The Windows 10 May 2021 Update, also known by the 21H1 index, has been around for two months – Microsoft called it stable (safe) and, starting in late June, is moving to force users to update the outdated version of Windows 10 to version 21H1. The Windows Latest edition reported this.
A forced upgrade to Windows 10 version 21H1 will affect people who are still using build 2004, introduced in May 2020. Shortly, the reason is that support for this version of the system will end (in December 2021) – this is standard practice for Microsoft. The company begins to send forced updates to users of outdated versions of Windows 10 six months before the end of support.
Windows 10 version 21H1 is based on the 20H2 update, so that the update will be quick and easy – many users will probably not even notice it. Also earlier, Microsoft made the 21H1 update fully available to all users – you can also install it manually by checking for availability in the Windows settings.
