As usual, the updates come with bug fixes, tweaks, optimizations, and improvements for Windows 10, as well as the occasional new feature. Additionally, and most likely the most important part of all, the Patch Tuesday updates bring much-needed security updates, as well as a new list of CVEs that needed fixing. Speaking of which, this month’s Patch Tuesday updates come with fixes for 146 CVEs, and you can read more about them in this article. Additionally, as you may remember, the last round of Patch Tuesday updates were the first to bring anything of great significance to the new Windows 10 V2004, so many of you are probably wondering what else did this month brings. Without further ado, here is what this month brought for each major version of Windows 10. Note: We’ve also included direct download links for each cumulative update, so don’t hesitate to use them.
