There are several reasons why the installation or finalization of one or more Windows updates can hang.

I was looking at Windows Update under my settings, to make sure I was up to date, but it seems Windows Update has been stuck checking for updates. Or Windows 10 feature update version 21H1 stuck downloading at 48 % or any other figure, fails to install. But some of the users report Windows 10 update stuck checking for updates forever. Or sometimes we need to manually check for updates from windows settings, update & security check for updates.

That means whenever a new update is available, that download and install automatically via windows update. And with Windows 10 updates set to install automatically. Microsoft regularly releases Windows updates to fix the security hole created by third-party applications, with security improvements and bug fixes.
