Microsoft says that customers who install the optional KB4577062 update for Windows 10 versions 1903 and 1909 will encounter issues upgrading to newer Windows 10 versions on some devices.

"When updating to Windows 10, version 1903 or Windows 10, version 1909 from any previous version of Windows 10, you might receive a compatibility report dialog with 'What needs your attention' at the top and the error, 'Continuing with the installation of Windows will remove some optional features. You may need to add them back in Settings after the installation completes'," Microsoft explains.

While Microsoft doesn't mention that the compatibility issues caused by KB4577062 also affect newer Windows 10 releases, Günter Born reports that users have also seen this warning when trying to upgrade to Windows 10, version 2004.

The company advises customers to work around this known issue by re-enabling HTTP access to the Internet to the Windows 10 Setup Dynamic Update.

"If your device has access to HTTP blocked for LOCAL SYSTEM accounts, to mitigate this issue you can enable HTTP access for the Windows 10 Setup Dynamic Update using the LOCAL SYSTEM account," Microsoft says on the KB4577062 support page.
