What is your service tag for the Dell, just out of curiosity?
While Windows 10 will be end of life in 2025, there will be an extended service update (ESU) available to purchase for max 3 years, extended the life of Windows 10. You will continue to get security updates, but no new features.
Also to add to JohnB's post, I have seen in other technical forums that some posts into another's thread with a similar problem, it gets confusing on who we are helping.

A new thread is always the best solution, and you and link the URL to the other thread if needed.
