Nearly any PC that has the capability to run Windows 10 will be able to have Windows 11 installed. The catch is that it will be a little tricky to do for anybody whose PC has unsupported hardware. Those users will have to make the update with a Windows 11 ISO file. Those with a PC that is compatible will be able to easily run an update to install Windows 11. Microsoft says Windows 11 can run on older devices. But the reality is you’re going to spend more time supporting them and dealing with their anomalies. Does a 5 years pc need a replacement for Windows 11 ?
