Of course, this naturally leads to the next question:should you install Windows 11 right now?We’d actually recommend holding off for a while. This is essentially day one of the new OS, and from past experience, things can be flaky to start with. Unless there’s some pressing reason to do so, sticking with Windows 10 in the short term is probably a wiser idea.

From here you have a couple of options. The first is that you can drop the ISO file onto any existing Windows machine and perform either an in-place update or a clean install over the top of the current installation.

You can also create a bootable USB stick to install the Windows 11 Insider Preview on different devices. Microsoft recommends a third-party app, calledRufus, because it is relatively easy to use and lightweight in terms of system resources.

Alan has been writing about PC tech since before 3D graphics cards existed, and still vividly recalls having to fight with MS-DOS just to get games to load.
