How can I prevent 20H2 from installing

This has been a problem for me. I had to revert back to the previous build twice now. This is my main production machine and cannot afford to waste time on this. Each time a revert back it continue to want to install build 20H2. Is there a way to prevent this from installing?
The first time I ran the build I had all components stop working. I truly only had the keyboard and touch pad on my laptop working. Reverted back to previous build. Decided to run it again and all appears fine except that I could not connect to my domain controller. I could ping it. I could connect to a Windows 10 computer on the network as well. Disable VS and firewall on laptop and DC. I could connect with other PC to DC.
Any help appreciated.

    @Computer Gladiator There is a wealth of information about managing Windows 10 Updates at 2000016-guide-for-windows-update-settings-for-windows-10

    As others have commented, you can use group policy or registry settings to control the way that Windows 10 updates itself. The above reference mentions two registry values - TargetReleaseVersion (REG_DWORD) and TargetReleaseVersionInfo (REG_SZ).

    @Computer Gladiator
    Hi,
    You can use the “Select the target Feature Update version” policy to block the feature update.
    If the device is running Windows 10 Pro or Enterprise, you can use the Group Policy Editor to set target feature update version.
    To configure a target feature update version with Group Policy, use these steps:
    Search for gpedit and click the top result to open the Group Policy Editor.

    Browse the following path:
    Computer Configuration > Administrative Templates > Windows Components > Windows Update > Windows Update for Business
    Double-click the Select target Feature Update version policy.
    Check the Enabled option.
    Under the “Options” section, confirm the target version of the feature update you want to set the device. For example, 2004 for the May 2020 Update or 20H2 for next feature update coming in 2020.
    Click the Apply button.

    Hope above information can help you.

    Hello,

    Can you share us what is your current version?

    In the meantime, you can try this:

    1. Open Registry Editor.
    2. Go to HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate.
    3. Create TargetReleaseVersion registry DWORD.
    4. Set its Value data to the Windows 10 version you want. For example, if you want to stay on Version 2004, use 2004 as Value data.
    5. Close Registry Editor and reboot to make changes effective.

    Hope this helps!
