10 thoughts on “What’s new in Windows 10 Version 2004 (20H1)”

  1. Isn’t this the update that also implements some changes to GPU drivers/WDDM/something of the sorts, that fixes performance issues when using multiple monitors? I don’t see it on the list, and that change is probably the only feature that I like in this update, except for limiting bandwidth for updates (that’s long overdue!)

  2. Mesmo na próxima atualização 20h1 continuará aquele quadro preto horrível em “iniciar”. Que pena.

  3. 2004 seems to have broken some things : I have been able to have title bars gray when inactive and of another colour when active… Now it uses the win10 colour (singular : Micorosft is of the opinion that one shouldn’t use title bars anymore, and if ther are tirle bars they should all have the same colour, active or not … and Office has its own coulour scheme ! :-(. The settings interfere with whatever one can do in registry.

    Coorection : it worked even for File Explorer, now it works for “normal” programs, but not for File explorer anymore.

    But thanks a lot for your work : it makes windows bearable (more or less, and it removes part of “your computer is yours, but what it does, and you do with it, is ours” syndrome.) I should turn to Linux, but they are copying the ergonomics of Windows and I have not yet found a distribution that lets one set the user interaction correctly (colours, navigation items (as scroll bars, …), …)

  4. Windows Version 2004 (Build 19041.329)
    Context menu for more than 15 files
    Key MultiInvokePromptMinimum

    welchen Wert ich auch einstelle, effektiv werden nur max. 16 Menüs vom Explorer verwendet, obwohl der Registrierungswert auf 62. eingestellt ist.
    Wird der Key in dieser Windowsversion nicht mehr unterstützt oder gibt es einen neuen/zusätzlichen Eintrag?
    Bitte um Unterstützung.

    whatever value I set, only max. 16 menus used by Explorer, although the registry value is set to 62nd.
    Is the key no longer supported in this Windows version or is there a new / additional entry?
    Please support.

  5. I still have one dell optiplex on 1903 and wont update to 2004
    it always backs out even though it says its available
    for upgrade . Any idea when MS will get this fixed?

  6. As an FYI, 2004 appears to have also broken Windows Live Mail. Headers on emails will download but not the body of the message.

    “Message could not be displayed
    Windows Live Mail encountered an unexpected problem while displaying this message. Check your computer for low memory or low disk space and try again.”
    FETCH completed.
    Account: Hotmail xxxxxxx
    Server: imap-mail.outlook.com
    User name: xxxxxxxxxx@hotmail.com
    Protocol: IMAP
    Port: 993
    Secure(SSL): 1
    Code: 800c013e
    Several reported fixes online but none have seemed to work for me. :(

  7. I’ve heard from a reliable source that this new version will regularly defragment your SSD. Supposedly if left on this will shorten the life of the drive as you should never defrag a SSD, only trim them. You can shut the defrag feature off in the drive’s tool’s tab , then optimize, then scheduled optimization & set that to off. That’s what I have set until I find out they fixed that issue.
