Make sure you Update hardware drivers or you maye run into problems installing.
If you are updating from an older version of Windows 10 (version 1903 and 1909), the process of updating to the current version will be the same as it has been for previous Windows 10 feature updates.
In this release, Windows Defender System Guard enables an even higher level of System Management Mode (SMM) Firmware Protection that goes beyond checking the OS memory and secrets to additional resources like registers and IO.
With this improvement, the OS can detect a higher level of SMM compliance, enabling devices to be even more hardened against SMM exploits and vulnerabilities. This feature is forward-looking and currently requires new hardware available soon.
In Windows 10, version 2004, SetupDiag is now automatically installed.
SetupDiag is a command-line tool that can help diagnose why a Windows 10 update failed. SetupDiag works by searching Windows Setup log files. When searching log files, SetupDiag uses a set of rules to match known issues.
During the upgrade process, Windows Setup will extract all its sources files to the %SystemDrive%$Windows.~bt\Sources directory. With Windows 10, version 2004 and later, Windows Setup now also installs SetupDiag.exe to this directory. If there is an issue with the upgrade, SetupDiag is automatically run to determine the cause of the failure. If the upgrade process proceeds normally, this directory is moved under %SystemDrive%\Windows.Old for cleanup.
With this release, you can configure Windows Autopilot user-driven Hybrid Azure Active Directory join with VPN support. This support is also backported to Windows 10, version 1909 and 1903.
If you configure the language settings in the Autopilot profile and the device is connected to Ethernet, all scenarios will now skip the language, locale, and keyboard pages. In previous versions, this was only supported with self-deploying profiles.
An in-place upgrade wizard is available in Configuration Manager. For more information, see Simplifying Windows 10 deployment with Configuration Manager.
