Microsoft looks poised to release the following major update of Windows 10 after May. We don't know the exact date for when the Windows 10 May 2020 update will roll out, but the company have accidentally confirmed a three-day launch window.

Posted around the Microsoft Tech Discussion board (via Windows Latest), a "Driver Shiproom Schedule," reveals intends to begin rolling out the May 2020 Update between May 26 and May 28. The post shows a 2020 calendar color-coded by weekends, holidays and dates reserved for feature and minor updates.

In line with the calendar, the next feature update is going to be delivered , Wednesday, or Thursday from the a week ago in May. This aligns with what has been said in rumors: that the May 2020 update will arrive on May 28.

Of course, these dates are always subject to change as Microsoft irons out bugs or finds new problems, as it did with the Deployment Image Servicing and Management tool earlier this year.

Unfortunately, another months around the posted calendar weren't updated with expected feature update launch dates.

Windows 10 May 2020 update features

Once the May 2020 update arrives on Windows 10 laptops, it will bring several minor changes.

What Microsoft is calling the "new Cortana experience" is arguably the largest one. Cortana, the digital voice assistant currently embedded in the Search bar, will appear like a dedicated icon right of Search.

Microsoft will also add quick search buttons towards the bottom from the main Search bar, and some index tinkering could improve the speed of older laptops with hard disk drives (HDD).

We might also see updates to Windows 10 icons. Microsoft revealed new icons as part of its efforts to modernize the operating system. Countless icons, from the documents folder to the iconic mail envelope, will be refreshed. It isn't clear if the will happen within the May 2020 update or later this season.

Microsoft can't seem to to produce new version of Windows 10 without breaking things on the way. So, as a word of caution, you might like to wait a few days or weeks before downloading the update -- just to be safe and sound.
