Defer preview builds to (drastically) minimize incompatibility support requests

As support technicians specialized in Remote Access for many years, we recommend to our customers to defer 10 days preview builds and feature updates, in order to avoid incompatibility cases between termsrv.dll and Remote Access kernel.

As an example, on Server 2025 the local policy that controls this is:

Computer Configuration > Administrative Templates > Windows Components > Windows Updates > Manage updates offered from Windows Update > Select when Preview Builds and Feature Updates are received

To illustrate the impact of this setting, here is a video in the current context of KB5058499 released two days ago:

Finally, we leave you the command lines we used to enable/disable this behavior:

reg add "hklm\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v DeferFeatureUpdates /t REG_DWORD /d 1 /f reg add "hklm\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v DeferFeatureUpdatesPeriodInDays /t REG_DWORD /d 10 /f

reg delete "hklm\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v DeferFeatureUpdates /f reg delete "hklm\SOFTWARE\Policies\Microsoft\Windows\WindowsUpdate" /v DeferFeatureUpdatesPeriodInDays /f

Thank you for your attention and best regards!
