If you install Windows 11 on an unsupported PC, you will not get updates

You can always install Ubuntu or Linux Mint Being a Linux evangelist it would be very remiss of me not to at least mention it is an option that you have. Linux Distros like Ubuntu and Linux Mint are quite user friendly and easy to set up. It’s a lot easier to install Ubuntu on your laptop or PC than it is to install Windows. You can even install Ubuntu or Linux Mint alongside Windows and choose which OS you want to boot into during startup. I am always telling people that these days it doesn’t really matter which OS you are using as long as you can install Google Chrome. Most of the stuff we do and need is in the cloud. If you are an accountant for example you can use Sage or QuickBooks in the cloud so there is no need for Windows support. You can use Office 365 or Google Workspace and so much more. Your OS just sits behind the scenes unobtrusively facilitating your desires. There was a time when desktop apps ruled the roost and this was a big reason for you not to install Linux but those days are long gone. Ubuntu 20.04 will be supported for the next 10 years so, 2030 inenge ichipo! Ubuntu will also run much faster than Windows 11 will ever will on your old Hardware. You can do that or just keep Windows 10 which Microsoft has said they will keep supporting and updating. Read more
