Microsoft was planning on releasing Windows 10X soon, which would rewrite the operating system from the ground up. Now reports indicate that the project may be dead in favor of the current incarnation of Windows X. Leo says the problem is that Microsoft is obsessed with keeping the OS compatible with every computer out there, making it practically impossible to modernize it.
Neil has a Sony Vaio laptop running Windows XP and knows he should upgrade to Windows 10. Can he and still run 32 bit? Leo says that 32 bit won't be a problem with Windows 10, but the machine may be too old and not have enough RAM to run it. It's worth a try though, and you can roll it back if it doesn't work well. What you could try is to download the Windows 10 Media Creation Tool, burn it to a DVD and then boot to that DVD to see if it'll run. If it does, however, it'll likely be really slow. Leo advises using Linux on it.
