It sounds like you're experiencing significant frustration with Windows 11 and the transition from Windows 10. Many users have expressed concerns about the changes and challenges associated with the new operating system, especially regarding compatibility and performance issues.
Microsoft has indicated that Windows 10 will continue to receive support with monthly security updates until October 14, 2025, which might have been a viable option for you had you known about it earlier. Additionally, the final version of Windows 10 is 22H2, and it will still be supported until the end of its lifecycle.
If you're considering alternatives, it's worth noting that some organizations and users are exploring options like Linux for their operating systems, especially if they find that Windows does not meet their needs or expectations. However, transitioning to a different operating system can also come with its own set of challenges and learning curves.
For specific issues with Windows 11, it may be beneficial to reach out to Microsoft support or check community forums for troubleshooting tips and potential solutions to improve your experience with the OS.
