Support for Windows 10 ended in October 2025. Staying on it means no longer receiving security fixes - whatever antivirus you have.
It is not an overnight emergency : your machine keeps working. But the flaws found after the end of support will never be fixed, and they accumulate. So the question deserves dealing with rather than waiting for an incident.
The simplest way : Settings > Windows Update. If the machine is eligible, the upgrade is offered there directly. If not, Windows generally explains why it is refused.
Microsoft also offers a PC Health Check tool that sets out point by point what is blocking it.
In other words, a machine declared incompatible often is not really : two settings to change are enough in a good number of cases.
Three options, in order of cost :
Procedures circulate for installing Windows 11 on unsupported hardware. They work technically, but Microsoft warns that such machines may stop receiving updates - which cancels the whole point of the exercise. Keep it for secondary machines, with your eyes open.
The upgrade keeps documents, programs and settings. That said, the rule is the same as for any major operation : back your documents up to an external medium before starting anything. Allow one to two hours, with the machine on mains power, and do not interrupt it.
One practical tip : moving to Windows 11 is also a good moment to fit an SSD if the machine still runs on a mechanical drive. It is done in one go, with a clean system. See SSD or hard drive.

No, it keeps working normally. It is the security fixes that stop, which leaves the machine progressively more exposed to known flaws.
No, it is free for eligible machines with a valid Windows 10 licence.
Yes, for a limited period after the migration - ten days as a rule. After that, going back requires a full reinstall.
