Windows 10 as a service is updated frequently with
improvements, fixes, and security patches. On every second
Tuesday of the month, a compulsory Windows 10 update is
released and optional updates are also shipped every month.
Windows Updates are normally installed automatically in the
background. If the system finds any updates, it usually
downloads and installs them automatically, but sometimes
updates may not appear on your computer.
Fortunately, Microsoft allows users to manually download
Windows 10 cumulative updates and security-only updates. You
can use Microsoft’s Update Catalog to quickly install a
cumulative update on your PC if it’s not showing through the
preferred Windows Update method.
In this article, we’ll walk you through the steps to download
