Last night, Microsoft released a new Windows 10 Insider Preview Build for those in the Dev Channel along with a fixes-full update for Insiders in the Beta and Release Preview Channels. The Windows maker has followed these two updates with a new release for the public. Windows 10 version 1909 and version 1809 users have received January 2021 monthly "C" release preview updates.

Tagged as "preview," you can choose to install these optional, non-security updates, but are advised to wait until the next Patch Tuesday to get these fixes. Microsoft said that the preview updates for 2020's Windows 10 versions 20H2 and 2004 will be made available later.
