur_une_cle_USB 

    To use ReadyBoost, you need an older computer or one that does not have recent specifications.


    Unfortunately, I think there’s nothing more to do.

    OK,

    If you ever find a solution to activate it despite the SSD, don't hesitate to post the solution here, it will surely help others.
