Security updates for Windows 10 are released twice every month, with the biggest and most important of them being released during Patch Tuesday, while the second ones come 2 weeks later in the form of smaller patch fixes.
Well, Microsoft just released the April Patch Tuesday updates, and it includes security update KB5001330 which applies to Windows 10 v20H2 and v2004.
This update stands out compared to the other ones released today because it affects the way Microsoft Edge (Legacy) is being handled from certain Windows installations.
Microsoft Edge Legacy may not be properly replaced
According to Microsoft’s official changelog covering KB5001330, it seems that the process of replacing Microsoft Edge Legacy with the new version is being hindered when applying this security update:
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.
However, they did note that devices that connect directly to Windows Update to receive updates are not affected, including those using Windows Update for Business, and that devices connecting to Windows Update should always receive the latest versions of the SSU and the latest cumulative update without issues.
As such, if you plan to install a fresh new copy of Windows 10 v20H2 or v2004 from an offline source, such as an ISO created with the Media Creation Tool, it is better that you wait until this issue is fixed.
We hope that this brief intro into what security update KB5001330 brings will make it clearer for you whether you should update now, or wait for the patch fixes that are to come in 2 weeks.
Keep in mind that the option of postponing Windows 10 updates is also available, as you can do it for up to 35 days.
However, keep in mind that not updating your PC comes with its own downsides, especially given the overall purpose of Patch Tuesday.
To ensure that the update process goes smoothly, we recommend that you follow certain steps to ensure an error-free system upgrade.
