> A system snapshot for a personal computer is potentially a really difficult thing to restore (ex. you break the device and need a new one, unless it matches exactly restoring snapshot likely puts you in OS recovery mode).

While I am sure the process has limitations, I think that modern Windows has some amount of flexibility there, because due to a defect I've recently had to swap out my mainboard + CPU, and the system booted up just fine. The most major issue was that with the default drivers Windows had reverted to, the Ethernet controller didn't work, which could have been a little bit of a Catch-22 (no internet without the correct drivers, and no correct drivers without internet), but in practice I just downloaded the drivers on a different device and transferred them over via USB.
