Yesterday Microsoft finally rolled out Windows 10 May 2020 Update for everyone. The latest update comes with new features and improvements. However, like all Windows 10 updates, the May 2020 Update will not be available for everyone as OEMs need to roll out drivers to ensure the hardware is compatible with the update.
To protect users from running into issues, Microsoft puts out a list of known issues and blocks the update on specific devices until the issues are resolved. Microsoft did the same for Windows 10 May 2020 Update but the company has now published a separate document (via Techdows) confirming that it has blocked the update on PCs that have Hypervisor-protected code integrity (HVCI) or Memory Integrity enabled. If you try updating your PC with Memory Integrity enabled, you will receive the message, "Your PC settings need to be adjusted before upgrading to the latest version of Windows 10. Turn off memory integrity protection to continue." Microsoft has listed the following as the cause:
An incompatibility has been found with certain display drivers and Windows 10, version 2004 when memory integrity protection is enabled.
To safeguard your update experience, we have applied a compatibility hold on these devices from installing or being offered Windows 10, version 2004.
Fortunately, there is an easy workaround for the issue. Microsoft has identified an incompatibility with certain display drivers so you just need to download and install the new drivers from your manufacturer's website and you should be good to go. If your manufacturer has not released the new drivers then you can follow the steps below to disable Memory Integrity and safely update your PC:
- Open Start Menu and search for Windows Security.
- Navigate to Device Security > Core Isolation.
- Now click on the toggle to turn off Memory Integrity.
- Restart your computer.
Microsoft has noted that it is "working on a resolution and will provide an update in an upcoming release." While Microsoft has released the Media Creation Tool for the Windows 10 May 2020 Update, it is not advised to manually install the update using Media Creation Tool or ISO as hardware incompatibility may make your system unstable.
