Microsoft has confirmed that there was a bug in the Windows Security security application that caused the PC to fail to complete the installation of the Windows 10 2020 May update (Version 2004). According to Microsoft, this compatibility issue cannot be eliminated by not modifying Windows Security’s memory integrity settings in the software. If you don’t want to discard memory integrity, you can also try getting a new display driver from the manufacturer to unblock the upgrade from Windows 10 2004.
To temporarily turn off Windows Security’s memory integrity checking feature, refer to the following:
Go to Windows 10 settings;
Move to update and security;
Move to Windows Security;
Click on device security;
Select Core Isolation Details;
Switch memory integrity settings;
Restart the computer.
You can then manually check for Windows 10 2004 updates in Windows Update, or get them with the Update Assistant.
If you still don’t see the update, make sure your device has updated the Intel/NV GPU display driver, or the vendor’s Bluetooth device driver. Microsoft has previously warned that choosing to ignore security issues and manually force update Windows 10 2004 using media creation assistants (or other programs) could have a series of unknowable consequences.
