If you’re a normal geek, you likely play around with various operating systems and releases. Often, I find that trying out various betas can not only leave you confused about what’s been officially released, it can also confuse your computer.
I typically use a mixture of virtual and actual machines for my beta testing, and I often use the laptop I have at home for betas. (At work it’s too important to have a machine run possibly non-stable code.)
This leads to interesting situations at home, where I have an older laptop that works great for typing up Computerworld post and remote accessing various servers, workstations, and cloud services, but is not good enough for Windows 11.
