Microsoft Windows had gone through a number of updates and we all might have seen the different versions of the windows with latest being 10 S. However one department where Microsoft was not as successful as it could have been releasing a lightweight OS version of Windows.
A tweet which claims to show a leaked internal memo sent to PC dealers in China has now suggested that Microsoft will begin rolling out next Windows 10 version on May 9 in China (via Neowin), which would be May 8 afternoon in the United States.
According to Twitter used Lucan (who first noticed the edition, H/T MSPowerUser), the build is 2GB lighter than the standard Windows 10 Pro installer, and cuts out superfluous options such as desktop wallpapers.
While ZDNet's Mary Jo Foley speculated in a chat with Lucan that Windows 10 Lean could simply be S mode for Enterprise or Home editions, now there is no clarity as to what Microsoft plans to do with the release of Windows 10 Lean.
Regedit appears to be missing, but CMD and reg.exe are present and accounted for.
We don't know yet what Microsoft intends to do with this new version of Windows 10.
There are a couple of new features in this build. So it could be a possibility that Windows 10 lean is the redesigned Windows 10 S. However, Windows 10 Lean does include placeholder buttons that allows you to download and install an app or feature as necessary.
Microsoft will also be busy with BUILD 2018 starting from May 7 and might use that opportunity to finally officially announce Windows 10 1803, or 1804 (it's now getting beyond the point of confusion). Or is Lean set to replace 10 S entirely now that the former version has been turned into a mode for Windows 10 rather than a distinct operating system.
