  1. Sry, didn’t read the whole article. Still laughing at “As you may already know, Windows 10 ’19H1′ development is over. Microsoft has started fixing its minor bugs.”

  2. Hopefully there’s also improvement for dark theme in file explorer.. thanks for this Sergey. Worth the upgrade for me.

  3. Thank you, this list of updates was very informative! It’s nice to see Microsoft made a large number of nice, polished changes to things like Notepad that haven’t seem to been updated in decades.

  4. Well at least Notepad is getting some minor tweaks…
    Sad to say that other than that, there is absolutely nothing compelling in the update.
    Truth be told though, I’m actually sick of Win10 now, and want a real OS again. This Windows as a Service lark has had its day, and it’s time they started to change their attitude towards the user.
    The OS should serve the user. The user shouldn’t have to jump through hoops, to entertain some moron at Microsith.
    Right now, I am thinking that 8.1 is a better option, and I didn’t really like that compared to 7, but 10 is just turning me off, more and more, as time goes on.

  5. Hello, Changing the Windows Start Sound does not work with update from May 1903. It looks like something has changed internally in the system, Please can check failure.

  6. Other Features:
    “Anti-cheat software that is not updated to handle the security and stability changes made to the Windows kernel, will now crash with a Blue Screen of Death (BSOD).”


  7. Ribbon Disabler seems to be broken for 1903. Produces “EndUpdateResourceFailed: 13.” error. I miss it so!

  8. Unfortunately your “Windows 7 games for Windows 10” download no longer works in Build 1903. When I install it and try to open a game, it says, “Failed to Create DirectX Device.”
    Could you please fix this? I miss my 3 favorite games!

    1. Follow-up to my earlier comment – something must have gotten updated or fixed because it works now. Yay!

  9. W10 1903 also disables home networks (not to be confused with a homegroup) from printing to a shared usb printer hosted on a W10 desktop. Took me several days to fix it from all my W10 devices, but still it’s refusing connection from both my Macbooks. Getting a “connection refused” error as guest, and hold for authentication error when trying to connect with the correct credentials for this desktop. Worked perfectly as guest prior to 1903. Another intentional bug in the MS vs Apple pissing match.

  10. My network ralink adapter was missing/lost. I cant fix it when I updated my hp laptop. It started when my adapter connected to the internet and suddenly it’s gone, on and off. I cannot longer use the wifi adapter. I tried fixing it by opening the device manager and deleted the ralink adapter and restarted the laptop, but it didn’t work. I tried to install another adapter from Microsoft windows website but unfortunately nothing works. So I’m connecting my laptop to a LAN. It’s so upsetting. Any suggestions that could help me? Thank you very much!
