Technically until the first security update is released after Oct 2025. However as long as a user isn’t downloading dodgy programs or visiting strange websites then there should be no problem for a while. There’s always the option to force upgrade to Windows 11 on non compliant devices which, as long as upgrade can be installed, will extend security.
My laptop is fine apart from the cpu isn’t supported but I have installed Win 11 & the 23H2 update installed via an update.
