I would counsel extreme caution, certainly in the short term. I've seen reports, mainly on Youtube from reasonably reputable bloggers and tech experts, that Win 11 is doing some very strange things (inter alia generating vast quantities of random empty folders, folders not showing in the file explorer when they patently do exist, considerable (up to 30%) performance/speed downgrades especially with AMD processors, etc). I am not aware of anything overtly dangerous, but, it would appear that, they really haven't a very good QA job on this product.
The option to revert to Win 10 period has been reduced to 10 days, rather than 30 days, as was the case when upgrading to Win 10 from 7/8/8.1.
Lastly MS are in a major push to collect user information to 'on-sell', (which is how they make their money!!). They do this by setting up the OS to assume approval to harvest info from users if that approval is not specifically denied. Considerable set up operations are required to ensure that MS cannot get at your info. Beware!! Google employ the same strategy.
Have you run the 'Can I run Windows 11 App'? (free download from MS) Google it. Your Laptop may well be too old. On the upside W10 updates will be available till 14 Oct 2025. They should have Win10 sorted out by then, it will have only taken a decade to get it right - so your laptop should be good for another 4-5 years after that
