When a new feature update becomes available, it often gives issues due to unknown bugs, driver issues, or internal updates in the OS. It is not possible to test all existing device configurations, so these are reasons for plenty of users to delay the update.


Windows 10 version 2004, known as '20H1', is the next feature update to Windows 10, which supersedes version 1909, '19H2'. It includes the following changes:

At the time of this writing, Microsoft only offers May 2020 update to users who have Windows 10 version 1903, and version 1909. It is available to 'seekers', e.g. you have to manually check for updates to get the upgrade offer in Windows 10 Settings. However, it is already possible to download the OS with Media Creation Tool, or get ISO images directly.

Windows 10 allows the user to delay updates available for the operating system. This option can be used to postpone the next feature update. Here is how it's done.

  4. Now, select for how long to defer feature updates. This option can be set to 0 - 365 days. Feature updates will install you a new build of Windows 10.Wufb Branch Readiness 1903 Original

So, to delay Windows 10 version 2004 as long as possible, you should set 365 days. Using these options, you will block the new feature update for the operating system.

Also, you can defer quality updates if required. They also can be deferred for many days: 0 - 365 days. These updates are monthly cumulative updates for the currently installed build of Windows 10.

  1. This ‘feature’ update was pushed to my pc automatically in the background. I never even opened settings.

    I didn’t know anything was happening until I got the “your pc needs to restart” notification.

    Luckily the “Go back to a previous version” in the recovery section worked fine.

    Windows 10 Pro
    Version 1909
    Build 18363.836

  2. My screen for item 4 “Now, select for how long to defer feature updates. This option can be set to 0 – 365 days. Feature updates will install you a new build of Windows 10.”
    does not have
    “Choose when updates will be installed”
    It has only
    Update options
    Update notifications
    Pause updates

  3. )in Windows 10 Pro……..Quality Update range is NOT 365 days (as stated)……

    Quality Update Range is 0 – 30 days.

  4. Damn. With version 2004 you can’t defer updates to a fixed amount of days anymore This was the only reason I cared for the Pro version of Windows. Damn MS! Now it’s like the home version, where you can delay just the next incoming update, for one month. Like how dumb is that move. I can already see my workstation bricked again.

  5. 2004 caused issues uploading images to blogger, they would just hang there. Tried to upload on a Post then a Page, a different website and a different browser. All had exactly the same issue. Went back to the earlier build and had no problem uploading images. Do not know of any other issues because I hadn’t used the PC since the update and then I reverted soon after.

  6. This did not work for me. I made the Registry changes exactly as you specified.

    But it is still forcing the horrific switch to Windows 10 version 2004

    That version kills the sound on my new Dell desktop computer
