Windows 10 is fully supported (Windows and Microsoft Defender updates, etc.) through October 14, 2025 (approximately 4 more years).
Windows 11 can be clean installed in most computers including desktops, laptops, and tablets.
To test drive Windows 11 you can use third party software to make free backup images.
Then you can clean install Windows 11 > test drive > restore an image when you've completed the test drive.
Windows 10 can be upgraded to Windows 11 if the end user modifies the registry and files so that the upgrade assistant no longer recognizes the checked parameters.
These methods are available on multiple websites.
