Maybe, but Microsoft forces any consumer who buys a pre-built PC to buy Microsoft Windows and counts them as a user. Even many computers with Linux pre-installed are merely PCs that originally had Windows with their drives reformatted. Unless you build a PC from scratch, it probably is counted as a "Windows" PC.
I know that I have bought at least SIX laptops that are counted as running Windows, two even came with Linux "pre-installed" but I know they were originally shipped with Windows.
None of them run Windows. They just count as if they do.
