by ·

KB4556803 is the cumulative update that Microsoft just released to Windows 10 version 2004, and the corresponding version is Windows 10 Build 19041.264. Users need to check the update after installing the update to install this cumulative update.

The content of the update is mainly to fix multiple security issues, and it is precisely because of a serious security problem that Microsoft has been delayed to release the Windows 10 version 2004 iso image file until now.

Windows Server Insider Preview Build 18945

In addition, this update will also fix the problems encountered by the Disk Cleanup tool in the latest version. After installing the update, users can normally clean up the disk redundant files.
