A question that will truly haunt philosophers for centuries to come

If one replaces a few EXEs and DLLs at a time, at what point does it become Windows 11 ?

When it starts spamming you ads from the taskbar...

If that's the stop point, they'll only end up with Windows 8 and miss out on Recall.

When you need to buy new hardware to boot it.

Without new hardware, old hardware would eventually die.

When that old hardware dies, it would likely be replaced with a similar design rather than more evolved hardware. This would mean we’d have to develop for longevity. Developing for longevity, could mean that software would flourish. Software flourishing could include malware and inefficient software sold to fight malware. Therefore, it is more secure and efficient to continually evolve operating systems to require new hardware, to reduce longevity and the flourishing of software.

It becomes The Windows of Theseus.

Is the a 32 bit version of windows 11?

When it asks for a Microsoft account.

Which it did first time I think vista?

To Linux or not to Linux?
