May is finally here and many users are excited to see what the next big feature update is all about, especially since Windows 10 v21H1 has been announced and teased so much over the past months.
Of course, today is also the day the monthly Patch Tuesday updates hit live, and as always, they bring a host of new features, improvements, and fixes for the most common Microsoft bugs found over the last month.

Changes included in the May Patch Tuesday Updates
Table of content
Windows 10, version 20H2
As of the writing of this article, Windows 10 v20H2 is the latest major version of Windows 10, and as such has the most experimental features on it.
Fortunately, most bugs that were first present when it was first made available have been weeded out, and this version of Windows 10 is far more stable.
That being said, you should upgrade to this version as soon as possible if your hardware allows it (the system requirements are the same as with Windows 10 v2004).
If you haven’t updated to Windows 10 v20H2, know that it is easiest to update if you already have Windows 10 v2004. Check out this in-depth guide on how to get Windows 10 v20H2 as fast as possible.
Cumulative update name:
Improvements and fixes:
- Security updates to Windows App Platform and Frameworks, the Windows Kernel, Windows Media, the Microsoft Scripting Engine, and the Windows Silicon Platform.
Known Issues:
- System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be impacted if they have already installed any Latest cumulative update (LCU) released September 16, 2020 or later and then proceed to update to a later version of Windows 10 from media or an installation source that does not have an LCU released October 13, 2020 or later integrated.
- This primarily happens when managed devices are updated using outdated bundles or media through an update management tool such as Windows Server Update Services (WSUS) or Microsoft Endpoint Configuration Manager. This might also happen when using outdated physical media or ISO images that do not have the latest updates integrated.
Tip
- Devices with Windows installations created from custom offline media or custom ISO image might have Microsoft Edge Legacy removed by this update, but not automatically replaced by the new Microsoft Edge. This issue is only encountered when custom offline media or ISO images are created by slipstreaming this update into the image without having first installed the standalone servicing stack update (SSU) released March 29, 2021 or later.

This concludes our list of changes that have come with the arrival of the May Patch Tuesday updates.
keep note that some of you may even get the option to uptae their PC entirely to the new Windows 10 21H1, although we recommend that you postpone that particular update for at least a couple of days to avoid day-1 bugs and errors.
You can do this for even longer periods of time (up to 35 days), although unless you have very serious reasons for doing so, we don’t recommend postponing for such a long time at all.
As for the generic cumulative updates, we recommend that you update your PC as soon as possible if you want to if you value your PC’s security and don’t want to fall victim to things like Exploit Wednesday or Uninstall Thursday.
If you’re not sure how you can get the latest updates installed on your PC, you should know that there are several methods that you can use:
- The Windows Update menu on your OS
- The WSUS (Windows Server Update Service)
- Group Policies set up by your admins if you’re part of a larger network.
