Windows 10 will reach end of support on October 14, 2025. The current version, 22H2, will be the final version of Windows 10, and all editions will remain in support with monthly security update releases through that date. Existing LTSC releases will continue to receive updates beyond that date based on their specific lifecycles.
I'd recommend doing a dual boot sooner and slowly shifting your files & apps. It took me about 3 months to find a distro and desktop environment i like, get my apps or alternatives installed, and get used to it.
If you wait until EOL, you may be overwhelmed and frustrated, increasing the likelihood of calling quits and accepting Windows 11.
