In earlier versions of Windows operating system, end users had more control over Windows Updates. Unfortunately, Windows 10 offers us very little control over Windows Updates. While this move ensures that all PCs automatically receive Windows Updates and are up-to-date, many users are not happy with this behavior of Windows Update in Windows 10. As you likely know, when you check for updates via the Windows Update section in Windows 10 Settings, it doesn’t display the download size of available updates. While those who are on unlimited internet connection plans might not to know the size of updates, users who are on metered connection might want to know the size of updates before downloading and installing them.
