Microsoft has not officially announced or released Windows 12 as of April 2023. Therefore

As of April 2023, Microsoft has not officially announced Windows 12. After Windows 10, Microsoft has been releasing updates and feature upgrades for Windows 10 on a regular basis, rather than releasing a completely new version of Windows. These updates have included significant changes and improvements to the operating system, and it's likely that Microsoft will continue to focus on updating and improving Windows 10 rather than releasing a new version.

It's important to note that there are some fake websites and scams claiming to offer Windows 12 downloads or upgrades, but these are not legitimate and could potentially harm your computer. It's always best to only download and install software from trusted sources.
